The pruning policy of "promoting first and then controlling, blocking, twisting and pulling" should be strictly implemented in the pruning of dwarf and dense planting of jujube trees.

Before promoting and after controlling: in the early growth stage of jujube (1-2 years), jujube should be promoted as soon as possible to form a crown. Post-control: When the crown is basically formed (3 years later), crown control measures should be taken to control crown expansion and promote its results.

Insertion: Take measures such as retraction and coring to control the growth of crown height, which is generally controlled at about 2-2.5m.. Put it down: when the jujube tree bears fruit, take measures such as short cutting to promote the germination of new branches at the lower part of the jujube tree.

Supporting branches: in the process of shaping young trees, use wooden sticks to support branches with small bottom angle and suitable direction to an ideal angle.

Branch pulling: It is to pull the valuable branches to a certain angle and orientation with wire or rope.

Extended data:

Jujube pruning is divided into two stages: winter pruning and summer pruning. In early childhood, plastic surgery is the main task, the skeleton is set up well, and the backbone branches are arranged reasonably, which provides the foundation for a good lighting environment. The tree shape of jujube is mainly evacuation, stratification and happiness.

The first secondary branch under the cutting bud should be thinned, otherwise it may not play the role of short cutting. When the crown is enlarged enough to leave lateral branches, lateral branches should be equipped on the main branches, and lateral branches should be left where there is space.

Generally, 2 ~ 3 lateral branches are left on each main branch. The pruning of lateral branches is similar to that of main branches, that is, the first secondary branch is thinned when it is full of buds. Where there is space on the lateral branches, main branches and central trunk, the built-in fruiting branches are reasonably arranged to achieve the balance between growth and fruiting.

Pruning is mainly light pruning, and trees with disordered trees should be updated year by year to avoid excessive pruning at one time, otherwise it will easily lead to excessive growth and destroy the balance between growth and fruit. After the adult tree, it is mainly to distribute the fruiting branches reasonably and make full use of the light, and it is not advisable to prune the backbone branches too much.
