Plastic surgery is mostly aimed at young trees, including tree-like changes in the life of fruit trees. It regulates the crown of trees as a whole, and its main task is to cultivate and straighten out the skeleton structure of trees. Pruning is often used in adult fruit trees, including the shaping technology of young trees. Most of them are based on shaping to further solve the problem of local disharmony. The main task is to cultivate and renew fruit branches and adjust the relationship between growth and fruiting. It can be seen that shaping and pruning are not isolated from each other in technical operation, but closely related.
In a word, shaping is to make the tree into a tree with a certain shape, reasonable branch distribution, suitable branch placement direction, large bearing area and firm skeleton through pruning technology without violating the natural growth law of fruit trees. On the basis of shaping, the balance between the growth and fruiting of fruit trees is adjusted by pruning, and the light and heat resources, land and space are fully utilized, so that the branches are arranged reasonably and the ratio of long, medium and short branches is appropriate, which is conducive to early fruiting, early high yield, high quality and stable yield year after year, and the maximum economic benefits are obtained.
