Pruning time
Pruning of jujube trees is generally divided into winter pruning and summer pruning, and sometimes supplementary pruning is carried out in spring. Winter pruning generally refers to the dormant period of jujube trees after defoliation, but the specific pruning time is generally March, April and May and June. Winter pruning must be done as soon as possible. If it is too late, it will affect the growth of jujube trees; Pay attention to the time when pruning in summer, but premature pruning can't adjust the bearing branches of jujube trees.
Pruning principle
Pruning principles of jujube trees need to be divided according to different periods, including the pruning principles of laissez-faire, young trees, fruit trees and old trees. Let the tree go with the flow, mainly by putting the main branches aside, cleaning up the messy branches and gradually improving them until a complete tree is formed. Young trees usually have a fixed trunk shape; Pruning and shaping fruit trees, adjusting the distance between the trunk and fruit branches and the whole tree, pruning long branches, old branches, pest branches and dense branches; Old jujube trees should renew their branches and cultivate new fruiting branches.
Pruning method
There are many pruning methods for jujube trees. According to different growth periods and different growth conditions, different pruning methods are adopted to ensure the normal growth of jujube trees. Pruning methods mainly include thinning branches, cutting short, retracting, pinching branches, slow release, cutting buds, pulling branches, smearing buds, smearing buds and opening nails. We need to use pruning methods according to the specific situation. If the pruning method is not used properly, it will also have a great impact on the production of jujube trees.
Jujube pruning
The growth rate of jujube trees in early and young age is relatively slow. In order to promote the growth of branches, it is necessary to trim all the redundant branches and leaves and keep the main branches. When the main branch grows to a certain extent, it can promote the growth of lateral branches in the later stage and form an open crown. In order to ensure the yield and hostages of jujube trees in the fruit-bearing period, the branches and leaves with weak growth, no fruit or little fruit, diseases and pests should be pruned, the tree shape should be controlled reasonably, and the solid mother branches should be cultivated. In view of the aging period of jujube, it is necessary to divide it into three pruning modes: mild regeneration, moderate regeneration and severe regeneration, so as to scientifically cultivate new fruiting branches and maintain jujube yield.
