Topping. In the summer, the secondary branches selected for growth, such as excessive growth, can be topped when the secondary branches are not lignified, and the branches are promoted to cultivate the resulting branches. For example, if one result branch only produces one secondary branch, and the growth potential is strong, it will be short-cut in spring or summer, promote branching, and grow into the resulting branch group. The short-cut strength is moderate and mild. . When the growth of the secondary branches exceeds 30 cm, the topping is performed once more; when the roots are picked up again in July, the technical requirements are the same as above.
Short cut. Short and unpicked developmental branches can effectively increase branching and accelerate the process of shaping or the result of branching. However, the number of short new shoots should not be too much, and the parts should be staggered from each other, otherwise it will easily cause overlapping of branches.
Long branches. When the growth of the long branches is unreasonable and the growth potential is inferior to the adjacent main branches and side branches in the same direction, it should be removed from the base, or it can be properly preserved according to its space, and the results can be cultivated by short-cut and summer picking. Early walnuts have a large amount of branches, which tends to cause many litchi in the crown, and the density is too large, which is not conducive to ventilation and light transmission. In accordance with the principle of weakening and staying strong, we should promptly remove excessively dense branches. The method of thinning branches is to cut off the base of the stick, and the pile cannot be left to promote wound healing. Remove the pests and branches.
Open. It is advisable to not pick the heart or lightly cut the tip of the new shoot. The lighter the pruning, the more branches are formed and the fewer the number of secondary branches.
Pull the branch. When the branch is timely, the opening angle of the walnut backbone can be opened, and the canopy space can be fully utilized to promote the flowering and increase the fruit setting rate. The main branches are mainly the prosperous trees and the early fruit trees. The trees in the fruiting period are properly pulled, the single trees are pulled upright or the branches are small, and the branches are biased to fill the branches, and the weak branches can be pulled back. High angles allow it to grow normally, and trees that open at an angle and flattened branches do not need to be pulled.
Lychee, take the branch. Soften the branches for shaping, then pull the branches or slings, hang the bottles, hang the bricks and press the branches, change the angle of the branches, and place the branches in a suitable position. When the main branch is pulled, the rope is smashed in the middle of the branch and opened at an angle of 60 to 70 degrees; the auxiliary branch is flattened at an angle of 80 to 90 degrees. After the branches are pulled, they should be evenly distributed around the crown of the tree. After the branches are pressed for 50~60 days, they are basically shaped. At this time, the rope can be released or the bottles, bags, bricks, etc. can be removed.

Uv absorbers are the most widely used light stabilizers, which can be divided into salicylate, benzophenone, benzotriazole, substituted acrylonitrile and triazines according to their structure. The most widely used light stabilizers are benzophenone and benzotriazole in industry. Quench agent is mainly metal complex, such as divalent nickel complex, and often used with ultraviolet absorber, play a synergistic effect.
