What are the principles of cherry pruning, cherry tree pruning technology points

In principle, cherry pruning is mainly carried out in the growing season, but due to the constraints of the actual production situation, sometimes the pruning work in the growing season is not in place, so it needs to be adjusted by pruning before bud break in spring. Before germination, pruning should try not to move large branches, reduce wounds to prevent glue flow, and remove over-dense branches and competing branches with less stubbing. Pruning is generally required to be completed by March 10.

The pruning principles for fruit trees of different periods are:

1. Thin the upright main branches that are too vigorous on the middle stem and the long branches that are too vigorous on the main branch, and mainly pull the branch opening angle and cut the buds on the retained main branch and the lateral branches on the main branch. The opening angle of the main branch is 60-70 degrees, and the opening angle of the side branches is 70-80 degrees.

2. In the early fruiting stage of the tree is 4-7 years old, it is necessary to adjust the structure of the tree and pay attention to the cultivation of the fruiting branch group on the main branch. The first is to gradually remove the main branches that are too low and too dense, so that the main branches do not affect each other; The second is to properly retract the absence of branches to promote branching. The third is to retract or shorten the lateral branches that are too weak, and ease the growth of the excessively strong opening angle to promote flowering.

3. Adjust the tree structure to improve the scenery conditions in the canopy during the full fruiting period, resolutely thin out the excess upright branches, overly dense branches, overlapping branches, and cross branches that sprout in the canopy, and open the layer spacing to avoid disturbing the tree shape and consuming nutrients. If the tree is too tall, it will be happy to use weak branches to take the lead in controlling the height of the canopy.

How to prune a cherry tree properly? to make the cherry tree grow better!

Prune the side branches, after the cherry tree germinates, it is necessary to cut off its waste buds, diseased branches and leaves, so that the branches and buds are more full; Retraction pruning, when the fruit of the cherry grows too fast, it is necessary to retract pruning, so that new shoots can grow again in the retracted position; Pruning time, pruning time is generally in May and June every year, and pruning can also be carried out in autumn; After cutting, it is necessary to use carbendazim to disinfect the wound after pruning.

1. Prune the side branches.

After the cherry tree begins to germinate, it is necessary to cut off the new branch buds on the main branch and side branches in time, and cut off the waste buds, diseased branches and branch buds that cannot bear fruit.

2. Retract pruning.

When the fruit of the cherry grows too fast, the growth rate of the new shoots will be slow, and it is necessary to retract the fruiting branches and leaves to make new shoots grow back in the retracted positions. However, it is necessary to keep the strong branch buds as replacement branches, and apply fungicides in time after pruning.

3. Pruning time.

Cherry branches and leaves are generally pruned in May and June each year, but they can also be pruned in early autumn and December in winter. Spring pruning needs to be advanced due to the slower growth rate of cherries, and if the cherries are more robust, the pruning time can be postponed.

4. Post-cutting maintenance.

After pruning the cherry tree, it is necessary to sterilize and disinfect the wound, plant ash, chlorothalonil, carbendazim, etc., in order not to make the wound infected and affect the growth rate of the cherry tree, it is necessary to water it once after pruning to make it regain its vitality as soon as possible.

When pruning, be sure to prune some dead branches and rotten leaves, and then you can spray some nutrient solution, and at the same time, you should prune to make a beautiful shape, and prune some dry branches, so that the cherry tree can grow and develop better, so as not to affect the yield.

When pruning the cherry tree, be sure to prune some excess small branches, for the large branches can not be pruned at will, if there are some diseased branches and diseased fruits during the management period, you can choose to prune the diseased branches or diseased fruits reasonably.

Try to choose to use scissors that are specially used to cut trees directly, and try to choose to use an oblique cut before cutting, so that it will be better to deal with it later, and it will be more convenient.

The pruning of cherry trees needs to pay special attention to the climate and time, generally small cherry trees are suitable for summer pruning, and cherry trees in the full fruit period are suitable for winter pruning, and the specific pruning method still needs to be reasonably matched.

1. Pruning of young trees: cut off the upright main branches that grow too vigorously on the trunk of the cherry tree, and cut the buds of the cherry tree in March every year to promote flowering. 2. Pruning at the early fruit stage

The lateral branches of the main trunk near the base are cut off and the unbranched main branches are retracted. 3. Pruning during the full fruit period: cut off the large branches that affect the light, and thinly prune dense branches, long branches, and overlapping branches.

1. Pruning young trees

When the cherry tree is in the young tree stage, the upright main branch that grows too vigorously on the main trunk should be cut off, and then the long branches on the remaining main branch should be cut off to reduce nutrient consumption.

2. Pruning at the early fruit stage

Cherry trees grow for 4 to 7 years after the first fruiting stage, at this time the main trunk close to the base of the side branches to prune, and then thinning the growth of too dense main branches, save nutrients, and to retract the unbranched main branch extension branches, to promote branch germination, but also to the too weak side branches for shortening.

3. Pruning during the full fruit period

In the peak fruiting period, the cherry tree should be thinned and shortened, first of all, the large branches that affect the light and the useless auxiliary branches should be cut off from the base, and then the cross branches, overlapping branches, dense branches, and upright branches in the crown should be thinned to improve air permeability.

1. Cherry tree stub pruning method (1) The light stub method is to cut off the 1 5 1 4 of the cherry branches; Light stubbing has the effect of weakening the dominance of the tip of the branch, which is conducive to improving the germination rate, increasing the number of short branches, and forming more bouquet-like fruiting branches. Therefore, light stubbing of horizontal branches and oblique branches on young trees can increase the number of short branches, which is conducive to early fruiting. (2) cut off the 1 3 1 2 of the cherry branches by the short truncation method; In the process of cherry tree shaping and pruning, the slag is usually cut off for the backbone branches and the developing branches with growth space on the periphery, which can generally promote 3 5 medium and long branches, which is conducive to expanding the canopy.

3) the heavy stubbing method to cut off the 2 3 of the branches of the cherry tree; This method is mostly used to balance the tree potential of young trees, such as the implementation of heavy stubbing of the annual strong branches of the strong branches, which can reduce the growth potential of the branches. It can also be used to cultivate fruiting branch groups, such as stubbing the upper branches on the back of the backbone branches, depressing the branch parts, and then slowly putting the branches in the second year to cultivate the fruiting branch group. (4) The extremely heavy truncation method only leaves 4 or 5 buds at the base of the cherry tree.

This method is mostly used to control competing branches and over-flourishing branches. When there are axillary flower buds at the base of the branch to be thinned, you can first stub it very heavily to retain the flower buds at the base and wait for fruit.

There are different ways to prune cherry trees, and you should pay attention to the technique, and you should also prune some withered branches and leaves, and you should choose a very good time to prune.

1. First of all, you need to prune off the withered branches and leaves, these withered branches and leaves will affect the growth of cherry trees, and some older leaves are also pruned off, which needs to be paid attention to. 2. There are also some borer branches should also be pruned off, so as to avoid borers continuing to erode the branches, this is something that needs special attention, after pruning, the cherry tree can bear more fruit in the next year. 3. When pruning, the angle is very important, generally choose 45 ° for pruning, if you don't want the cherry tree to grow too tall, then you need to carry out topping treatment, so as to avoid it growing too tall.

Prune off the excess branches, and pay attention to protect the roots of the cherries, pay attention to protection after pruning, but also pay attention to skills, do not prune indiscriminately, and so on.

The first is early topping, 10 days after flowering, leaving about 10 cm of new shoots, topping. The control of the canopy and the growth of the fruiting branch group are favorable. The second is the topping during the growth period, which is usually carried out from the end of May to the middle of July, and the topping of about 30 cm of new shoots is retained, which can increase the branches of the cherry tree.

When the secondary shoots are still vigorous after topping, a second topping can be carried out to promote the formation of short branches and early fruiting. From late May to early June, when the new shoots reach semi-lignification and have not yet lignified, place the upright branches and competing branches at a distance of 3 5 cm from the branch base, and gently twist them 180 degrees. After twisting the shoots, the growth slows down, and the accumulation of nutrients in the upper part increases, so that the top and side buds gain more nutrients, which is conducive to differentiation into flower buds.

No buds can grow on the branches, but flower buds can grow the next year. Not sooner, not later. Early maturity is due to the fact that the new shoots are not semi-lignified, the tissues are tender and weak, and the leaves are small and few, which is not conducive to the formation of flower buds.

When it is late, the branches have been lignified, hard and brittle, and it is easy to break when the tips are twisted, resulting in dead branches. Pulling branches is mainly used to adjust the angle of backbone branches and auxiliary branches, ease the tree momentum, and improve the ventilation and light transmission conditions of the tree. Because cherry is a photosynthetic tree species, under management and light conditions, its hand matrix is strong, the branches are long-lived, the buds are full, the fruit setting rate is high, the maturity is early, and the coloring is good.

After the fruit is picked, it should be done in early spring or after the harvest in June. <>

After the harvest of thin-branched cherries, in order to adjust the tree structure, to solve the problem of ventilation and light transmission in the crown, in the case of canopy closure and poor ventilation conditions, we should seize the favorable opportunity after fruit picking to adjust the structure of the tree. For the erect branches that affect the ventilation and light conditions in the crown, the strong branches that have no retention value should be thinned from the base. For large branches that only affect local lighting conditions but have a certain effect, they can be reduced in the places where there are branches.

In this way, it can make the cherry tree grow more vigorously, or it can also be used to increase the yield, and then it can also prevent the occurrence of pests and diseases, and it will not cause nutrients to be absorbed by dead branches and leaves in the future.

It can promote the yield of cherry sail peaches, reduce pests and diseases, improve the fruit before bending acres, shorten the cycle, and ensure the absorption of nutrients and reduce the loss of nutrients in the soil.

This kind of selling can make cherries grow better, can make cherries grow bigger and redder, will not be absorbed by excess branches, and can also make cherries sweeter, so that the cherries are also very sweet, the taste is particularly good, and the taste is also very good.

It can improve the quality of cherries, greatly increase the yield of cherries, prevent pests and diseases, can bear fruit in advance, and can promote the growth of plants.
