How to manage jujube trees in winter? Detailed explanation of the latest methods
The cultivation area of jujube trees in our country is very large, with a great many varieties, and they are also very popular among many people in our country. Jujubes contain very rich nutritional elements, such as vitamin C, vitamin P, etc., which are very beneficial to human health. When planting jujube trees, winter management is something we need to pay special attention to. So how should jujube trees be managed in winter? Now let's take a look together with the editor at the winter management methods for jujube trees!
1. Timely orchard cleaning
In winter, most varieties of jujube trees have already finished harvesting. Therefore, in winter the first thing we need to do well is the orchard cleaning work. First, we should gather all the fallen branches and leaves, diseased and rotten fruits, and weeds in the jujube orchard and take them out of the orchard in a centralized manner to be burned. Then we should do a good job of land preparation. The soil should be finely and deeply plowed, which can improve the soil structure, promote the deep rooting of the jujube tree root system, and enhance its growth capacity. Then we should do a good job of disinfecting the whole orchard, eliminating the pathogens and insect eggs lurking on the soil and tree trunks to overwinter, ensuring that the jujube trees can grow normally the following year.
2. Application of base fertilizer
In winter we should also apply sufficient base fertilizer to the jujube orchard. Base fertilizer is also the key to ensuring the yield of jujube trees the next year. Generally, the base fertilizer is mainly decomposed farmyard manure, combined with an appropriate amount of ammonium bicarbonate. It should be applied together with the deep plowing of the jujube orchard. Generally, the application depth of the base fertilizer should be controlled at about 30 cm. The application time should be after the autumn harvest and before the jujube trees shed their leaves. The amount of fertilizer applied should be controlled according to the actual conditions such as tree age and growth vigor. After fertilizing, water should be applied appropriately once. The fertilization method is mainly trench application, such as ring-shaped trenches, radial trenches, etc.
3. Shaping and pruning
Shaping and pruning is also an indispensable management task for jujube trees in winter. Whether the pruning is done well or not will directly affect the growth of jujube trees the following year. First, we need to cut off branches such as diseased and pest-infested branches, crossing and overlapping branches, and competing branches, thereby improving the photosynthetic capacity of the jujube tree and avoiding excessive consumption of nutrients. Then, branches such as senescent branches and upright branches should be retracted to balance them and enhance the growth vigor of the jujube tree, cultivating bearing branch groups. Finally, appropriate heading back should be carried out, cutting back the one-year-old jujube heads of the extension branches, to avoid the extension growth of the jujube heads being too long and affecting the fruiting the following year.
4. Pest and disease control
Pest and disease control is also something we need to pay special attention to in winter. Doing a good job of orchard cleaning also has the effect of preventing and controlling pests and diseases. In addition, we should also scrape off the old bark and loose bark on the jujube tree trunks, which can not only prevent and control pests and diseases but also have the effect of stimulating tree growth. After scraping the bark of the trunk, the trunk should be appropriately whitewashed, which can prevent cold and preserve warmth, and also eliminate pathogens and insect eggs. Finally, when cleaning the orchard, we should also carry out manual pest control, eliminating adult insects lurking to overwinter, ensuring that the jujube trees overwinter safely.
The above is a brief introduction to the winter management methods for jujube trees. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
