The pruning of fruit trees before or after flowering in spring is called spring shearing. The spring shearing can make up for the lack of winter shear. If used properly, it can regulate the relationship between growth and results, promote flower bud differentiation and the occurrence of mother trees, increase fruit setting rate, promote young fruit development, overcome the phenomenon of fruit tree size, and mitigate young age. The growth of the tree and promotion of multiple branches facilitates the control of the crown and the cultivation of the resulting branches.

First, cutting time
The complex shearing is performed after the temperature rises and stabilizes in spring and when the fruit tree sprouts to clearly distinguish leaf buds and flower buds, and is cut before the bud enlargement period.
Second, cutting sequence
Before pruning, the degree of pruning must be determined according to the conditions of the orchard, tree age, tree vigor, and frost damage degree. Generally, the mature tree is first cut and then the young tree is cut; the weak tree and early flowering varieties are cut first; The variety.
Third, cutting method
1. For fruit trees in full fruit period, adjust the ratio of growing branches to the result branches 3-1, and carefully trim the resulting mother branches to make them reasonable and reasonable. In the pruning method, sparse cutting is the main method, and the short section is supplemented, thus playing the role of strong flowers and fruits.
2. For older trees with more flower buds, we should master the principles of sparse retention and strength and renew the branches of old and dense branches, and appropriately short and medium-length fruit branches. Sparsely cut dense cross-trees and other thin branches in the upper and middle of the crown.
3. To spend as little as possible on the old tree to spend more flower buds, sparse dense nutrition.
4. In addition to the normal short cuts, the remaining branches of the saplings may be long or short to facilitate the growth of shoots. At the same time to eliminate dense growth branches and leggy branches, the main branch of the sapling pull branches shaped, laying the foundation for high yield.
5. For the frozen fruit trees, we should master the principle of "small injury, picking leaves, smashing and slicing, and severe injury and sawing." After the frozen shoots are still dry and the leaves dry, they should be removed as soon as possible; for the frozen shoots, the dead shoots should be cut off; if the freeze is severe, the whole canopy freezes, the trunk should be sawn and cultivated. 2-3 growing branches become the backbone branches.
Fourth, pay attention to matters
1. The complex shear must be combined with good fertilizer and water management in order to receive good results.
2. The mountain orchards pay attention to the work of drought prevention and drought relief.
3. Pay attention to the protection of lychee twigs. Generally, only the results of tinea sisola are short cut to promote its robustness.
4. Excessive pruning will severely impair the growth of the roots, causing rapid decline in tree vigor and must be prevented.
5. Pay attention to protect the wound and strengthen the prevention and control of pests and diseases.
