Management techniques of Zanthoxylum bungeanum in Spring

Zanthoxylum bungeanum is an important economic tree species, now it is a wealth project in many areas, there are seeds in many areas, and in order to ensure the high yield and high quality of Zanthoxylum bungeanum trees, we have to pay special attention to the management every spring. Let's take a look at the spring management techniques of Zanthoxylum bungeanum trees with the editor.

1. Fertilizing and spraying fertilizer

The growth and development of Zanthoxylum bungeanum trees are of high quality and need to absorb a lot of prevention from the soil, so in addition to applying base fertilizer immediately after picking, topdressing should be applied twice in spring and summer, the first time in April-May, with a small amount of nitrogen fertilizer, the second fertilization is in June-July, the first available chlorine fertilizer is applied, mixed with a small amount of phosphorus and potassium fertilizer, in order to promote high yield. Fertilization can take the methods of hole application and annular ditch application, dig holes in the crown dripping place, and cover the soil immediately after fertilization to avoid volatilization of fertilizer effect. In addition, after Xiehua, immediately spray dihydrogen phosphate foliar fertilizer 2-3 times, which can play an excellent effect.

2. Shaping and pruning

The old and weak trees are suitable for pruning in spring, while the young trees with exuberant growth can be pruned in summer. Spring pruning mainly adopts the methods of pulling, pressing, supporting and supporting to open the main branch angle. Old trees should pay attention to renewal and rejuvenation, make full use of overgrown branches, and properly re-cut weak trees to grow during the stimulation period. Summer pruning is mainly aimed at coring and shortening of overgrown branches to reduce nutrient consumption as much as possible and to remove dense branches in time for ventilation and ventilation.

3. Ploughing and weeding

When the soil is cultivated to prevent freezing in winter, it should be cut open in time after the temperature rises in spring, and at the same time, the tree plate should be re-planed to increase the water content of the soil under the tree crown. The size of the tree disk is close to that of the tree crown, and the soil at the root neck should be piled high in the rainy season to prevent excessive accumulation of water. Zanthoxylum bungeanum trees are afraid of grass shortage, so it is common to plough and weed once after the beginning of spring. at the same time, weeding work should be carried out several times in the growth process throughout the year to prevent grass famine. weeds should be dug and buried after drying to increase soil fertility.

4. Pest control

Diseases and insect pests are a major obstacle in the production of Zanthoxylum bungeanum, which directly affects the yield and quality of Zanthoxylum bungeanum, so it is necessary to do a good job in the detection and control of diseases and insect pests from spring to reduce the harm caused by diseases and insect pests as much as possible.
