Pruning technology of fruit trees, pruning during the growth period is divided into three seasons: spring, summer and autumn. Spring pruning is performed after spring budding and before flowering. Re-pruning before flowering is a review and supplement of winter pruning tasks, mainly to further adjust growth potential and flower amount. For example, when the flower buds of apples are difficult to identify, you can consciously leave some more "flower buds" during winter pruning, and perform a second pruning before the flower buds bloom to bloom, thin out the excessive flower buds, and retract the lengthy branch groups, so as to have It is beneficial to control the amount of flowers, improve the fruit setting rate and the cultivation of fruiting branch groups.

Summer pruning, summer is the peak growth period of fruit trees, and it is also a good time to control the growth. Many fruit trees use summer pruning to control branch growth, reduce nutrient consumption, and facilitate tree growth, flower bud formation, and growth. Increasing the fruit setting rate can also improve the lighting conditions inside the canopy and improve fruit quality. Commonly used measures include propping branches to open corners, topping and thinning branches, and twisting branches. Girdling, girdling, etc. are indispensable technical measures for grape, peach and apple saplings.

Autumn pruning. Pruning over-prosperous trees before the leaves fall in autumn can control the tree vigor and control the growth of branches. At this time, large branches are thinned out and pruned back, which has less local irritation. It is often used for some tree species and varieties that are sensitive to pruning.
