Young jujube trees have few branches and slow growth. Under the condition of neglect of pruning and laissez-faire management, it tends to extend uniaxial and grow vertically, resulting in poor tree structure, slow formation, small fruiting area and late fruiting, which affects yield and benefit. Therefore, pruning of young trees should be done well on the basis of promoting vigorous growth. The effect of pruning on promoting growth varies with varieties, pruning periods, parts and methods. Therefore, the pruning of young trees should take corresponding measures according to the characteristics of varieties, different site conditions and planting methods.

The branching ability is different among different varieties and varieties of the same type with different growth. Under general cultivation conditions, jujube varieties and short-crowned jujube varieties naturally branch earlier, usually 3-5 years old, and after short cutting, they can promote more branches, with larger base angle, but finer branches; Among jujube varieties, it usually takes 5-6 years for trees to branch. After short cutting, the number of branches is small, the base angle is small, but the branches are thick.

The branching ability and growth intensity of jujube branches are different at different ages. 1 year-old branches can generally produce more branches after being cut short; Perennial branches, including 2-3 years old branches, are also difficult to branch.

The branching ability and natural branching ability of jujube trees after pruning are not only related to varieties, but also to the strength of trees. Strong branches and individual plants have strong natural branching ability, and there are many branches after short cutting; The natural branching ability of weak growth branches and individual plants is weak, and there are fewer branches after short cutting.

When pruning young trees, corresponding measures should be taken according to the different reactions of pruning. The 1 year-old branches of young jujube trees are particularly sensitive to pruning. After short cutting, the branches are thick and branched. Therefore, the pruning time of young jujube trees, mainly annual branches, should be determined according to different requirements. In addition to pruning in winter, attention should also be paid to pruning in summer, but the pruning of 1 annual branches should be less sparse and light. For the secondary branches that can be selected as main branches and lateral branches, the main buds on the base 1 ~ 2 jujube stocks can be used to promote the growth of branches, increase the number of branches and expand the crown without loosening the secondary branches; When pruning perennial branches, the secondary branches on the branches should be thinned, and the parts that need to be branched should be cut or carved to promote the growth of branches. The suitable time for girdling is from germination in spring to elongation and growth of jujube head for about half a month, which requires strict time and has poor overdue effect. Pruning perennial branches should not only pay attention to the branching characteristics of varieties, but also pay attention to the thickness of branches. For varieties that are easy to branch, such as Jinsixiaozao, the thickness of perennial branches suitable for pruning is relatively small, generally around 1.5 ~ 2.0 cm; For varieties that are not easy to branch, such as jujube, the thickness of perennial branches suitable for pruning should be between 2.0 and 3.0 cm. This has a great effect on promoting the growth of lateral branches, and attention should be paid to pruning.
