The latest key points of Zanthoxylum bungeanum overwintering management

Zanthoxylum bungeanum is a very popular side dish in some provinces of China, and it is also a kind of traditional Chinese medicine, which is very beneficial to human health. Therefore, now the planting area of Zanthoxylum bungeanum is also relatively large, and because the cold resistance of Zanthoxylum bungeanum is relatively poor. Therefore, in winter, the overwintering management of Zanthoxylum bungeanum is very important. So how should Zanthoxylum bungeanum survive the winter? The following editor brings you the key points of the overwintering management of Zanthoxylum bungeanum trees. Let's have a look!

1. Tree management

Before entering winter, we should first whiten the trunk of pepper water. Trunk whitening can effectively eliminate the bacteria and eggs lurking on the trunk. It also has a strong reflective ability, which can reduce the temperature difference between day and night as much as possible. When painting white, paint the whole tree trunk white, always the place where the dirt bifurcates. At the same time, we can also spray appropriate amount of protective agent on leaves, branches and tree trunks. For example, amino acid foliar fertilizer, Antaisheng, etc., can close the stomata of branches after spraying, avoid consuming too much water and cause striping phenomenon, but also delay the flowering period of prickly ash trees and enhance their cold resistance.

2. Smoke and cultivate the soil

In winter, it is usually around 11:00 in the evening, which is the coldest time. At this time, we can smoke and prevent the cold in the garden, and we can use sawdust, fallen branches and leaves as the main fuel to cover it together to form a dark fire, so that the whole garden is covered with thick smoke. But we should pay attention to control the fire and smoke position, avoid being too far away from the pepper tree to cause burns, but also pay attention to the fire. Then cultivate the soil at the base of the tree trunk, the diameter is controlled at about 1 meter, and the height of the soil is about 15 cm, mainly to protect the roots and avoid serious freezing damage. After entering the spring, remove it in time and raise the ground temperature.

3. Pruning the covered tree disk

In early winter, we should prune the fallen pruning trees, especially those within two years, and do a good job of cutting off their tips. Avoid excessive consumption of the tree, improve the accumulation of nutrients in the tree, so as to enhance the cold resistance of prickly ash tree. Then we can cover the tree plate with rice straw, corn straw and other grain stalks around the tree plate. It can not only preserve soil moisture, but also improve the ground temperature. At the same time, plastic film or leaves should be laid within one meter around the trunk, which can effectively reduce the frost injury of prickly ash trees.

4. Irrigation and water conservation in winter

After entering the winter, the soil is very easy to freeze at night and become diurnal. So we should dig trenches between the rows of the pepper trees, and then pour enough water along the ditches. Make sure that water can fully penetrate into the soil before nightfall. In this way, the water we pour in winter can be used in spring. Avoiding the phenomenon of spring drought is also very beneficial to the growth and development of pepper water. Moreover, water also has the function of storing temperature, which can ensure the relative balance of ground temperature and reduce freezing damage in winter. After winter irrigation, it is necessary to cover the grass in time and hoe properly to avoid water evaporation too quickly.
