The shaping and pruning of fruit trees broadly includes two aspects: shaping and pruning. Shaping is to cultivate a reasonable tree structure with a large effective photosynthetic area that can bear high yield, is convenient for management or is suitable for viewing in a certain spatial range according to the different requirements of different fruit trees' growth and fruiting habits, different site conditions, cultivation systems, management techniques and cultivation purposes. Pruning is a kind of artificial technology to prune, drain, remove the heart and retract the branches of different fruit trees according to their biological characteristics or the needs of beautification and appreciation. Or chemical agents, so as to promote or control the growth, branching or changing the growth angle of new shoots of fruit trees, and create a tree shape which conforms to the growth and fruiting habits of fruit trees or has ornamental value, thereby improving lighting conditions, adjusting nutrient distribution, reforming branch composition and adjusting or controlling the growth and fruiting of fruit trees. Plastic surgery is done by pruning; Pruning is carried out on the basis of a certain tree. Therefore, pruning is an inseparable two aspects, and it is also an essential technical measure for fruit trees to obtain high quality, high yield, high efficiency and low consumption under good cultivation and management conditions.

Fruit tree pruning is an indispensable and important technical measure in fruit tree cultivation management, and it is also a complicated and meticulous work, but it is not the only technology to increase production. It is closely related to growth and fruiting habits, tree age, growth intensity, different site conditions, integrated management of soil, fertilizer and water, and integrated pest control. Moreover, only on the basis of strengthening the comprehensive management of soil, fertilizer and water, and on the premise of normal growth of trees, the ideal economic effect can be achieved by comprehensively applying the plastic pruning technology.

Shaping mainly refers to deciding what shape to shape a fruit tree according to its growth and fruiting habits and different cultivation purposes. So shaping is the first step of pruning. In order to obtain an ideal tree shape, pruning is needed to make the trunk height appropriate, the direction, distance and length of the main branch and the lateral branch appropriate, and the growth of each other is balanced, neither too strong nor too weak. After molding, in order to obtain stable high quality and high yield, pruning should be carried out every year according to the needs, such as thinning branches, cutting short or opening corners, and coring. Therefore, the economic fruit age can be prolonged and the highest economic benefit can be obtained until the tree becomes old and loses its economic value.

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, pruning is often used to adjust the balance between the growth and fruiting of fruit trees, make full use of light and heat resources, land and space, make the allocation of branches reasonable, and make the proportion of long, medium and short branches appropriate, which is conducive to early fruiting and early high yield, and obtain excellent, high and stable yield year after year, and obtain the greatest economic benefits.
