Fruit tree plastic pruning should pay attention to å•¥

Plastic pruning of fruit trees is a technical work that requires no damage to the development of fruit trees. Pay attention to the following points when pruning:

Develop a pruning plan. When fruit tree pruning is carried out, it is necessary to understand the condition of the fruit trees. It is necessary to carefully understand the fruit tree varieties, tree age, tree shape, growth status, and results, and observe the length, density, and number of flower buds. Master the fruit tree pruning response in recent years to avoid other problems in fruit trees during pruning, and then develop a pruning plan based on the principles and requirements of fruit tree shaping.

Note the order of the trimming. The pruning of the fruit trees must be in a reasonable order, starting from the upper part of the canopy, then the lower part of the canopy; first trimming the branches and leaves, then trimming the other branches; first trimming from the inside of the canopy, then trimming the outside of the canopy; Finally, the branches are combed, and the branches are combed and the twigs are combed.

Minimize damage to shoots. Branch buds are the new life of fruit trees. When pruning, be sure to wear tight-fitting clothes and soft-soled shoes. Try to use a ladder to trim and reduce the number of trees, thus reducing the damage to the shoots.

It is necessary to saw the big branches to get the law, but also to help the wound heal. Saw the big branch first from the bottom of the fruit tree, saw some shallow kerf from the bottom up, and then saw the big branch from top to bottom, so as to ensure that no stubs are left, and the branches are prevented from cracking to other Branches. In addition, it is necessary to ensure that the area of â€‹â€‹the kerf is small, the wound should be level with the mother branch, and the lower part should be raised to facilitate healing.

Pay attention to the protection of the pruning shears when trimming the thick branches. When making rough branches, you can hold the scissors in one hand and push the branches to the scissors at the other hand. The two hands cooperate with each other and the thick branches are cut off. Remember not to shake the scissors left or right while cutting the branches to avoid deformation of the knife edge.

When trimming, it is necessary to use various trimming methods. When pruning fruit trees, different pruning methods should be adopted according to the specific conditions: for example, in order to promote the extension of the backbone branches or to promote the branching, the short-cut method is often adopted; in order to promote the formation of flower buds, the plucking, topping and twisting are often used. Such methods; in order to update the complex group, the retracting method is adopted; in order to improve the ventilation and light transmission conditions, the method of removing the dense branches and the long branches can be adopted.

In short, for the plastic pruning of fruit trees, we must follow the principles, master the methods, and do the problems that should be paid attention to in the above pruning, so as to avoid blind pruning affecting the growth of fruit trees. Use the correct pruning method to promote the growth of fruit trees and increase yield and economic benefits.
