1. The opening branch angle of saplings, the main sapling branch and the large auxiliary branch opening angle in the growing season, not only can make the branch angle fixed, lay a foundation for a large number of results, and can ease the tree potential, branching potential, and promote flower bud formation. The base angle is 45 degrees, the waist angle is 50 to 60 degrees, and the tip angle is 60 to 70 degrees.
2. Twisted shoots cultured branches, when the tip of the new shoot is semi-lignified, the twisted shoots have a significant effect of inhibiting prosperous growth and promoting flowering. However, the tip should not exceed 1/10 of the total number of back branches.
3. Lighten the trees and improve the light. When the crown canopy is closed, some dense shoots or unusable leggy branches can be removed to improve lighting. When paying attention to the branches, keep straight to stay oblique, and stay strong until you leave.
4, short-term promotion of crown expansion, when the saplings at all levels of branches up to 40 to 50 centimeters, a short cut and remove the excision under the 1-2 leaves, promote three branches, increase the short-term branches, in order to facilitate the expansion of the crown .
