Pruning persimmon trees in winter is 1, and pruning young trees. Build a good skeleton to cultivate a tree shape, pay attention to the balance of branch strength and the subordinate relationship between main branches, pick the heart in time, and promote the growth and fruiting of mother branches. Fixed dry height 1.2m, and selected main branches according to tree structure. Less thinning, more cutting, more branches. It is necessary to combine winter and summer. When the flourishing branches grow to 20-30 cm, it is necessary to remove the heart, promote the growth of secondary branches, and cultivate the light branches as much as possible to prepare for early fruiting. 2. Pruning of trees in full fruit. The persimmon tree is about 10, that is, it enters the full fruit stage. With the increase of age, the dark buds in the inner chamber began to germinate, and new branches naturally regenerated. Attention should be paid to ventilation and light transmission. Cultivate inner-bore branchlets to prevent the fruiting parts from moving outward, combine thinning and shrinking, cultivate new branches, update them in time, keep the tree vigor and prolong the full fruit period. Pruning method: adjust the angle of backbone branches to balance the tree potential; Too many big branches should be thinned in different years to promote the growth and fruiting of inner cavity branchlets. Retract the original head of the big branch year by year, and at the same time support the later updated branches to grow obliquely upwards, gradually replacing the original head, thus raising the angle of the main branch and restoring the growth potential of the main branch. The cultivation of endoluminal branches needs the combination of dewatering and shrinkage. When pruning, it should be retracted to promote the regeneration of the back branches, and the weak ones should be removed to keep the strong ones, and the head should be cut off at the right time to promote its branching and cultivate the branches. The inner branches should be contracted and released, and attention should be paid to culture. Too high and too long old branches should be retracted in time to promote the regeneration of lower branches. For short and thin branches, they should be released first and then shrunk to increase the number of branches and promote their youthfulness. Years of practice have proved that the fruiting branch or fruiting mother branch should be cut short every year as a reserve branch, so that it can bear fruit every other year, which can overcome the big and small years. Short branches should be stout, and there are lateral buds at the lower part to send out new branches.
