The best autumn cut period for walnut trees is before the walnuts are harvested, and the leaves are slightly yellow to the leaves (between September and November). The specific pruning method is as follows: The pruning and pruning of the first fruit trees is mainly to continue to cultivate the backbone branches at all levels to make rational use of the auxiliary branches. In addition, according to the plastic surgery requirements, the large branches and long branches are removed, so that the backbones of all levels are distributed reasonably, and the subordinates are distinct; the canopy of the canopy should be properly retained, and the new branches should be continuously cultivated as the crown expands, paying attention to keeping the branches dense and moderate. And growth to increase the area of ​​results. In terms of tree balance, the method of strengthening the weak and proper short-cutting and extending the branches is adopted for the strong backbone branches; for the weak-rooted backbone branches, the multi-cut vegetative shoots are used, and the long cuts are used to extend the branches. Pruning the tree during the fruiting period. For the tree with strong growth, the pruning focus is to remove the large branches and the long branches of the inner gangsters, and clean the branches of the canopy; the pruning of the moderate tree is mainly based on the removal of the densely-branched branches. Attention should be paid to the update and rejuvenation of the branch group, and the method of weakening and strengthening the branch group, increasing the new branch cutting, removing the sagging weak branch, retracting the long branch group, and raising the drooping branch group. In addition, the delicate branches, dry branches, overlapping branches, drooping branches, and diseased branches of the inside and outside of the canopy should be cut off from the base as much as possible, and the robust branches of the inner sputum should be properly preserved to facilitate the internal sputum results. The overly dense branches should be thinned year by year, and the wounds should be flattened when cut to promote good healing. The main task of pruning aging trees (including weak trees) is to rejuvenate. Focus on the retraction of the backbone branches and the drooping branches, and choose a better leading branch in the retraction to promote wound healing and bud sprouting, making it a strong new extension branch and enhance the tree potential. For the old trees that are too weak, the backbone branches can be renewed, and the crowns can be re-formed by using the buds to sprout strong branches. It is necessary to select and cultivate the updated long branches in time, and cultivate the long-distance branches with good orientation into new backbone branches and extension branches. For the general new branches, the branching group can be cultivated by pulling the branches slowly, and the amount of branches and yield can be increased as soon as possible. To restore the crown crown as early as possible. Disclaimer: Some articles on this website are transferred from the Internet.
