This question is very professional. 1. There are two kinds of fruit tree pruning: winter pruning and summer pruning. 2. Pruning is mainly to cut off long branches, drooping branches, back branches, too dense branches, branches with pests and diseases and weak branches. Pruning can control the yield of fruit trees and improve fruit quality. 3. Pruning is for fruit tree shaping, pear tree is in the shape of three main branches, peach is in the shape of three main branches, and pomegranate is in the shape of natural round head. Summer pruning is from June to August. As long as you feel dense, you can cut some branchlets from the branches, which can be modeled by light, but don't cut off the fruiting branches, otherwise you won't be able to eat the fruit. 5. Short pruning is the main pruning method in winter, that is, cutting off some branches from the top, accounting for 1.

Or half of 1

The purpose is to promote the growth of fruit trees, reduce fruit, and cut off some fruit branches, because the fruit of fruit trees is causal, and more fruits will become smaller.

Because this question is very professional, I graduated from the fruit tree major. I have worked for six years and have some experience. However, I can't say a few words clearly about professional things. I suggest you go to the library to read the information about fruit trees.
