There are mainly four forms: cutting, thinning, releasing and shrinking.
The cultivation and winter pruning of main branches must correct the subordinate relationship between main branches. The distribution of main branches must be non-overlapping and non-overlapping, and branches with large plant spacing should avoid each other through pruning in winter and do not affect each other. There should be an optical path between rows, and the distance between rows should be at least 0.5 meters, so as to achieve the purpose of ventilation and light transmission.
The cultivation and regeneration of branches should pay attention to the continuous regeneration and pruning of branches every winter, so that enough medium-long fruit branches can be produced in the branches. There are two ways: first, put it first and then shrink it; Second, cut before you put it. Generally speaking, the branches should be distributed on both sides of the main lateral branches, with the emphasis on crosswise. The middle branchlets should stay on the back of the main lateral branches. The height shall not exceed 0.4m, and larger branches shall be arranged in the middle and lower parts with larger space. The branches of the whole tree should match each other, and the branches should not cross or overlap. By using reasonable methods such as retraction, short cutting and long placing, the branches are kept in one place and dispersed.
Pruning fruiting branches Pruning fruiting branches should be carried out according to the growth potential of trees and the distribution of various fruiting branches. Results the long fruit branches in the branches should stay on one side of the branches and be inclined. Leave not too long fruit branches on the back or erect; Overgrowth of fruiting branches in the upper part of the crown is determined not to stay. First-fruiting trees and trees that are not easy to bear fruit because of excessive growth are mainly sparse and long-released, and the branches are lightly shrunk, so that fewer branches are cut and more fruit branches are left, which promotes the relaxation of trees and improves the fruit-bearing ability; Adult trees should adopt the method of long release and shearing shrinkage. Generally, long fruit branches should be cut off from the unfinished top, and the length of the top is1/4-L. The middle fruit branches are mainly long, and short fruit branches should never be cut off. Old or weak trees should be thinned less and cut more to control the fruit yield, strengthen the regeneration of branches and promote the recovery of tree potential.
