In the second year after the stem is fixed, 1 upright and stout branches are selected as the central branches, 3-4 branches with good directionality and appropriate angles are left as the main branches of the lower first layer, and the rest are all drained. After these branches grow vigorously, in the third to fourth year, the same branch promotion method as the fixed stem is used to make the main branches grow lateral branches and two-layer main branches. ? 1, the first fruiting period of jujube. Mainly to reduce nutrient consumption and increase yield. Therefore, the densely developed branches except the central trunk, main lateral branches and big bearing branches should be thinned and space should be reserved to cut off the terminal buds.

2. Jujube trees in full fruit. It is mainly to maintain good ventilation and light transmission conditions of the crown, make the density of branches and leaves suitable, make the fruiting branches bear a large number of fruits, and rejuvenate and renew the fruiting branches in a planned way, so that the fruiting branches can maintain a long fruiting life. Specific methods: first, remove long, alternating, intersecting, concurrent and overlapping branches; Second, thinning, cutting weak branches and too dense branches; Third, the top of the main branch stops and retracts properly; The fourth is to cultivate robust fruiting branches and fruiting mother branches.

Results The regeneration period is mainly to delay the senescence of trees and delay the fruiting, so the method of retraction is often used to retract some drooping main branches and other weak branches accordingly. Generally, it retracts to the rootstock bud with strong vitality of jujube trees. After the main branch is retracted, the new jujube head is pushed forward, which can be gradually cultivated into main branch extension branches and side branches, enriching the supplementary space in the inner room. If the updated branches are now on the main branch, they can be directly taken back to the updated branch.
