Regeneration and rejuvenation of main branches. The slender backbone branches at the top should be retracted, and the degree of retraction depends on the growth of the branches. The weak shrinks slightly, the weak shrinks again, and shrinks to the strong branch. The lateral branches should be moderately retracted to maintain the basic balance of the tree.
Regeneration and rejuvenation of fruiting branches. The middle branchlets should be thinned first, the remaining branches should be weakened and retained, and the branchlets should be retained. Large fruiting branches retract to the middle and back, and those that are of no use value should be thinned out. At the same time, we should pay attention to the cultivation of back branches.
