Bark is a very important protective layer for trees. If the bark is cut once in the process of planting, it will easily lead to the death of trees, and the time of death should be judged according to the tree potential.
After a tree is planted, if the bark around it is cut open, it will grow more vigorously at first, but the nutrient cycle will be destroyed after the bark is injured. Simply put, the nutrients in the root system can be transported to the branches and leaves, but the nutrients synthesized by photosynthesis in the leaves are difficult to flow back to the roots.

Precautions:
Generally, the trunk of jujube trees is selected for girdling, and the position is generally about 20 cm from the ground, so that the old bark on the outermost layer of jujube trees can be removed, and then the bark can be peeled off with a girdling knife, so that the xylem will not be hurt and the growth of jujube trees will not be affected when girdling.
Fruit trees are not allowed to grow freely. Sometimes human intervention, such as pruning, bud removal and grafting, aims to make fruit trees grow better and improve fruit yield and quality.
When girdling jujube trees, the girdling degree should be determined according to the actual growth of jujube trees, and the width should not exceed 1cm as far as possible. If it exceeds the tolerance of the tree, it will do harm to the tree, but it will reduce the number of flowers.
