Management methods of jujube in winter

The cultivation area of jujube in our country is very large, there are many varieties, and it is also welcomed by many people in our country. Jujube is rich in nutrients, such as vitamin C, vitamin P and so on, which is very beneficial to human health. When planting jujube trees, the winter management needs our attention. So how to manage jujube in winter? Let's take a look at the management methods of jujube trees in winter with Xiaobian.

1. Clear the garden in time

Most varieties of jujube have been harvested in winter. Therefore, the first thing we should do well in winter is to clear the garden. First of all, we should take all the fallen branches, rotten fruits and weeds out of the jujube garden to burn. Then do a good job of soil preparation, the soil should be fine and deep turn, can improve the structure of the soil, promote the root system of jujube, enhance its growth ability. Then it is necessary to do a good job of disinfection in the whole garden to eliminate the bacteria and eggs lurking on the soil trunk so as to ensure the normal growth of jujube trees in the second year.

2. Application of base fertilizer

In winter, we should also apply sufficient base fertilizer to the jujube garden, which is also the key to ensure the annual yield of jujube trees. The general base fertilizer is mainly rotten farm manure, combined with the right amount of ammonia bicarbonate. In the deep turning of the jujube garden, the application depth of the general base fertilizer should be controlled at about 30 cm. The application time should be after autumn harvest until before the fallen leaves of jujube trees. The amount of fertilizer application should be controlled according to the actual situation such as tree age and growth, and water should be properly watered once after fertilization. The main fertilization methods are ditch application, such as annular ditch, radiation ditch and so on.

3. Shaping and pruning

Shaping and pruning is also an indispensable management work for jujube trees in winter. Pruning will directly affect the growth of jujube trees in the second year. First of all, we need to cut off the branches of diseases and insect pests, overlapping branches and competitive branches, so as to improve the photosynthetic capacity of jujube trees and avoid consuming too much nutrients. Then the aged branches, erect branches and other branches should be retracted to balance them to enhance the growth of jujube trees and cultivate fruiting branches. Finally, the jujube head of the one-year-old jujube should be truncated properly to prevent the jujube head from growing too long and affecting the results of the second year.

4. Pest control

Pest control also needs our attention in winter. In addition, we should also scrape off the old skin and warped skin on the trunk of jujube trees, which can not only control diseases and insect pests, but also stimulate the growth of trees. After scraping the trunk, the trunk should be properly painted white, which can protect against cold and heat preservation, and eliminate germs and insect eggs. Finally, when we clear the garden, we also need artificial insect control to eliminate the latent overwintering adults and ensure that jujube trees survive the winter safely.

The above is a brief introduction to the winter management of jujube trees. That's all for today's introduction. This article is for reference only. I hope it can help you all.
