Last Updated: 2024/11/06, Pull the branch and open the corner. For the more upright branches, we can change the direction by pulling branches, disperse the growth polarity, slow down the vegetative growth momentum, and enhance the ventilation and light transmission of the tree. Get rid of cuteness and pick the heart. For the newly germinated useless jujube head, it can be erased from the base when there is no room for development, leaving only 2-3 jujube hangers at the base. ...

For the renewal of the old jujube tree, the long and thin branches should be rejuvenated; the dry and withered branches and thin branches that have no use value should be removed; the old wounds or stumps of broken branches should be trimmed with stubble and coated with protective agent. Specific pruning varies from tree to tree. 1. If there are no secondary backbone branches available in the middle and lower parts of the large branches, two layers of main branches are selected according to the sparse layer shape or 4 to 5 main branches are selected according to the round head shape, and each branch is retracted from 2 × 3 to 1 × 2. If there is no branch under the saw, a upright or oblique jujube should be left, and a short cut at the base of the jujube should be selected as a pruning branch. Second, if the old branch is not too bald, it is best to retain the two-level backbone branches of the main branch and the lateral branch, and then retract the main and lateral branches according to the above method. Third, the big branches and trunks are damaged and cannot be used, but the big branches with good roots can be sawed off from the flat ground to make them sprout. It can grow to more than 1.5 meters in that year, which is faster than replanting young trees. Remove its sprouting in summer, leave one or two sprouting tillers temporarily, speed up wound healing, and cultivate soil to protect it from breaking or damage. No matter which method is adopted for the renewal of old trees, the management of soil, fertilizer and water should be strengthened.
