The suitable tree shape of persimmon mainly includes sparse shape and natural round head shape. The focus of pruning young trees is to straighten the tree shape, select and retain the main lateral branches, properly cut off the branches extending from the central trunk, and adjust and match the growth potential and master-slave relationship of all kinds of branches. When the new shoot grows to about 40cm, pick the core, promote the branch to expand the crown, pay attention to the direction and angle of the main branch, keep the balance between branches and increase the number of branches. The sparse and weak branches should be retracted and updated in time to cultivate a compact fruiting branch group. In the full fruit period, the key point of the tree is to cultivate the inner branches, prevent the fruit from moving out, and pay attention to ventilation and light transmission. It is necessary to shrink the combination, renew the cultured branchlets, maintain the tree vigor and prolong the fruiting period. The drooping backbone branches should be shrunk, and the upward inclined branches should be shrunk. The branch group can be pruned by double branch regeneration and single branch regeneration. Pruning in the winter of the first year, keeping 2/3 of the fruiting mother branch in the upper part of the branch group, selecting13 of the fruiting mother branch in the lower part of the branch group, cutting off 2-3 buds at the base, and cultivating the fruiting mother branch in the second year; When cutting in the winter of the next year, continue to cut off 1/3 bearing mother branches, and cut off the branches bearing fruit in the second year. Single-branch regeneration refers to using the same mother branch to cut short the strong-bearing mother branch, so that it can produce fruiting branches under the cut, and then cut them off after fruiting, and the lower unfruitful branches are the fruiting mother branches of the next year. For long branches, those with space can be used to cultivate fruiting branches to fill the space; What has no space can be thinned. At the same time, dense branches, cross branches, overlapping branches, diseased branches, etc. should be thinned out during the full fruit period.
