Shaping refers to the process of shaping the crown into a certain structure and shape by pruning technology according to the needs of production or viewing. Such as three-dimensional pruning, plane pruning, dragon stem pruning, etc. In production, in order to make the skeleton structure of trees distribute reasonably, facilitate various cultivation management, make full use of sunlight, and achieve high quality and high yield, it is generally necessary to carry out plastic surgery. Therefore, the purpose of plastic surgery is to cultivate backbone branches that meet various requirements, starting from the young seedling stage. In the operation, it is required to continue every year until the crown is formed. As short as 5 ~ 7 years, as long as 8 ~ 10 years, or even longer.
Pruning refers to various surgical pruning and cutting measures taken on specific branches. Such as cutting short, thinning branches, slow release, retraction, bending, damage and other pruning methods. The purpose of pruning is sometimes to cultivate backbone branches and fruiting branches, sometimes to control the crown size, sometimes to adjust the relationship between tree growth and fruiting, and sometimes to protect trees and reduce natural disasters. In order to make young trees take shape quickly and big trees have high quality and high yield for a long time, the trees that have grown and changed should be pruned regularly and in time.
Shaping and pruning are two different concepts. 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. However, shaping and pruning are not isolated from each other in technical operation, but closely related. They are two sides of a unified, simultaneous and inseparable problem. Plastic surgery can only be achieved through pruning technology, and pruning technology can only play a better role if the tree structure is reasonable. Therefore, shaping is the premise and foundation, and pruning is the continuation and guarantee. The two should cooperate closely and complement each other.
