1, the trees are mainly happy trees with many main branches; 2. Pruning in the young tree period, when the young tree period of Kaite apricot grows vigorously, the branches are erect, and pruning in this period is mainly based on short branches to promote the branches to expand the crown. Pay attention to the opening angle of main branches, select and keep the main branches, keep as many auxiliary branches as possible, accumulate nutrients in advance and bear fruit early. When cutting in winter, cut the central trunk of the main branch short, generally 50 cm. In summer, the core of new buds is removed, which stimulates the germination of two branches and makes the crown form early. Twisting new branches and pulling branches to promote early fruiting of young trees;
3. Pruning at the first fruit stage. In the first fruit stage, Kaite apricot still maintained vigorous growth potential, and the growth of big branches and nutrition was greater than that of reproduction. At this stage, on the basis of maintaining the tree shape, we should constantly expand the crown and cultivate as many fruit branches as possible, and it is better to combine winter pruning with summer pruning. In winter, the competitive branches, dense branches and cross branches with upright back are pruned, and the non-main branches and cross branches are pruned to promote them to branch and cultivate into fruiting branches; Summer pruning removes dense planting and some overgrown branches on the back.
