Plants whose branches have just begun to decline can fully shrink and shrink the aging branches when pruning in winter. It is incomplete, and the result is that the branches with few basic branches are sparse on the basis. Cut off other aging eggplant populations 1/3 ~ L/2, and concentrate nutrition to promote new branches. Jujube branches are fragile and prone to droop. Shrink drooping backbone branches, improve branch angle and increase growth momentum. The shrinkage is one-third or two-fifths of the length of the backbone network. For the 1~3-year-old developmental branches sprouted in the museum, according to the space size, several secondary branches are left short to cultivate medium branchlets.

As a result, most branches died and the front end of the trunk began to wither. In addition to the aging and death of a large number of branches and insufficient removal, it also aggravated the contraction of the whole trunk system (including central dryness). Generally speaking, it should be reduced to 1/3 ~ 1/2 of the length of the original interosseous branch, but it should be noted that the sawing diameter of the contracted part should not exceed 5 cm. During this period, the growth momentum of trees decreased obviously, the roots died, the crown shrank, the dead branches in the pipes increased and the yield decreased. Jujube wine is very big, but jujube is smoked less. New jujube heads will germinate only if they are strongly stimulated. Generally, jujube trees enter the senescence period after 80 years, and the single plant will not begin to decline until more than 100 years. During this period, pruning is officially started, and new stem branches and new fruiting branches can be cultivated by using the jujube heads germinated by Enya buds at the lower part of the stem branches, gradually replacing the original test tubes and maintaining a certain yield.

Judging from the jujube age, it is characterized by fruiting time and local multiple updates, which are closely related to varieties, environmental conditions and cultivation techniques. As long as we master this rule, we can strengthen management and pruning according to the characteristics of jujube trees. It can accelerate the formation of water pipes, advance the fruiting and prolong the economic life of fruiting time. The pruning of jujube trees should be based on different trees, densities and varieties.

Dry fruit varieties often have strong fruit-bearing ability in the same year. Therefore, cutting, rewinding and renewing eggplant in time can improve the variety and its continuous fruit-bearing ability (such as pear and jujube). The quality of coarse fruit is slightly poor, mainly depending on the varieties of mature jujube wine. Generally, it is best to adjust the vegetative growth of trees by wiping buds, wiping branches and removing stones, so as to achieve high and stable yield. For example, Lingwu Jujube, Huang Can Jujube and so on. Jujube tree cultivation technology old tree pruning technology germination, strong branch strength varieties, short and low shrinkage strength, germination, low branch strength varieties should be short and high shrinkage strength. This can better adjust the number of new branches and keep the balance of tree potential.
