1, refinement
Generally speaking, thinning is to properly remove branches that grow too densely and have improper position angles from the base, so as to reduce the obstruction of leafy trees to ventilation and light transmission and reduce the consumption of nutrients by ineffective branches. Through thinning, the ventilation and light transmission environment of plum trees can be greatly improved, which is very beneficial to the expansion and development of fruits and the improvement of sweetness and yield in the later stage. ?
2. Shortcuts?
The pruning method of short cutting is to cut off a part of branches in the growth period of fruit trees every year, and carry out different degrees of short cutting, medium cutting and heavy cutting according to the growth situation of fruit trees and the purpose of selecting, retaining and cultivating branches. When pruning short branches, it should be noted that short branches are generally not conducive to the formation of flower buds, but short branches and weak branches can adjust the total number of branch buds and nutritional status, but can promote the differentiation of flower buds, and short branches can improve the fruit setting rate of fruit trees. ?
3. Slow release
The main function of slow release is to slow down the growth of fruit trees and promote the differentiation of flower buds. General 1 year-old branches are not pruned, and let them grow naturally. When the upright branches on fruit trees are slowly released, the branches should be twisted or leveled from the base, and the branches after slow release should be retracted or cut short after they grow into flowers and fruits, so as to effectively achieve the effect of slow release. ?
4. Shrinkage and shearing
The main function of pruning is to promote the replacement of new and old branches, ensure the centralized supply of nutrients, and revitalize old and weak trees. Generally used for shrinking and pruning weak trees or perennial weak branches in aging period.
