1. Chemical control: spraying paclobutrazol, chlormequat chloride, etc. Two or three times at the peak of fruit tree growth can shorten internodes and dwarf plants.

2. Crown pruning: in the peak season, timely picking, branch pulling, tip twisting, bud wiping, etc. Conducive to controlling the type.

3. Ring peeling: peel off the part close to the trunk for a few centimeters, then peel off the short anvil skin of the same size and stick it on it, and wrap it.

4, multiple scratches: the trunk of the fruit tree is carved several times every 0.3 cm, and the roots are trimmed when the pot is put.
