It consists of three main branches, the first branch faces south, the second and third branches are evenly distributed in the northeast and northwest respectively, and the opening angle of the main branch is 50 ~ 60. 2 ~ 4 lateral branches are left on each main branch, which are arranged in the air, spread at an angle of 60 ~ 80 degrees, and extend on multiple axes, on which various bearing branches are planted. The whole crown is round.

② Plastic surgery technology. After planting, the stem was fixed at 60 cm, and three main branches were selected without the central stem. When cutting in winter, cut the extension branches of the main branches by 50 ~ 60 cm, and cut the rest branches slowly or slightly. In the winter and spring of the following year, control the re-coring of competitive branches and upright branches on the back, continue to open branches, and select 2 ~ 3 lateral branches for each main branch extension branch.
