Key points of wintering management of prickly ash tree

Pepper in some provinces of China is a very popular side dish, but also a Chinese herbal medicine, human health is very beneficial. Therefore, the planting area of pepper trees is also relatively large, and because the cold resistance of pepper trees is relatively poor. Therefore, in winter, the winter management of pepper trees is very important. So how does the pepper tree winter? The following small series brings you the key points of winter management of pepper trees. Let's have a look together!

1. Tree management

Before entering winter, we should first deal with the trunk of pepper water to do white treatment. Trunk whitewash can effectively eliminate latent in the trunk of the winter bacteria and eggs, etc. And also has a strong reflective ability, can reduce the temperature difference between day and night as much as possible. When painting white, paint the whole trunk white, all the way to the place where the mound branches. At the same time we can also spray the leaves, branches and trunk of the right amount of protective agent. For example, amino acid foliar fertilizer, Antaisheng, etc., can close the stomata of branches after spraying, avoid excessive water consumption and thus appear the phenomenon of shooting, but also delay the flowering of pepper trees, enhance their cold resistance.

2. Fumigation and soil cultivation

In winter, it is usually around 11 pm, which is the coldest time period. At this time, we can smoke and cold-proof in the garden. We can use sawdust, fallen branches and leaves as the main fuel to cover them together to form a dark fire, so that the whole garden is covered with thick smoke. However, attention should be paid to controlling the position of fire and smoke, avoiding being burned too far away from pepper trees, and paying attention to fire. Then at the base of the trunk to cultivate soil, diameter control at about 1 meter, the height of the cultivated soil is about 15 cm, mainly to protect the roots, to avoid serious freezing damage. After entering spring, remove it in time to improve the ground temperature.

3. Trim the cover tree tray

In the early winter, we have fallen leaves of pepper trees, especially within two years of the tree, to timely pruning, do a good job of cutting tips. Avoid excessive tree consumption, improve the accumulation of nutrients in the tree, thereby enhancing the cold resistance of pepper trees. Then we can also cover the tree tray with straw, corn stalks and other grain stalks around the tree tray. It can not only preserve soil moisture, but also improve ground temperature. At the same time, plastic film or leaves should be laid within one meter around the trunk, which can effectively reduce the freezing damage of pepper trees.

4. Irrigation and water conservation in winter

After entering winter, the soil is prone to night freezing and day melting. So we should dig trenches between pepper trees and pour plenty of water along the trenches. Ensure that moisture penetrates the soil well before nightfall. In this way, the water we irrigate in winter can be used in spring. Avoid spring drought phenomenon, the growth and development of pepper water is also very beneficial. Moreover, water also has the function of temperature storage, which can ensure the relative balance of ground temperature in winter and reduce freezing damage. After winter irrigation, it is necessary to cover the grass in time, and it can be shallowly hoe properly to avoid excessive evaporation of water.

The above is a brief introduction to the winter management points of pepper trees. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
