Reasonable pruning of date palm trees.

Pruning methods

There are five commonly used: branch thinning, retraction, short cuts, centering, carving.

1 ⒈ branch thinning: the canopy dry branches, can not be utilized in the long branches, drooping branches and overcrowded branches to the base of the pruning method to get rid of. Thinning can play a role in making the tree nutrient concentration, moderately sparse, ventilation and light, balanced branch potential.

Peake retraction: the extension of branches, fruiting branches of the shrinkage. It can raise the angle of the branch head, growth potential, and is conducive to the restoration of the branch group and the old tree renewal.

Short cut: the longer branches cut short, the role is to increase the lower part of the nutrients, stimulate the main buds sprouting, and promote its new branches, to ensure that the tree is strong and normal results.

Sung hearting: in the growing season will be newborn jujube head top buds removed, jujube head lengthening growth, improve the fruit rate.

Be careful with sung wounds: that is, 1 cm above the main bud sung wounds, to promote the sprouting of new branches, generally do not bring with them, in order to save trouble to short cuts.

One of the reasons why jujube trees should be shaped and pruned:

(1) Pruning is an important technical measure in jujube tree cultivation, through shaping and pruning you can cultivate a solid skeleton and good tree structure, adjust the individual and group structure of jujube trees, improve the utilization rate of light energy, create a better microclimate conditions, and use space and easy to operate more efficiently. Utilization of space and easy to operate.

(2) Reasonably regulate the branch volume of the tree, control the growth of branches, improve the ventilation and light conditions of the tree and the distribution of nutrients in the body, so that the branches and leaves of each part have good light conditions and can fully carry out photosynthesis.

(3) Through pruning to make nutrient branches and fruiting branches into each other, to achieve rapid growth of young trees, improve results. The fruiting period is prolonged, and the old tree is renewed, prolonging the fruiting life. To achieve early results, early yield, reduce pests and diseases and stable production of high-quality purposes.

Two, jujube pruning time and attention to the main points:

1. The first fruiting period of jujube tree in pruning is mainly to reduce nutrient consumption, improve yield, so pruning should be the center of the trunk, the main side branches and large fruiting branches outside the dense development of the branch sparsity, there is space to retain, cut off the top bud.

2. Fruitful date palm is mainly to maintain good ventilation and light conditions of the canopy, so that the branch density is appropriate, so that the fruiting branches of a large number of results and planned fruiting branching system of rejuvenation and renewal, so that the fruiting branches to maintain the results of a longer life. The specific methods of pruning: First, remove the long, whorled, cross, concurrent, overlapping large branches; second, thinning, cut off weak branches and overcrowded branches; third, on the backbone of the large branches to stop the top and the appropriate retraction; fourth, to cultivate strong fruiting branches and fruiting mother branch.

3. The result of the renewal period is mainly to delay the tree aging, delay the results, so more retraction method, part of the sagging backbone branch to be retracted, the other weak branches also retracted accordingly. Generally retracted to the strong vitality of the date strand buds. After retracting the backbone branch to promote the birth of new jujube head, can be gradually cultivated into the main branch extension branch and lateral branches, enrich the inner chamber to supplement the space. If there is a newer branch on the backbone branch, it can be directly retracted to the newer branch.
