Definition: That is to cut a part of the annual branch.
Role: Increase branching, enhance local growth potential and enhance vegetative growth.
Method: According to the degree of pruning is divided into light and short cut, short and medium cut, heavy short cut, extremely heavy short cut.
Light and short cut: Cut 1/4 to 1/3 of annual branches. The purpose is to reduce the branching force of annual branches with large branching angles, increase the number of short branches, and promote the transformation of shoots into fruiting branches.
In the short cut: In the middle of the annual branches full buds short cut, cut the original branch length of about 1/2 to 1/3. Since the quality of the clipped buds is good, 3 to 5 medium and long branches can be drawn after a short cut. For the central stem and the extension branches of the main lateral branches, the sapling stage uses multiple short cuts to enlarge the crown. In the weak branching varieties, more and more short cuts can be used to increase branches. Weak tree regeneration and rejuvenation can also be used to restore the tree potential.
Heavy short cuts: Short cuts in full shoots in middle and lower branches of annual branches.
Extremely short: cut short at the axillary bud at the base of the shoot. To use the back branches to cultivate small branches of fruit, the first year is very heavy and short, and then the vigorous and upright branches are removed, and the medium and short mean trees can be formed in small groups.
