How can cherry trees be pruned to bear fruit?
Pruning cherry trees in this way can produce fruit:

1, cherry tree pruning method

(1) light short truncation method

That is,1/5 ~1/4 of cherry branches are cut off; Light cutting and short cutting can weaken the advantage of branch top, which is beneficial to improve germination rate, increase the amount of short branches and form more fruit branches. Therefore, light pruning and short pruning of horizontal branches and oblique branches on young trees can increase the amount of short branches and facilitate early fruiting.

(2) Shortcut method

Prune cherry branches1/3 ~1/2; In the process of pruning cherry trees, the main branches and developing branches with growth space around them are usually cut into short and medium-long branches, which can generally promote 3 ~ 5 medium-long branches and help expand the crown.

(3) Heavy and short cutting method

Cut off two-thirds of the branches of the cherry tree; This method is mostly used to balance the tree potential of young trees. For example, the annual strong branches and strong branches can be cut off, which can reduce the growth vitality of strong branches. It can also be used to cultivate fruiting branches, such as cutting off the branches on the back of main branches, lowering the position of hair branches, and slowly releasing branches in the next year to cultivate fruiting branches.

(4) Extremely heavy and short cutting method

There are only 4 ~ 5 buds left at the base of the cherry tree. This method is mostly used to control competing branches and excessive branches. When there are axillary flower buds at the base of the branches to be thinned, extremely heavy short cutting can be carried out first, and the flower buds at the base can be kept, and then thinning can be carried out after the results are obtained.

2. Pruning method for thinning cherry trees

Pruning is mainly to remove too dense branches, cross branches and overlapping branches of cherry, which can reduce nutrient consumption and improve lighting conditions. However, the pruning and thinning of cherry cultivated in protected field should not be too much, and the tree shape should be adjusted mainly after the fruit is harvested. Moreover, in order to protect the wound, lead oil can be applied to the wound, so as not to cause the wound to flow or dry.

3. Pruning method of cherry tree retraction

(1) retraction has the functions of reducing fruiting parts, saving nutrition and enhancing growth potential, and is often used for regeneration and rejuvenation of fruit-bearing branches. If you cut the drooping branches to the upper branches, cut the weak branches to the strong branches.

(2) For cherry trees in full fruit stage, the growth potential of new shoots weakened, some branches drooped, and baldness appeared in the middle and lower part of the crown. In order to improve the light, reduce the number of branchlets on the big branches, so that nutrients and water can be supplied to the remaining branches in a centralized way, and as a result, the branches are renewed and rejuvenated through retraction. After the big branches are retracted, several sprouting strips can be pulled out from the retracted position. We should choose a robust and suitable branch as the regeneration branch and adjust the angle in time. Excess sprouting strips should be removed to promote the growth of regenerated branches.

4, cherry tree slow-release pruning method

(1) Not pruning 1 annual branches is called slow release. Generally speaking, the growth potential of slow-release branches decreased year by year, the middle and long branches decreased, and the short branches and bouquetlike fruit branches increased, which was beneficial to fruit bearing.

(2) However, it is not advisable to slow down the vigorous branches, especially the upright vigorous branches. Even if you slow down, you should be submerged before you slow down. Young sweet cherry trees and early fruiting trees can slow down some flat branches and oblique branches with moderate growth potential, and promote more bouquetlike fruit branches to bear fruit early.
