A Complete Guide to Jujube Tree Pruning Methods and Technical Key Points
Jujube trees need branch and leaf pruning during their growth, as this can improve the yield and quality of the jujube trees. So how should jujube trees generally be pruned? What are the points that particularly need attention when pruning? What is the best time to prune? What are the pruning methods? Correct pruning methods are very beneficial to the growth of jujube trees. Let us learn about them together below.
1. Pruning Time
Jujube tree pruning is generally divided into winter pruning and summer pruning, and of course supplementary pruning is sometimes carried out in spring. Winter pruning is generally carried out during the period after the jujube tree sheds its leaves and enters dormancy, but if we speak of the specific pruning time, it is generally March and April as well as May and June.. Winter pruning must be done early; if pruned too late, it will affect the growth vigor of the jujube tree; summer pruning requires attention to timing, because pruning too early will fail to achieve the effect of regulating the jujube tree's fruiting branches.
2. Pruning Principles
The pruning principles for jujube trees need to be divided according to different time periods, mainly including the pruning principles for neglected trees, the pruning principles for young trees, the pruning principles for fruiting trees, and the pruning principles for aging trees. For neglected trees, the main approach is to keep the main trunk and branches, clear out messy branches, carry out gradual improvement, until a complete tree shape is formed. Young trees are generally subjected to trunk determination and shaping; for fruiting trees, it is branch pruning and shaping, regulating the distance between the main trunk, fruiting branches, and the overall tree shape, and pruning water sprouts, old branches, diseased and pest-infested branches, and dense branches; for aging jujube trees, the branches and leaves are renewed and new fruiting branches are cultivated.
3. Pruning Methods
There are many methods for pruning jujube trees. For different growth stages and different growth conditions of jujube trees, the pruning methods we adopt are also different, so as to ensure the normal growth of the jujube trees. The main pruning methods include ten pruning methods: the thinning method, the heading-back method, the renewal pruning method, the pinching method, the delayed pruning method, the bud notching method, the branch bending method, the bud removal method, the bud removal method, and the girdling method. We need to use pruning methods according to specific circumstances. If pruning methods are used improperly, this will also have a huge impact on the production volume of jujube trees.
4. Jujube Tree Pruning
During the early young tree period of jujube trees, their growth speed is relatively slow, so we need to promote branch growth. Then it is necessary to prune away all excess branches and leaves, keep only the main trunk and branches, and when the main trunk and branches have grown to a certain extent, promote the later growth of side branches to form an open-shaped crown. For jujube trees entering the fruiting stage, the main purpose is to ensure the yield and quality of the jujube trees, so it is necessary to prune away weak-growing, non-fruiting or low-fruiting, and diseased and pest-infested branches and leaves, reasonably control the tree shape, and cultivate thick and strong fruit-bearing mother branches. For jujube trees in the aging stage, we need to divide pruning into three modes: light renewal, medium renewal, and heavy renewal, scientifically cultivate new fruiting branches, and maintain the yield of the jujube trees.
The above are the key points about jujube tree pruning techniques that the editor wants to share with everyone today, hoping to help everyone. Under normal circumstances, if everyone carries out scientific pruning according to this method, the yield and quality of jujube trees can be correspondingly guaranteed.
