What are the methods for dealing with overly dense branches and fine dense branches

After jujube trees enter the full fruiting stage, the fruiting branch groups tend to become flat and droop, and the fruiting branch groups on the upper side of the main and secondary branches easily overlap with the branch groups below, causing excessive density that affects ventilation and light penetration. The branches within these branch groups that grow downward and have low fruiting capacity can be thinned and cut back to improve light conditions. In addition, many thin and weak vegetative branches often sprout on the outer part of the canopy, sometimes without secondary branches, or with only 1 to 2 short, thin secondary branches. During winter pruning, such thin and weak branches should be thinned out to reduce the shading of light by the outer branches, benefit fruiting throughout the tree, and make the tree's nutrients relatively concentrated, promoting renewal growth.
