Pruning and pruning of fruit trees, in a broad sense, includes two aspects: shaping and pruning. Shaping is based on the growth and fruiting habits of different fruit tree species, different site conditions, cultivation systems, management techniques, and different cultivation purpose requirements, etc., to cultivate a larger effective photosynthetic area within a certain spatial range, which can afford higher Yield refers to a reasonable tree structure that is easy to manage or suitable for viewing; pruning is based on the biological characteristics of different fruit tree species or the needs of beautification and viewing, through artificial techniques such as short cutting, thinning, topping, retraction, etc. or chemical agents , treat the branches of fruit trees to promote or control the growth and branching of new shoots or change the growth angle, so as to form a tree shape that conforms to the growth and fruiting habits of fruit trees or has ornamental value, so as to improve light conditions, regulate nutrient distribution, and transform Branch composition, techniques for regulating or controlling the growth and fruiting of fruit trees. Shaping is done through pruning; pruning is done on the basis of a certain tree shape. Therefore, shaping and pruning are two inseparable aspects, and they are also essential technical measures for fruit trees to obtain high quality, high yield, high efficiency and low consumption under good cultivation and management conditions.

The shaping and pruning of fruit trees is an indispensable and important technical measure in fruit tree cultivation and management. It is also a complex and meticulous work, but it is not the only yield-increasing technology. It is closely related to the growth and fruiting habits of different tree species and varieties, tree age and growth strength, as well as different site conditions, comprehensive management of soil, fertilizer, and water, and comprehensive prevention and control of pests and diseases. Moreover, it can only be strengthened when comprehensive management of soil, fertilizer, and water is strengthened. Basically, under the premise that the tree body grows normally, only by comprehensively applying shaping and pruning techniques can we achieve ideal economic results.

Plastic shaping mainly refers to deciding what shape to shape the fruit tree into according to its growth and fruiting habits and different cultivation purposes during its young age. Therefore, shaping is the first step in pruning. In order to obtain the ideal tree shape, it is necessary to prune so that the height of the trunk is appropriate, the orientation, distance and length of the main and side branches are appropriate, and the growth of each other is balanced, neither too strong nor too weak. After forming, in order to obtain stable high-quality and high yields , and pruning should be carried out every year as needed, such as thinning branches, shortening or cutting corners, topping, etc., in order to extend the economic fruit life and obtain the highest economic benefits, until the tree body ages and loses economic value, and then the whole garden is renewed. .

In short, plastic surgery is to use pruning technology to shape the tree into a certain shape, reasonable branch distribution, appropriate branch orientation, large fruiting area, and skeleton without violating the natural growth laws of fruit trees. Firm tree shape; on the basis of shaping, regular pruning is used to adjust the balanced relationship between fruit tree growth and fruiting, making full use of light and heat resources, land and space, so that the branch group is reasonably equipped and the proportion of long, medium and short branches is appropriate. In order to facilitate early fruiting and early high yield, and achieve excellent, high and stable yields year after year, the maximum economic benefits can be obtained.
