How to prune jujube trees in winter? Detailed explanation of the latest pruning techniques

Jujube is a fruit that we all enjoy eating very much, and it is basically cultivated in all parts of our country. When growing jujube trees, we need to do a good job of pruning as the seasons change. Among these, winter pruning is very important, as it directly affects the jujube tree's flowering, fruiting and other production performance the next year. So how should jujube trees be pruned in winter? Below, the editor has brought you three little tips for winter pruning of jujube trees. Let's take a look together!

1. Heading back

When pruning jujube trees in winter, we can first carry out heading back. Cut off the thin and weak secondary branches that grew later on the jujube tree, then keep the robustly growing secondary branches in the middle to enhance the jujube tree's production capacity. For auxiliary nurturing branches, follow the principle of first letting them grow and then cutting them back, to encourage them to bear fruit as soon as possible. Then we should also pay attention to tip heading, that is, when heading back the top of the jujube tree. Remove the first secondary branch below the cut, to encourage the main bud below the cut to sprout. Promote the growth of the main and lateral branches, and improve the fruiting area and the growth capacity of the main and lateral branches of the jujube tree the next year.

2. Retrenchment

Then we should also do a good job of retrenchment pruning, expanding the branch angle and ensuring balanced tree vigor. When retrenching, we can do it during the jujube tree's fruiting period. At the base of all main trunk branches, choose and keep two robust secondary branches growing in different directions, each retaining one bud eye, and then cut off the excess. But it must not affect the forward extension direction of the main trunk branches. After the jujube tree sprouts in spring, the retained bud eyes will grow new branches. When the new branches grow to about 75 cm, pinch off the tips, and then do a good job of branch bending to maintain the growth of the new branches.

After leaf fall, saw off the main trunk that extends forward, and the sawing position should be at the new branch. Doing so will not have a great impact on the jujube tree's yield that year. Then we can also shape the jujube tree according to the open-center method and adjust the jujube tree's framework. Select and keep secondary branches with appropriate growth direction and suitable angle. When retrenching, retain about two bud eyes to encourage new buds to sprout in spring. Then, when 7-8 secondary branches have grown, pinch off the tips and bend the branches.

3. Thinning branches

Thinning branches is also a pruning task that needs to be done well during winter pruning of jujube trees. Many jujube tree canopies are relatively closed, and the branches grow densely, resulting in extremely poor ventilation inside the canopy and insufficient light. This not only leads to reduced yield, but fruit quality is also greatly affected. Moreover, when carrying out management work such as spraying for disinfection, it is also very inconvenient. So when pruning in winter, we should pay attention to thinning out all branches with no useful value and affecting permeability, such as crossing and overlapping branches, thin and weak branches, and overly long and dense branches.

The above is a brief introduction to how to prune jujube trees in winter. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
