2, plastic surgery (natural and happy appearance). The trunk is 20-40cm high, and the trunk branches (3-4 branches) are scattered on the trunk. The branching angle of the main branch is 30-50 degrees, and 2-3 auxiliary main branches are left on each main branch. Generally, after the third main branch is formed, the central trunk of this kind is cut off and twisted to one side to form a fruiting branch group.
Step 3 trim. (1) Young trees: mainly light pruning. After selecting the extension branches of the class center and the main branches and the extension branches of the auxiliary main branches, moderate or even severe pruning is carried out, and the growth balance among the main branches is adjusted according to the pruning degree and the direction of cutting buds. In addition to properly thinning the over-dense branches, the inner branches and weaker branches in the middle and lower part of the crown should generally be retained. (2) Initial fruiting stage: continue to select short cutting to treat the trunk extension branches at all levels, erase the summer shoots, and promote the autumn shoots to be robust. In autumn, measures such as ring cutting, root cutting and water control are taken to promote the flowering of Wangshu. (3) Full-fruiting period: the fruiting branches, falling branches and declining branches are retracted in time, and the light-blocking branches, dead branches and insect branches are cut off.
