The girdling width: It should be 1/5 to 1/10 of the diameter of the trunk, usually 0.5 to 0.8 cm. The trees and Wangshou are more suitable, and the small and weak trees are narrower. Ring girdling method: first use a trowel to scrape the old skin of the girdling area, 0.7-1.1 cm wide to expose the phloem, then use a sharp knife to cut the skin in a circle, deep to the xylem, and then follow the girdling Width and then cut a circle, the tangent line should be straight, and finally the bast in the middle of the transverse incision can be removed. Stripping width should be based on tree trunk diameter 1/10 basis. When girdling, notice that the lower edge of the opening is slightly inclined outward. Post-stripping management: 3 to 5 days after peeling, apply spraying protection with 50% phoxim 50 to 100 times to the ring, and wrap it with paper or plastic film.
