After potted 1 ~ 2 years, attention should be paid to pulling branches and opening corners to make the trees ventilated and transparent, so as to facilitate the formation of flower buds and obtain early fruit and high yield. When pruning, the branches of 1 a are chopped again to stimulate axillary bud germination and form a small crown tree with compact fruit. The first-bearing tree bears fruit through long, medium and short branches and terminal buds. After entering the fruiting stage, according to the strength of growth, 2 ~ 3 full buds can be left at the base for re-cutting. Long branches can be reduced to 2-year-old branches, so that small and medium-sized fruit branches in the crown are densely distributed. At the same time, the method of winding and pulling branches is adopted to inhibit the growth of trees and promote the development of new branches. The branches that were pulled up in the same year are cored, the trunk is strengthened, and then new branches are issued. By kinking, coring, cutting and girdling long and competitive branches, a large number of fruiting branches can be cultivated and flower buds can be promoted, so as to achieve the goal of early fruiting and multi-fruiting.
