Principles and techniques of forming a sparse-tiered crown. Formation of the crown of fruit trees Small-sized sparse-tiered crown

There are many types of crowns. However, in collective and home gardens for strong and medium-sized trees on seed rootstocks, the most common is sparsely layered. The sparsely tiered crown ensures the strength of its skeleton, good lighting, which means high photosynthesis efficiency, tree productivity, and ease of care.

The standard for apple and pear trees on seed rootstocks is 70-80 cm. The crown skeleton consists of 5-7 branches. Of these, two or three are formed in the first (lower) tier. Two are selected from shoots located through one bud, or better yet through two, the lower ones at a distance of about 10 cm from each other, and the third, upper one, -20 cm from them (so that the crowding of skeletal branches in the tier does not weaken the central conductor). The angles of departure of the skeletal branches are 45-50° to the vertical, and the angles of divergence between them (horizontally) are 120° and 180°.

The remaining skeletal branches are laid higher, evenly along the length of the trunk: the first of them - 50-60 cm from the upper branch of the first tier, on the opposite side from it (for varieties with a pyramidal and dense crown - after 80 cm).

The branches of the upper sparse tier are placed evenly around the trunk at a distance of 30-40 cm from each other. Moreover, their projections should be between the skeletal branches of the lower tier. For a sparsely layered crown, it is important that the upper tier contains no fewer skeletal branches than the lower one. In varieties with a naturally pyramidal crown, the number of skeletal branches in the upper sparse tier should be even greater than in the lower one (for example, if there are three in the lower one, then there are four in the upper one; if there are two in the lower one, then there are three in the upper one). In addition, it is necessary to correct the sharp angles of branches in different ways: using spacers, cutting to transfer, overlapping and braiding branches behind adjacent branches; also use hanging weights, ropes for pulling branches to lower branches, a standard (a clove hammered into it), neighboring trees, and pegs driven into the ground.

The skeletal branches of the lower tier are directed mainly towards the sides of the row spacing, but not more than 45° to the row line (so as not to interfere with the processing of the row spacing). And the branches of the upper tier are placed in all directions.

Skeletal branches of the second order (lateral, grown on skeletal branches of the first order, which extend from the trunk) form only in the lower tier - two or three on each skeletal branch and alternately on different sides, at a distance of 45-60 cm from the trunk and among themselves . Their opposite pair arrangement is unacceptable - this depresses the carrier branch, it becomes weaker than them and may wither.

In the upper tier, on the skeletal branches of the first order, one or two semi-skeletal branches are formed, since the skeletal branches of the second order in the upper tier exaggerate the crown. Some even recommend planting only overgrown branches on the skeletal branches of the upper tier.

Semi-skeletal branches (third order) about 1.5 m long are formed from lateral branches with angles of departure in the lower tier of 50-60 °, and in the upper tier - 70-80 °. They are given this angle by deviation. Branches of the third order are placed on the skeletal branches of the first and second orders and the trunk at intervals of 20-40 cm from the bases of the skeletal branches and among themselves. For densely crowned varieties - at a distance of 60-70 cm.

Overgrowing (fourth order) fruit branches 50-90 cm long should cover all skeletal, semi-skeletal branches and the trunk every 10-20 cm.

All pome and many stone fruits are formed according to a sparse-tiered system - with modifications.

When forming and pruning the crowns of all species, you must remember and follow the following rules:

When pruning, close attention should be paid to the angles of branches. Their growth and fruiting, as well as the strength of fusion with the carriers, depend on this. Branches growing vertically and at sharp angles to the vertical grow intensively, but bear fruit poorly and do not grow firmly with their carriers. And branches growing close to the horizontal bear fruit abundantly, but grow poorly. This is also not always good, since a balance must be maintained between growth and fruiting. The optimal angle of departure is 50-60 °. True, there are nuances: for example, it is better to form the skeletal branches of the lower tier at an angle of 45-50 ° (this makes processing easier tree trunk circles), and semi-skeletal branches of the upper tier - 70-80 ° (so that the crown does not become too high and apical growth is inhibited, which is very intense in the branches of the upper tier).

When forming the crown, it is necessary to observe the law of subordination of branches of different orders and tiers between each other and the trunk: the thickness of the skeletal branches of the first order should be 0.6-0.8 of the thickness of the trunk at the point of fusion; the thickness of the skeletal branches of the upper tier should be approximately the same as the thickness of the first-order skeletal branches of the lower tier; skeletal branches of the second order - 0.6-0.7 times the thickness of their skeletal branches of the first order (they should be shorter by another 1-1.5 m); semi-skeletal branches - 0.5 thickness of their skeletal carrier branches. The tops of branches of higher orders should be lower than the tops of their carrier branches: in varieties with spreading and spherical crowns by 15-20 cm, in varieties with pyramidal crowns - by 25-30 cm.

A sparsely tiered crown is formed from 5-6 branches instead of the previous 5-8. The branches are placed in tiers and sparsely, and the tier is limited to two or three adjacent or close branches.

With the previous eight branches, in most varieties it was allowed to leave three adjacent branches in the lower tier. The presence of 4-5 branches above this tier ensures that sufficient conductor power is maintained and inhibits excessive reinforcement of the lower branches. Only in varieties with weak mechanical connections and eight branches was the tier limited to two branches. When forming a crown of 5-6 branches, the tier should be limited to two branches and in all varieties with a pyramidal crown. The small deviation of the branches characteristic of these varieties enhances their growth and under these conditions three branches above the three-legged tier will not provide the necessary predominance of the conductor.

In a crown of eight branches in the lower tier, four branches were also allowed through the bud. With 5-6 branches, such a layer is completely excluded: laying 1-2 branches above a four-branch group is not sufficient for the development of a strong leader.

In varieties with a wide crown, when planting six branches, up to three adjacent branches can be left in the lower tier. If the crown is formed of only five branches, then in these varieties the lower tier should be limited to two branches.

For trees with two branches in the lower tier, another pair of adjacent branches can be placed in the middle part of the crown. But in an open crown above the middle tier, at least two single branches must be laid in two adjacent branches: after cutting out the continuation of the conductor, one final branch above the two-branch tier does not provide sufficient dominance of the conductor in the upper part of the crown. In cases where the continuation of the conductor is preserved, one final branch is sufficient above the two-knot tier. This provision defines the following possible options branch placement:
a) in an open crown of six branches, the lower tier is of three branches, and the next three are sparse; the lower and second tiers of two branches; the top two are single;
b) in a crown of five branches - the lower tier consists of two branches, and the rest are sparse.

When laying two branches in the lower tier, the third on the opposite side of the trunk can be selected at a short distance - within 15-30 cm. In the middle zone and in the south, the following branches are laid at intervals of 60-100 cm, and in varieties with a wide crown they can be left intervals of 60-80 cm, while others require an interval of 80-100 cm. In more severe areas, the interval can be reduced to 50-60 cm.

The interval between single branches in the middle and upper parts crown depends on the position of the upper branch in relation to the underlying ones. If it is directed in the opposite direction from the angle of divergence of the two lower branches, the interval can be small, within 20-40 cm. Otherwise, the interval is increased to 60-80 cm.

The general rule for placing branches is as follows. Each branch located above the angle of divergence of the underlying two must be separated from them by a large distance (the distance is calculated from the base of the upper one). No more time is spent on laying five to six branches with increased intervals between groups and individual branches than on laying eight branches.

In gardens with sparse trees (more than 4 m in a row), the crown can be formed from skeletal branches of the first and second orders, although it is better to limit it to one branching order. Branches of the second order are formed only on the three lower branches, no more than two on each. The third one can be selected as a backup.

The study showed that in a low canopy, growing second-order branches on the upper branches leads to thickening of the top. On the skeletal branches of the first and second orders, semi-skeletal branches of limited length are formed: within 1-1.5 m on the lower part of the branches and shorter at the top. Skeletal branches of the second order are placed sparsely on both sides of the main one, and semi-skeletal ones can be selected in groups of two or three on the lateral and outside skeletal branch.

Only the formation of semi-skeletal branches on the inside of the branch is not allowed. Between groups of semi-skeletal branches, an interval of 40-60 cm is maintained. In the south, in highly branched varieties, it can be increased to 80 cm. After the main branches are laid, the continuation of the conductor is removed, opening the crown.

With such formation sparsely tiered crown must have no more than 12 skeletal branches of both orders. The height of the crown is limited to 3.5-4 m. In gardens with a dense stand of trees (4 m in a row), the skeleton of the crown is built from branches of the same order. Semi-skeletal branches are formed on these branches.

In gardens with a higher planting density (less than 4 m in a row), the number of branches is reduced to 4-5 and 3-4, depending on the accepted density. When laying four branches, their approach is allowed only for the two lower ones, or all branches are placed sparsely. Forming a crown of three branches, they are placed only sparsely. In the latter case, the sparse-tier arrangement is replaced by a tiered one.

The basics for the formation of a sparsely-tiered crown are: inadmissibility of more than three branches in a tier and removal of the conductor above a close group of branches;
determining the required spacing and order of placement of branches depending on the divergence angles, the total number of branches and varietal characteristics;
limitation of skeletal orders.

​Next, individual branches within each tier are shortened and thinned out. Preference is given to branches extending from the skeletal ones at an angle of at least 45°. In the first tier they choose 4-5, in the second 3-4, in the third 2-3 branches. The rest are removed “on the ring.” If you need to remove a strong branch that has grown on a conductor or skeletal branch, it is removed not “on the ring,” but above the horizontal growth closest to the base of the branch being removed. If there are no lateral growths on it, it is cut off at a distance of 25 - 30 cm from the base. After pruning, several shoots appear on the branch. One of them, directed towards the outer part of the crown, is moved to a horizontal position, and the rest above it are removed in the spring of next year.

Every gardener knows how important it is to shape the crown of a growing apple tree. This procedure ensures that each leaf will be exposed to the sun for at least three hours every day. Sufficient exposure of the apple tree to sunlight allows each leaf to receive energy (nutrition). Otherwise, the energy will not be enough and the fruit will taste sour. In addition, the lack of pruning will lead to the fact that the tree will be very tall and harvesting will be difficult. When pruning large branches, breaks and tears are possible, leading to wounds that do not heal for a long time. Therefore, when pruning large branches, you should either support such a branch, or make a cut from below, and then cut it off completely. To prevent infection from getting into the wound, it is necessary to cover it with garden varnish. During the period of full fruiting, the amount of growth noticeably decreases, and with it the leaf surface. The tree produces less carbohydrates, which are used in large quantities to form the crop. And this in turn leads to a decrease in winter hardiness fruit trees.​

The formed crown should consist of one conductor and branches in tiers subordinate to each other, i.e. the branches of the first tier should be thicker and longer than the branches of the second, and, accordingly, the branches of the second should be thicker and longer than the branches of the third tier. Then shoots that compete with skeletal branches and branches are removed, as well as all strong branches growing inside the crown, intertwining or thickening it. Unwanted skeletal branches and shoots are cut to a developed lateral branch, and annual ones are cut to the outer bud (located with outside escape). This is necessary for horizontal growth of the next annual growths, stimulates the formation of flower buds and increases the yield of the branch.​

Early (summer) ripen in August. From this time, the consumption of fresh fruits continues until April - May at the expense of autumn varieties (consumer ripeness - September - November) and winter varieties suitable for long-term storage. Some varieties are stored until the next harvest. The fruits harmoniously combine sugars and acids, contain vitamins, mineral salts and other biologically active substances. Experts advise first of all to shorten the trunk by a third, and then thin out particularly dense areas.

​. In the first tier you can leave a branch at a height of 50 centimeters and two others (located above), but the distance between them should be 15 centimeters. One branch should go in one direction, and the other two should go in the opposite direction. Trim the ends of the branches at the same level. Take care to cut off the shoots that appear at the site where the central trunk was cut. You can leave the branches if their length is less than 30 centimeters, as they will definitely delight you with fruits.​ ​Pruning must be done correctly​After the tree has been formed, we continue to ensure that the subordination of the branches is maintained. To do this, shorten the increments. Increments of the continuation of skeletal branches are shortened by 1/4-1/5 of their length, and the leader should be 1/3 longer than other branches. Skeletal branches are trimmed so that their length is 1/2-2/3 of the length of the branch carrying them from the top to the place where the skeletal branch grows. Please note that you cannot cut annual growths short, as short pruning leads to strong branching of the branch and thickening of the crown, which delays the time the tree begins to bear fruit.​

​To the beginning​

Apple tree blossoms usually begin on May 15 - 20. In warm weather it lasts about a week, in hot, dry weather - less, and in cool or damp weather, it lasts up to two weeks. All varieties of this crop require cross pollination, so several varieties are planted in the garden.​​The pruning angle should be 45 degrees. For mandatory removal, it is recommended to remove shoots located at an acute angle to the trunk, since they most often break under the weight of apples.​ ​Prune the apple tree, leaving most of the skeleton.​

​and regularly, because subsequently significant difficulties may arise. Crown formation guarantees growth required quantity skeletal branches and their correct placement. In the future, new branches with leaves and fruits will appear at each branch, guaranteeing good development of the tree and a chance to enjoy amazing delicious fruits.​

​To do this, you need to promptly remove young top shoots, which inevitably grow near the places where large branches are removed and annual growths are bent. All tops that arise after formation are cut out. At the end, a final check of the subordination of all continuation shoots is carried out and the formed crown of the fruit-bearing tree is assessed. By pruning you need to lay down the crown and ensure the subordination of the branches. However, the formation of the crown takes several years until a natural slowdown in growth occurs due to the transfer of vegetative branches to fruiting ones. In the current season, it will be necessary to: promptly remove young fatty (top) shoots, which inevitably grow near the places where large branches are removed, and bend back annual growths to transfer them to fruiting.​

​Back​​Growth buds formed on a shoot behave differently under natural conditions: in the upper part they give strong growths, a little lower - weaker ones, even lower - short ringlets and leaves, and at the base of the shoot they generally remain dormant. But after pruning or bending the branches, strong shoots can grow from weaker and even dormant buds that find themselves in the upper position.​ ​Rejuvenating procedures for an apple tree are carried out closer to spring, but until the tree has no leaves and is at rest .​

When the first branches sprout on the main shoot, the first row is created in the middle of the trunk, deviating the central parts.

Spindle-shaped crown

​Weakened branches lose strength and break from strong gusts of wind. Freezing of apple trees with a large number of branches weakens the wood. This is typical for a variety like Borovinka. For the same reason, the emergence of main branches at an acute angle is observed. This problem occurs in apple trees of the Terentyevka variety.​ ​Crown diameter decreases​​The most popular way.​

​. Pruning of apple tree branches will be minimal. Take into account that the central conductor must be cut correctly, and semi-skeletal branches can be trimmed with pruning shears. It will take about three years to create a crown. The first fruits can be obtained in the second year. Apple trees should be located at a distance of two meters from each other.​

​equalize with each other​​You should start pruning a year after you planted the apple tree in the spring. Be prepared for the fact that young seedlings have a weak root system, due to which the crown can be shortened only by a third when the seedling is about 60 centimeters high, and by half when the height is 60 centimeters or more. If the height of the seedling is less than 60 centimeters, only the lower branches can be trimmed. Remember that the main conductor should be 40 - 50 cm higher than the skeletal branches of the apple tree. Prepare for the fact that the formation will need to be carried out annually. You can ensure good growth of side branches if you trim the crown branches​ ​Fig. 7. Cut to the kidney (a - cut; b - result):​

The main methods of forming the crown of an apple tree

​First of all, get rid of the upper branches.​

It is important to know

​The next season the frame is cut off again.​

​Special techniques and types of pruning allow for maximum penetration natural light into the thickness of the leaves. Since the apple tree needs intense sunlight for rapid growth and proper development, allowing you to get the fruits as early as possible. Typically, fruiting occurs a year or two earlier by removing not the competing shoot, but the leading shoot, which is the main shoot in terms of growth power. It is very important to pinch out developing shoots that compete in growth strength with the leaders. In the future, such escapes in spring period are completely removed.​

The demand for this method is due to the maximum naturalness of the tree’s silhouette. The branches are cut in tiers. A feature of the method is to increase the productivity of the apple tree and prolong the fruiting period. To use this method, the location of plants in garden plantings must be at a distance of at least three meters.​

Why is it necessary to form a crown?

A prerequisite is the presence of a central conductor with semi-skeletal branches extending in different directions. One-year-old seedlings can be processed. Competitors must be eliminated. The growth of the central conductor, which exceeds the end of the main branches, must be shortened.​

​approximately a quarter of the growth length​

  • ​1 - the cut is made correctly;​​2​
  • Apple trees are planted in spring (late April - mid-May) and autumn (September - first ten days of October). At autumn planting Leaves are carefully removed from apple tree seedlings. With a well-developed fibrous root system, seedlings quickly take root. When transporting them to the planting site, the roots are dipped in a creamy clay mash and wrapped in film or burlap. Before planting an apple tree, dried seedlings are immersed in water for one to two days. In the spring, when the weather is dry and windy, after planting, the stems are wrapped in a damp cloth or moss. This reduces the desiccation of the tissues of the seedling.​ ​This is done for better conductivity of sunlight to the lower parts, and, therefore, their productivity increases.​

​At the end of the third season, the creation of the “spindle” is completed.​

The quality of apples also depends on the shape of the apple tree. Instead of wasting nutrients on branches and leaves, some of the necessary elements go to the development of fruits. Thus, sugar produced during photosynthesis accumulates directly in apples.​ ​Crown diameter increases,​​This method is characterized by speed and ease of implementation.​

​In an area with a groundwater depth of no closer than 1.5 m, the apple tree is planted in planting holes 100 cm wide and 60 cm deep. For an apple tree on a dwarf rootstock, a hole or trench is dug smaller - 40 - 50 cm. On sandy or uncultivated poor soils, their size more. This is done in order to bring in more good fertile soil. And on heavy ones clay soils The holes are made wider, but somewhat shallower, since water can stagnate at the bottom of deep holes with heavy soil and cause rotting of the roots. WITH top layer Fertilizers are mixed with soil taken out of the hole. Fresh, unrotted manure cannot be used for filling pits.​

Formation of a vertical palmette

​It is necessary to form a reliable structure so that the fragile tree can withstand the significant weight of a large number of apples. This point is especially important for apple orchards in open, unprotected areas, which is associated with insufficient removal and thinning. By the autumn period of the first year, seedlings should have four main skeletal shoots, the length of which is about fifty centimeters. A small amount of shoots is subject to processing or pruning. The most important thing is to properly trim the frame of the conducting branch. The main shoots are removed using pruning shears.​

​Removing the stem is not so important for certain types of apple trees, since the formation of their lateral shoots occurs faster. In this case, if the trunk grows by 50 cm over the season, it is shortened to symmetrically grow new branches.​

​Dense foliage makes it easier for pests to settle in and can damage the tree bark.​

​Complete non-interference in the development of a fruit tree is also unacceptable. This leads to the crown of the apple tree becoming too voluminous and dense.​

Good illumination of all parts of the crown plays a significant role in increasing the productivity of a fruit tree. To do this, it is formed and thinned out during the fruiting period. This work is usually done by trimming. But pruning associated with the formation of the crown deprives the trees of early fruiting. The desire to obtain an early commercial harvest leads to the need to reduce the degree and duration of the pruning period. At the same time, the burden of young trees with harvest leads to premature aging and a shortening of the life span of fruit trees. Accelerating the fruiting of young trees is facilitated not only by reducing the amount of pruning during the period of crown formation, but also by using techniques such as pinching, breaking, twisting, bending and intertwining branches. With the onset of sustainable fruiting, pruning is intensified in order to maintain the active growth of the tree, and therefore increase its productive period.​

​Crown formation is most often carried out in the spring.​

  • ​Formation of the crown is an important measure for caring for apple trees. One of the most important measures for caring for fruit trees, including apple trees, is the formation of the crown. It is very important to carry out the procedure in accordance with a certain algorithm, which allows you to form a structure, create the correct shape and the required volume of foliage of the fruit tree.​

​Three branches of the first tier should be directed towards different sides. The divergence angle between them should be approximately 120 degrees. Each of them should be cut 40 centimeters from the central conductor, due to which paired branches will be obtained. The center conductor should be shortened above the top branch. If desired, it can be shortened after 1 - 2 years in order to give optimal strength to the frame.​

​If you are interested in how to carry out the upcoming procedure, it is very important to watch an informative video containing answers to all your questions.

In the first year it grew from a seed (or from a cutting), in the second year it took a graft, and in the third year a yearling grew on it. In early spring, measure 50 cm from the soil level on the tree. This will be the trunk zone. It is undesirable to have a trunk less than 50 cm, since subsequently the lower branches will interfere with caring for the garden: digging or loosening the soil, mowing the grass in gardens with turf, applying fertilizers, collecting wood fallen, trimming branches. It is dangerous to leave a very high trunk in the middle zone. He will suffer greatly from sunburn and frost damage. So 50 cm, as practice has shown, is the best option.​

The reason for this is the appearance of many new shoots that need to be thinned out, and the remaining ones need to be spread in the required directions.

​You've probably noticed the difference between apple trees in an old private garden and farm fruit tree plantations. Most often, one or two mighty trees grow on the site. While on commercial sites the plants are not tall and they are all the same shape, as if they were a carbon copy.​

  • ​that illiterate pruning can cause more damage to the plantings than the complete lack of formation of the crown of the apple tree.​
  • ​. To do this, cut off the branches of the main branches.​
  • ​In our time, formation can be carried out according to the following principles:​

​located above, cut above a well-developed bud, which, when viewed vertically, is located exactly above the place where the thorn is cut. This is done so that the trunk does not deviate from the vertical position. If you make the cut with a garden knife, then place it with reverse side buds at an angle of 30 degrees to the horizontal and cut the branch with a sharp movement towards you. You cannot leave a stump above the bud, otherwise the shoot may deviate greatly to the side. But you can’t cut its base either: it will dry out, and the shoot will grow from another bud and go completely in the wrong direction in which the central conductor should grow (Fig. 7). If you are not sure that you will get a good cut above the bud, leave another 10 cm over the measured ones. This will be the thorn to which you will tie the shoot when it reaches a length of 10-12 cm (Fig. 8). In the summer, take a closer look: have the shoots on the thorn from the dormant buds begun to grow? If you find them, break them out; the tree does not need them. By the way, look to see if there are any shoots in the trunk area. If there are any, pinch them above the 3-4th leaf. After pinching, they will not grow much, and their leaves will contribute to the thickening of the trunk and better growth of shoots in the branching zone. In the spring of next year, remove all the branches on the trunk, if they suddenly appear again. In the main branch placement area, select three. The lowest one should be at the height of the trunk (50 cm), and the other two are higher along the trunk at intervals of 15 cm. A little more, a little less - it doesn’t matter. It is important that the main branches are not crowded. One of them should be directed in one direction, and the other two should be directed in the opposite direction. The optimal divergence angle between the main branches is 120 degrees. Cut out one or two branches closest to the place where the stem was cut last year. These are competitors. They extend from the central conductor at an acute (less than 40 degrees) angle and grow as strongly as the branch with which the crown grows in height. They are not suitable as main branches, since they constantly threaten to break. Also cut out other strong branches that are not part of the skeleton. Make the cut at their very base, where there is usually an annular influx. Hence the term among gardeners - cut into a ring. By the way, in the annular influx there are a lot of cells capable of active division, which contributes to better and faster healing of wounds. However, if you prefer, you can bend them to a horizontal or drooping position. Let them work on the plant temporarily. You look, and the beginning of fruiting will accelerate. And you will always have time to cut them out. In addition, horizontally located branches will not grow much (Fig. 9.2-3).

​. When shortening, part of the annual growth or perennial branch is removed. This pruning method has different effects on trees depending on their age. In young trees, when annual growths are repeatedly shortened, the growth of the cut branch in length is weakened, but its branching increases, which is used in the formation of the crown. Shortening the branches of aging trees increases the number of annual growths, their length, and, consequently, the number of large, healthy leaves. By shortening, you can also change the direction of branch growth. When thinning, part or all of the branch is removed at the base.

However, there are also opponents of summer pruning.

​Pruning of pome crops begins in late February - early March, when the danger has passed severe frosts and the temperature will not drop below -2-4 °C. At lower temperatures, the wood of fruit trees becomes brittle, the cuts are uneven and traumatic, the bark breaks off, leaving defenseless bare trunks open to sunburn and pests. Therefore, even in the beginning - mid-February, while walking around the garden, it is worth determining what kind of pruning each tree needs.​

​Depending on the varieties and growing conditions, each gardening zone has its own crown shapes.​

​Features of anti-aging pruning:​​. It will take about four years to form. After this period, the tree will delight you with tasty fruits and productivity. ​spindle-shaped.​​4 - fully formed crown

​A large number of competitors for nutrients and the sun of the branches must be limited so that the subordination of the branches of the first and subsequent orders is not violated. If this is not done, excessive vegetative mass is formed to the detriment of the formation of flower buds and the yield is reduced. Due to the lack of light in the inner zone of such a crown, the fruiting branches die off early, and few flower buds are formed on the remaining ones. Almost no ovaries are formed. Inside the thickened crown, conditions are created for the development of pests and diseases, since the penetration of sunlight into it is difficult, ventilation is limited, and treatment with supporting, nutritional and protective preparations does not have an effect.

​The following crowns can be used for standard trees: sparsely-tiered, vertical palmette, spindle-shaped. Many gardeners allow a free-growing crown, that is, they leave it without formation.
During this period, you can get rid of the shoots growing along the frame.
​The levels are formed symmetrically vertically and have a distance of 85 cm.​
​After 10 months, the shoots formed in the trunk are cut off. In a row, a shoot is kept at a distance of 30 cm, and then - two, with a distance of 20. The principle of the method is the mirror arrangement of branches. Often the condensation of a tree is due to the fact that in frosts the base trunk dies and intensive development of lateral shoots begins, with over time turning into the main conductors.​
​Helps restore productivity and allows you to increase fruiting time while maintaining the size and taste of the fruit.​

​Dense garden plantings can cause diseases​

Skeletal branches should be placed in the same plane. As a result, the crown will be flat. In each tier that is part of the central conductor, you will need to leave two branches, but they should grow in opposite directions from each other. The distance between tiers should be 80 centimeters.​
​What features should be taken into account?​
​Do not cut, bend or shorten branches shorter than 30 cm. Leave them alone. And in the future, for any

The development of the crown of such a tree goes up due to the mass of shoots, the vertical direction of which stimulates the formation of new vegetative shoots devoid of flower buds. In such a crown there are no conditions for the growth of horizontal shoots on which flower buds are laid that ensure the harvest. In addition, the rapid upward growth of a tree leads to the formation of sharp angles between the branches, which carries the risk of branches breaking and breaking off from the trunk under increased loads. The greater the angle of departure of the branch, the better its fusion with the trunk or branch of the previous order.

  • Never touch such branches when pruning, except in special cases. The fact is that most short branches are more prone to fruiting than to growth. Unfortunately, many gardeners do not know this and cut out such branches with the firm confidence that they are doing a good and very necessary thing for the trees. But in fact it is difficult to imagine anything more ridiculous. It's painful to look at trees trimmed into half-boxes. The three main branches that were left will require a little more work. So that none of them overtakes the others in growth, they must be placed in an equal position. Trim their ends at approximately the same level. Or, instead of pruning, you can slightly bend the longer branch downwards and pull the shorter one up. If after this the ends of the branches are not at the same level, you will have to shorten the strongest one slightly. By the way, the central conductor throughout the entire period of crown formation should be higher than the ends of the main branches in plants with pyramidal growth by 15-20, with spreading ones - by 10-15 cm. Next year, lay two more main branches 50-60 cm above the branches of the first tier. The interval between them is 10-15 cm. As last year, equalize them with each other. Be sure to cut out competitors and shorten the conductor's last year's growth if it ends up much higher than the ends of the newly abandoned main branches. Those of them that last year were bent to a horizontal or drooping position, if they do not interfere, leave them alone, and if they thicken the crown, shorten them further or cut them into a ring. A year later, lay another one 40 cm above the two branches of the second tier main branch (Fig. 9.4). You can assume that the skeleton of the crown is formed. After a year or two, when the upper single branch takes a stable position, cut off the central conductor above it. A further increase in crown height is undesirable; the optimal is 2.5-3 m. It should be kept at this level.​
  • There are many ways to prune fruit trees, depending on the rootstock (vigorous, medium-growing, dwarf), growing area and corresponding technologies. The most common method is to prune fruit trees using a sparsely tiered system, when the skeletal branches are arranged in tiers on top of each other. Priority crops that lend themselves well to pruning using this system are apple and pear.​
​. The skeleton (skeleton) of a tree is formed from a conductor and three to four skeletal branches of the first order. They are placed on the conductor in tiers or individually. There can be no more than two branches in the lower tier. The distance between tiers and single skeletal branches on the conductor is 40 - 60 cm.​

​This does not in any way affect the amount of the future harvest.​

​Basic branches should be tightened if they have noticeably moved away from the head part. If the processes have not deviated enough, then, on the contrary, they are pulled back.

Crown lightening

​The formation of the crown is carried out in the initial 5-7 years of the life of the fruit plant. Such a tree must have one conductor. Therefore, the most powerful, developed shoot of the continuation of the conductor is selected and left, the rest are removed.

The crown skeleton will be strong if the branches are strong and subordinate to the conductor (that is, the ends of all branches are 20 - 25 cm below the conductor); the diameter of the skeletal branches at their base will not exceed half the diameter of the conductor at the point of their connection; the angle between these branches and the conductor (divergence angle) will be 45 - 60°; all skeletal branches are evenly located in space, that is, the angle of “divergence” between two adjacent branches can be within limits. 90 - 150°.​

Moreover, the autumn method perfectly prepares the apple tree for wintering, freeing the tree from dried, large or non-fruit-bearing branches.

What should the crown be like?

With this form, the tree grows in length according to the number of rows. It is possible to adjust the value when pruning the base shoots and trunk annually. Growth over 12 months is shortened by a small distance. Horizontally the tree grows by about two hundred centimeters.​

​The picture shows a young apple tree, the crown of which is formed according to a sparsely layered system, before formative spring pruning. Before the trees enter the fruiting season, formative pruning is carried out. Remove competitors on the central conductor, vertical branches near the skeletal branches. Sharp forks are transferred to the lateral branch. Vertically growing branches on the periphery of the crown are cut to a side branch, horizontal if possible. They form tiers in which the skeletal branches are subordinate. The upper tier of branches is subordinated to the lower one, approximately 30-50 cm shorter. The central conductor should be 25-30 cm above the upper tier of the side branches.​

​Thus, all options for crown formation come down to ensuring the correct balance of the growth force of the base conductor and the main branches growing from it.​

​An amazing feature of the apple tree is its almost eternal ability to produce a harvest. Although, the intensity of fruiting decreases noticeably over the years.

​The main shoots can be removed with improvised tools, using, for example, pruning shears, since the precision of the cut is not fundamentally important in this case.​

​Rejuvenation by pruning is carried out in the spring, but when the fruit plant is dormant.​
​Usage special equipment and different pruning methods allows you to thin out the foliage of the crown as much as possible and ensure high-quality penetration of sunlight to all parts of the tree. An apple growing on a sparse branch ripens much faster and has best performance quality.​
​Height can be adjusted​
​Formation should begin by measuring the trunk zone on an annual seedling. Keep in mind that the rootstock can be three years old, but the grafted shoot must be one year old. The distance from the ground should be approximately 50 centimeters. Above the measured area of ​​the trunk, you should mark an additional 30 centimeters, where the three main branches belonging to the first tier will be located. Branches growing higher should be cut off.​

​Kudryavets R.P.​

From the age of 5-6 years, most varieties begin to bear fruit. The crown thickens and fruiting shifts to the periphery. To prevent this, you need to start lightening the crown. We leave the central conductor, and cut out the competitors “into a ring,” that is, at the base of the branch growth. On the left conductor, developed skeletal branches are selected and combined into groups by height, which will form the first, second, and, if necessary, the third tier. The distance between the first and second tier is maintained at about 60-80 cm, between the second and third - 30-40 cm. The branches forming the second tier are spread along the diameter of the trunk relative to the first, the branches forming the third tier - relative to the second. I cut out branches that are not included in the tiers “into a ring.” The tree trunk is left 80 cm high.

To ensure that all parts of the apple tree crown are well illuminated, it is systematically thinned out, maintaining the subordination of the skeletal branches to the conductor. Narrow, pyramidal crowns are expanded by pruning skeletal branches into external growths. In spreading (wide) crowns, the growth of skeletal branches is directed upward, cutting them into branches with a more vertical position in the crown. At the ends of the branches, the forks formed from two equally developed growths are eliminated. To prevent them from breaking in the future, one of them is removed.​

​It is obvious that the central conductor should be higher, stronger and more powerful than the processes. When the branches grow to the same level as the conductors, shortening is carried out. The long-lived apple tree is preserved by all owners possible ways, one of which is pruning. There is an opinion that it is more advisable to remove the old tree, replacing it with young seedlings of new varieties. If there is a desire to leave an old apple tree, then this is done by forming the main structure of the branches. Formation of the crown of an apple tree

The formation system should be understood as the creation of a crown of a certain habit and structure using pruning or other techniques for regulating plant growth. Each system is characterized by the shape of the crown, the height of the trunk, the presence or absence of a conductor, the number and placement on the trunk and in space of skeletal branches of the first and second orders of branching, as well as methods of regulating plant growth used during formation.

In the gardens with large areas feeding and when trees stand freely, a sparsely layered formation system is widespread (Fig. 43). Its main feature is the tiered and single placement of skeletal branches of the first order, as well as the possibility of choosing different patterns for their placement on the trunk.

The height of the trunk is 50-70 cm, the crown is formed from five to six branches of the first order. Possible the following options their placement: the lower tier of two branches, the upper three separately; two tiers of two branches, the top two singly; lower tier of three branches, three upper branches singly; the lower tier of three, the second of two, the two upper branches singly. For the strength of the crown, it is necessary that there be no less than the number of branches above the tier of single branches than the number of branches in the tier. The guidewire is removed above the last lateral branch.

To ensure a good light regime in the crown, it is important to maintain certain distances between the skeletal branches. Between two two-legged tiers, for varieties with a spreading crown, the distance should be 60-80 cm, and with a pyramidal one - 80-100 cm. If a single branch above a two-legged tier is directed towards a large free gap between the lower branches, then the distance to this branch may be small (25-50 cm). The intervals between single branches for varieties with a pyramidal crown should be 80-100 cm, and for varieties with a spreading crown - 60-80 cm.

Skeletal branches of the second order are possible only in the lower tier, no more than two on the skeletal branch of the first order of branching. They are placed at a distance of 40-50 cm from each other. Thus, the total number of skeletal branches in the crown should be no more than 12. All other branches are formed as semi-skeletal branches 1-1.5 m long. They are placed in groups of two or three with distances between adjacent groups of 40-80 cm. Tree growth is limited at height 3.5-4 m.

The sparse-tiered formation system is the least patterned and corresponds well to the natural patterns of crown composition in most breeds.

Whorled-tiered. Skeletal branches of the first order (8-12) are placed in tiers: in the lower tier there are usually five, and in subsequent ones there are three or four branches. In production conditions, two tiers are usually laid, after which the conductor is cut out or it develops freely (in most varieties of apple trees, it deviates with age and takes the position of a side branch).

The branches of the first tier are placed as evenly as possible around the trunk, and the branches of the second - in the spaces between the branches of the first tier. The distance between adjacent tiers is 90-100 cm. On the branches of the first order of the first tier, two or three skeletal branches of the second order are formed: the first at a distance of 50-60 cm from the trunk, and the subsequent ones with an interval of 35-40 cm. On the branches of the second order, each one or two skeletal branches of the third order with an interval of 30-40 cm. To improve the illumination of the crown, in the second tier (as well as in the third, if there is one) only semi-skeletal branches with a length of no more than 150 cm are formed on the branches of the first order.

In the first half of the century, this system prevailed in industrial plantings of apple and pear trees, which is explained by the simplicity and speed of completion of formation. However, the crown turns out to be fragile in the places where the skeletal branches depart from the trunk, becomes very thick and has other design flaws. Therefore, this system has now been replaced by a more advanced one.

Changed-leader(sparse, tiered) crown. Five to six skeletal branches of the first order are placed on the trunk singly at intervals of 25-40 cm, the conductor is removed above the last lateral branch. Skeletal branches of the second order are laid on the branches of the first order, two or three at intervals of 35-50 cm.

Despite the strength and favorable light conditions, this type of crown is not widely used due to the large amount of pruning, the length of the formation period, the later entry of trees into fruiting and the slow increase in yield.

Vase-shaped, cup-shaped, cauldron-shaped crown is used mainly on peach. The conductor is removed above the first tier of three to five branches formed from adjacent buds. Pruning is used to achieve bifurcation of skeletal branches to ever increasing orders.

Improved vase-shaped crown. Three skeletal branches from adjacent buds are laid in a tier, or better at intervals of 25-40 cm. Two or three skeletal branches are placed on them with distances of 35-50 cm. The branches of subsequent branching orders are semi-skeletal and overgrowing. The crown center is constantly maintained in open state. The crown has good light conditions, but is not strong enough.

Lobed crown of A. A. Ilyinsky has two or three four-legged tiers. Branches in tiers are laid in pairs from adjacent opposite buds, the distance between pairs is 15-20 cm, divergence angles are about 90° (cross placement of branches). The branches of the second and third tiers are placed above the branches of the first tier, as a result of which four vertical planes. The distance between tiers is 60-100 cm. 30-50 cm above the last tier, the conductor is cut out above a single side branch. The interlobular space at the periphery of the crown, about 1 m wide, ends about a meter from the trunk and has a width of 0.6-0.7 m in this part.

The crown has a good light regime and is convenient for picking fruits. Currently being tested under production conditions in eastern Ukraine and the North Caucasus.

Channel-fan system formation by N.P. Donskikh (Fig. 44) is used in gardens with wide row spacing (6 m or more) and close placement of trees in rows (3-4 m). The crown is formed from five to six branches of the first order. They are placed on the trunk according to the principle of a sparse-tiered system, i.e., in tiers and singly. The significant difference is that the branches are directed only towards the row spacing: the lower four at an angle of approximately 45° to the row line, and the upper one or two at an angle of 90°. The trees in a row quickly close together and form a solid wall, so only semi-skeletal branches form along the row. The conductor is removed above the last side branch, thereby creating a light channel along the row, free of branches and providing good illumination within the crown. For machine operation and tree care, a free space of 2-2.5 m wide is left between the rows, and 0.5-0.6 m wide between adjacent plants in the row.

The channel-fan formation system has become widespread in connection with the transition to dense planting of trees in rows. However, it has a number of significant disadvantages: the rapid closing of crowns in rows and their large width, which make harvesting difficult, a significant amount of manual pruning when creating and maintaining free spaces between trees in rows, the use of pruning machines mainly only when limiting the height of trees, etc.

The vertical-plane formation system was developed by N.P. Donskikh for plantings on seed rootstocks with tree planting patterns of 5 × 4-5, 4 × 4-5 m. Five to six skeletal branches of the first order are placed on the trunk according to the principle of a sparse-tiered crown, but the four lower ones are directed at an angle of 35-45° to the axis of the row, and one or two upper ones are directed along the axis of the row (Fig. 45). After the plants begin to close in the rows, contour pruning is carried out, leaving a free space 2-2.5 m wide, as a result of which the width of the wall along the row is 3-2.5 m (planting pattern 5 × 5 m), the height of the wall is 4-4 .5 m.

In plantings of this design, there are great opportunities for the use of pruning machines, labor productivity in harvesting fruits, the effectiveness of measures to combat diseases and pests are significantly increased, the yield reaches 400-550 quintals per 1 ha. Currently, plantings of this type are being tested in production conditions.

The tasks of forming freely growing trees in plantings with dense placement of trees in rows and increased planting density (5 × 5 m, etc.) include increasing the strength of trees, creating good illumination inside the crown during the entire period of production use of plantings, limiting the volume of the crown to increase labor productivity in plant care work, the effectiveness of measures to combat diseases and pests, creating conditions for machine pruning, etc. The strength of the crown can be significantly increased if a number of rules are followed during formation:

1. The skeletal branches must have good subordination, that is, the correct ratio in the strength of development between the supporting branches and the branches extending from them: the conductor must prevail over the branches of the first order, the latter over the branches of the second order, etc.

With good subordination, the diameter of the side branch should be 0.4-0.6 of the diameter of the supporting branch below the side branch. With a smaller diameter, the lateral branch lags behind in growth and cannot become a full-fledged skeletal branch; with a larger diameter, the strength of the connection with the supporting branch weakens and there is a danger of fracture. The intensity of branch growth is regulated by appropriate pruning or changing the slope of the lateral branch.

2. Regulation of the subordination of lateral branches to the conductor becomes more difficult with an increase in their number in the tier. Therefore, a tier should be created from no more than three branches with divergence angles of at least 90°, if these branches are formed from adjacent buds.

3. Only those branches with angles of departure of at least 40° and no more than 80° can be selected as skeletal branches. At branching angles of less than 40°, the bark tissues are pinched by the thickening branches and die off; as a result, the formation of continuous layers of wood stops and the mechanical connection with the supporting branch is provided only in the lower part of the branch (Fig. 46). In addition, branches with sharp angles of departure very easily fall out of alignment, and this increases the risk of fracture. Therefore, branches with sharp corners must be removed at a young age.

At angles of departure of more than 80-90°, the branches lag behind in growth and it is difficult to form full-fledged skeletal branches from them. Consequently, optimal conditions for the formation of full-fledged skeletal branches are created at angles of divergence of 45-65°.

4. To create a favorable light regime in the crown, the following conditions are observed. The number of skeletal branches of the first and second orders is strictly normalized in accordance with the adopted formation system. Skeletal branches are placed in space so that each has its own sector in the crown, and the crown as a whole represents the most rational and highly productive optical system. Strictly maintain the intervals between adjacent skeletal branches established by the formation system. 2-3 years after the laying of the last skeletal branch, when it takes a stable spatial position, the conductor and large branches shading the center of the crown are cut out, and then constantly maintain sufficient light transmission of the crown by thinning.

5. Limiting the volume of the crown is of great production importance, since with increasing size, labor productivity in caring for plants and collecting fruits, as well as the effectiveness of measures to combat diseases and pests decrease due to a decrease in the quality of treatment of all parts of the crown with pesticides. For these reasons, the size of the crowns of an apple tree should not exceed 5-6 m in diameter and 3.5-4 m in height; for a pear tree - 5-6 and 4-4.5 m, respectively.

Pruning apple and pear trees.First pruning after planting the garden. It has been established that pruning trees in the first year after planting weakens the plants, delaying the onset of regrowth and root development. Therefore, next year trees without pruning develop better than with pruning. But this pattern is observed only in conditions of a cool and humid spring or with timely and abundant watering.

In conditions of a dry and hot spring and insufficient soil moisture, the early blooming of apical buds increases the risk of drying out and death of plants. Their removal during pruning delays the formation of leaves by 5-7 days and thereby increases the survival rate of trees. Therefore, in areas of sufficient moisture, the first pruning is carried out in the spring after a year, and in areas of insufficient moisture - in the spring after planting.

During the first pruning, the crown formation that began in the nursery continues. Since branches may be damaged during digging and transportation, nurseries produce seedlings with five to eight branches, i.e., with more than is needed to form the lower tier. Therefore, one of the main tasks of the first pruning is to select good skeletal branches in accordance with the requirements of the adopted formation system. Competitive branches with sharp angles of departure are cut out, since it is usually not possible to suppress them with strong pruning. All strong excess branches are weakened by pruning or bent to a horizontal position to transform them into semi-skeletal or overgrowing branches. The second task is to equalize the strength of the development of future skeletal branches, subordinate them to the conductor, and also to obtain lateral branches closer to the base of the branches. To do this, the branch with the average strength is shortened by about 1/3, and all the rest are trimmed so that the ends of the branches are at approximately the same level: the upper branches are stronger and the lower ones are weaker. The conductor in varieties with a pyramidal crown type should exceed the lateral branches by 20-25 cm, and in varieties with a spreading crown - by 10-15 cm (Fig. 47).

When shortening, the desired direction is simultaneously given to future shoots of continuation, which is achieved the right choice position of the remaining upper kidney.

In varieties with a pyramidal crown, the cut is made above the outer bud in order to deflect the branch and thereby expand the crown, and in varieties with a spreading crown, the cut is made above the inner bud to make the crown more compact and prevent the branches from sagging.

Pruning during growth period. The main task of pruning in this age period is the formation of the crown. Regular annual pruning begins a year after the first post-planting pruning. If pruning is carried out irregularly, then it is forcedly strong, since any growth shoot with intensive growth turns into a large branch after 2-3 years. When removing overgrown branches, many large wounds remain on the tree, the risk of wood infection increases, and labor costs for pruning increase by 3-5 times. The approximate cutting order is as follows:

1. Remove emerging competitors and branches with very sharp corners, since it is usually not possible to weaken their growth by pruning or bending.

2. The next skeletal branches of the first order are selected in accordance with the adopted formation system.

3. On the first-order branches of the lower tier, second-order branches are selected. For this, lateral branches are most suitable, and not branches that have developed on the inside of the skeletal branch of the first order, since they grow inside the crown and will thicken it. Cut them into a ring. Branches developed from external buds (on the outside of the branch) are also unsuitable as second-order skeletal branches (they easily droop under the weight of the harvest and often break off).

4. All other strongly growing branches are converted into overgrown or semi-skeletal branches by pruning or bending. Strong branches, if they occupy a position close to horizontal, as well as weak growths shorter than 20-25 cm, do not weaken. The growth of such branches is restrained; fruiting soon begins on them, and without pruning they turn into semi-skeletal ones.

5. The skeletal branches of the first order are subordinated to the conductor, and the skeletal branches of the second order are subordinated to the branches of the first order (should be approximately at the same level). The height of the conductor should be 20-25 cm for varieties with a compressed crown and 10-15 cm for varieties with a spreading crown. The ends of the first-order branches should have approximately the same excess over the second-order branches (Fig. 48).

When forming young trees, it is important to create strong skeletal branches covered along the entire length with lateral branches. The formation of thin bare skeletal branches, which do not thicken well and easily sag with the onset of fruiting, should not be allowed. To avoid this, the growths are shortened. In this case, you need to correctly set the degree of shortening. A very weak pruning does not give the desired effect, an excessively strong one leads to a thickening of the crown and the need for severe thinning pruning in subsequent years, which inevitably weakens the trees and delays the onset of their fruiting.

To determine the optimal degree of shortening, the length of annual branches, their position in the crown and varietal characteristics of bud awakening and shoot production ability are taken into account. Annual growths of less than 40 cm are not shortened to increase bud viability; with a length of 40-60 cm, the shortening should be weak, and with a length of more than 60 cm - medium or strong.

In varieties with good bud awakening and good shoot-producing ability, annual branches are pruned slightly, removing only the ends with immature wood and weak buds. More intensive shortening leads to thickening of the crown.

In varieties with high or average bud arousability, but with average or weak shoot production ability, the annual branches are shortened by 1/4-1/3. With this shortening, instead of weak, short-lived ringlets, stronger mixed fruit-bearing branches develop along the entire length (Fig. 49).

In varieties with poor bud awakening and poor shoot production ability (such as Cinnamon Striped), increasing the degree of shortening does not give the desired effect. It is used only in the first 4-5 years to obtain stable skeletal branches and to establish strong lateral branches at their base.

In subsequent years, lateral branch pruning is used to enhance branching. The essence of this pruning method is shown in Figure 50. When the entire annual branch and a small part of the two-year growth above the upper lateral branch are removed, the awakening of the buds and the growth of lateral branches are enhanced both below and above the cut site.

The degree of shortening of the annual branches may be more severe than is necessary to enhance the awakening of the buds. In particular, the need for such pruning often arises in connection with the need to subordinate, change the direction or equalize the growth force of branches.

Young plants produce many strong shoots every year. As a result, if their growth is not regulated, much more skeletal branches are formed than is necessary to create a full-fledged crown.

Vertically growing excess branches, which are difficult to turn into semi-skeletal ones by pruning, must be cut into a ring. With a large slope, it is relatively easy to turn strong branches into semi-skeletal and overgrown branches with appropriate pruning. The technique of such pruning is shown in Figure 51. In the first year, the annual branch is greatly shortened, leaving four to eight well-developed buds. After such pruning, several strong shoots develop from the upper buds, and overgrowing branches from the lower ones. The next year, the branch is cut off above the lower, obliquely located branch of the growth type, and the remaining branch is slightly shortened. Similar pruning is carried out in the 3rd year. After 2-3 years the branch begins to bear fruit.

Heavy pruning weakens the growth of young trees, delays their entry into fruiting, and reduces the rate of yield growth. In the last 10-15 years, the feasibility of minimal pruning of trees in the first and second age periods has been established. Pruning should be carried out only to subordinate the branches, to prevent the formation of a large bare zone in the lower parts of strong annual growths, to enhance the growth of ringlets in varieties with high bud vigor and to establish new skeletal and semi-skeletal branches of the first order. In this case, shortening pruning is replaced by changing the angle of inclination of the branches, installing spacers, gartering or deformation.

Only competing branches with sharp angles of departure, the growth of which is difficult to weaken by pruning and other techniques, as well as strongly thickening branches, are cut out. All others are bent to a horizontal position.

Pruning during growth and fruiting period. In this age period, the formation of the crown is completed: the last skeletal branches of the first order are selected, and in the lower tier - the skeletal branches of the second order; after 3-4 years, the conductor is removed above the upper skeletal branch and the subordination of the branches is constantly maintained.

To prevent thickening of the crown, special attention is paid to pruning the peripheral part, since here the growth of shoots is still intense and unnecessary strong branches may appear. The growth of semi-skeletal branches is carefully regulated so that their length does not exceed 1 m.

Before removing the conductor, the degree of its excess over the endings of the skeletal branches of the lower tier is increased to 60-80 cm. The endings of the remaining skeletal branches of the first order occupy an intermediate position. If the difference in the height of the ends of the skeletal branches of the first and second orders is brought to 40-60 cm, then shortening is carried out only to subordinate the branches. After removing the conductor, the height of the tree is limited to 3.5-4 m, for which the growth of skeletal branches is directed towards the row spacing by pruning to the outer side branches.

Pruning during fruiting period. The main purpose of pruning in this age period is to restore and maintain sufficient high level the intensity of plant growth, as well as reducing the excess number of fruiting points. This is achieved through rejuvenation and detailed pruning.

Anti-aging pruning - shortening perennial branches to 3-5 year old and older parts. Its degree depends on the condition of the plants. If the length of annual growths has decreased to 10-20 cm, light pruning is carried out (on 2-3-year-old parts of branches), and if the growth is even weaker, the pruning is intensified. When determining the degree of pruning, they are guided by the following rule: pruned to that part of the branch where the length of the annual growth was at least 40 cm. Weaker pruning does not give the desired results. All skeletal and semi-skeletal branches are rejuvenated. The reaction of plants to pruning, gradually weakening, persists for 3-4 years, after which it is repeated.

During detailed pruning, the overgrowing branches are additionally shortened: mixed fruit-bearing branches more than 25 cm long to half their length, and from V3 to V2 branches of fruit-bearing branches are removed. Some of the old fruit-bearing branches deep in the crown and in dense places are cut out for thinning (Fig. 52).

Reduced tree height. In tall trees (more than 4.5 m), the fruiting zone is usually 1.5-2 m and is located on the periphery of the crown; the unproductive inner zone occupies up to 50% of the total volume. The costs of garden care, especially harvesting and pruning, increase sharply as the height increases, and the effectiveness of protective measures and the quality of the fruit decrease. Therefore, for plants on seed rootstocks, the optimal height is 3.5-4.5 m. If for some reason the height was not limited during formation, it must be reduced without further delay.

A sharp one-time reduction with the removal of a large number of fruit-bearing branches can lead to a significant decrease in yield. At the same time, intensive growth of the tops begins and there is a need for significant pruning to normalize, form and regulate the power of their development. Therefore, in old gardens the crown is reduced in two stages.

First, a moderate reduction of 1-2 m is carried out. At the same time, the conductor is removed and the center of the crown is opened. Skeletal branches are cut to external lateral branches. Increasing the access of light to the center of the crown and shortening the branches stimulate the awakening of dormant buds on the bare parts of the skeletal branches. As a result, semi-skeletal and small fruit-bearing branches are formed on them, and after 2-3 years the fruiting zone shifts deeper into the crown. After this, the height is reduced again to 3.5-4.5 m.

Formation of a sparsely layered crown in fruit trees

Varieties of apple trees grafted on semi-dwarf and sapling rootstocks and pear trees on quince A grow stronger than apple trees on paradise and pear trees on quince C. Therefore, their crowns thicken and require more thinning. The later entry into the fruiting season of trees on semi-dwarf and medium-sized rootstocks makes it possible to extend the period of formation in time. For fruit trees of this type, a sparsely layered crown should be recommended. It was developed at VNIIS named after. I.V. Michurina. Its essence boils down to the fact that three skeletal branches formed from adjacent buds are formed on the tree in the lower tier, and then a new tier of two or three branches is laid in the garden after 40-50 cm. It is better if the branches of the second tier are placed sparsely (through 1-2 buds). The distance between tiers in a continental climate can be reduced to 20-30 cm, and in the south increased to 60-70 cm. Then 1-2 more skeletal branches are laid sparsely at intervals of 15-25 cm. As soon as 5-6 skeletal branches are formed , the conductor is strongly depressed, or transferred to the side branch.

If orchard laid with annual seedlings, then in the year of planting they are pruned in the same way as when laying a tiered crown. Formation begins in the second year after planting, when good growth appears. Then they carry out similar works, which are performed with planted two-year-olds.

When releasing seedlings from the nursery, you should not limit the number of lateral branches, let there be 4-6 or even more. This will make it possible to select the three most promising branches in the garden. They will subsequently ensure the creation of a strong tree skeleton. The rest should not be deleted, as is sometimes recommended. It is better to shorten them by 4-6 buds (12-15 cm). If one of the three branches breaks, you can always select a replacement from trimmed branches. A powerful growth located next to the conductor (competitor) should also not be cut out in the first years, so as not to weaken the conductor. It is severely suppressed from year to year and only removed after 2-3 years.

The branches intended for the crown skeleton are cut weaker, by about ¼-1/3 of their length, and in order to ensure their proportional growth, they proceed in the same way as when forminglayered crown: strong ones cut more, weak ones cut very little or not at all. Take care of regulating the strength and direction of their growth.

In the year of planting, the growth is weak, so the laying of subsequent branches can only begin in the spring of the second year. For this purpose, the conductor is shortened at a height of 50-60 cm. If the branches of the first tier turn out to be very weak or the conductor has not reached the required height, the laying of subsequent branches is postponed for a year. In the south, where growth is most intense, branches are laid at 60-70 cm intervals and the conductor is cut at a height of 70-80 cm from the first tier. In harsh areas, the distance between the tiers is reduced to 20-30 cm and the conductor is cut by 30-40 cm. In the upper part of the conductor, after pruning, several shoots appear, of which 2-3 are selected that are well located in space, and the rest are pinched. In subsequent years (3-4th) the conductor is shortened so that another 1-2 branches can be laid at intervals of 20-25 cm. When 5-6 skeletal branches have been laid, the conductor is transferred to a side branch.

Branches of the second order begin to form on well-formed branches of the first order, usually in the third year after planting. To do this, they pour 50-60 cm from the trunk and cut them off, which makes it possible to obtain branches at a distance of approximately 40-50 cm from the central conductor (10-12 cm area where lateral branches are formed). Depending on the branching ability of the variety, 2-4 strong and several shortened shoots may form below the cut point. Of these, one is selected for the skeletal branch of the second order, and the rest are suppressed in the summer by pinching, pruning in the spring of next year, or bending back. A year later, using the same principle, a second skeletal branch is laid at a distance of 30-40 cm from the first. In one year it is impossible to lay two branches of the second order on one skeletal branch; for this, with good growth, it will take 2 years. In the process of forming a sparsely layered crown of fruit trees, pruning should also be reduced to the minimum necessary to create skeletal branches.

Branches of the second order must be formed due to increments located on the sidesskeletal bitch. If for this purpose a branch is taken from the underside of the main branch, it can subsequently easily break off under the weight of the harvest, since with the load the point of application of force will be at the place where the branches of the first and second orders grow together. If the branch is located on the side, then under the weight of the crop it will bend (spring) and will not break off.

To form second-order branches, it is impossible to select growths located on the inside of the skeletal branch, as this will lead to strong and unnecessary thickening of the crown. Second order branches in the tree crown should not intertwine. It is advisable to choose them so that the first of them are all located on the right or left side, and the second are also directed in one direction, the opposite.

In order not to create an excessively thickened crown, it is enough to lay two skeletal branches on the branches of the first order. The rest are converted by pruning into semi-skeletal (100-120 cm long) and shortened branches for fruiting.

The formation of a sparsely layered crown of fruit trees usually takes 5-6 years, and with poor care and poor growth, 7 years. Thus, by the beginning of fruiting, the main operations on the formation of fruit trees are completed.
