Management techniques of Zanthoxylum bungeanum in autumn and winter

The picking of Zanthoxylum bungeanum is coming to an end, and this is the critical period for controlling diseases and insect pests and reducing the amount of overwintering pests. Therefore, we should pay attention to the following management techniques:

First, for pepper gardens with serious damage to Zanthoxylum bungeanum, shell insects, rust and so on, the trees should be sprayed 1-2 times with a mixture of 1000 times 15% trimethrin, 1000 times isocarbophos and 1000 times cyhalothrin.

Second, clean up dead trees and deciduous weeds in time, burn them centrally, and eliminate the sources of diseases and insect pests.

Third, farmers who need to build pepper gardens or replant seedlings should choose pepper seedlings, choose rainy days and plant with leaves to ensure the survival rate.

Fourth, seize the time to apply base fertilizer in autumn, the specific method is: flat pepper trees can use ring fertilizer method, ring depth 30-40 cm, width 40 cm, generally 1-4-year-old trees, each tree 20-30 jin of soil fertilizer and 0.5-1 jin of nitrogen, phosphorus and potassium compound fertilizer; more than 4-year-old trees apply 40-50 jin of soil fertilizer and 1-2 jin of multi-component compound fertilizer. For pepper trees planted on slopes or ridges, the amount of fertilizer applied per plant is less than that on flat land.

Fifth, seriously do a good job in the shaping and pruning of Zanthoxylum bungeanum trees and improve the ventilation and light transmission conditions of pepper gardens, so as to improve the yield and quality of pepper.

Sixth, do a good job of pepper drainage to prevent pepper trees from flooding and death.
