What is the effect of apple tree pruning?
(1) plastic pruning is beneficial to flower bud formation.

The formation of flower buds can be promoted by cutting methods such as long planting, keeping branches (cutting high-yield branches), cutting top branches to break top buds, thinning branches, cutting in summer and thinning fruit branches.

(2) Plastic trimming is beneficial to the utilization of light energy.

Pruning can make fruit trees and orchards have good individual structure and group structure, improve lighting conditions and be beneficial to nutrient accumulation.

(3) Pruning is beneficial to the utilization of water and nutrition by trees.

On the one hand, pruning plays a great role in the production, operation and distribution of water and nutrients in trees; On the other hand, pruning can keep a proper amount of vegetative branches in the tree, and the proportion of long, medium and short branches is appropriate, which can play a role in regulating tree vigor, nutrition and yield; Thirdly, the accumulation of nutrients can be increased by pruning (young trees are lightly pruned and leave more branches, which leads to the improvement of light conditions of trees), and measures such as limiting excessive growth, creating reasonable branch composition, adjusting flower quantity, reasonably thinning branches, improving light, and thinning slender weak branches (parasitic branches) in the inner cavity can be taken to reduce nutrient consumption.

(4) Cultivation and management conditions such as shaping and pruning.

Environmental conditions and management measures directly affect the growth and fruiting of fruit trees, thus affecting the pruning reaction. If the management level of soil, fertilizer and water is high, the orchard is low-lying and the fruit trees grow vigorously, the pruning reaction will be strong; On the contrary, fruit trees grow slowly and bear fruit easily, so the pruning reaction is weak. Therefore, the plastic pruning technology has great regional and flexibility.
