1. Zanthoxylum bungeanum, alias: sweet pepper, big pepper, green pepper, green pepper, mountain pepper, dog pepper, Sichuan pepper, red pepper, red pepper and Dahongpao. Zanthoxylum bungeanum seedlings are light-loving, suitable for warm and wet loam and sandy loam with deep soil layer, with strong sprouting, cold resistance, drought resistance, strong disease resistance, long life of hidden buds and strong pruning resistance.

2, not tolerant of waterlogging, short-term water accumulation can be fatal. Pruning in summer is usually carried out 2-3 times a year, and its main function is to wipe off or sparse the overgrown branches, overgrown branches and slender branches on the back in time, and to sparse the sprouting branches under the trees, so as to improve the illumination, concentrate nutrition and increase the yield. ?

3. When pruning in winter, the lower branches of the trunk are thinned, and 3-6 upper branches are reserved as main branches. If the selection of 1 year is incorrect, it can be completed in two years, and the vertical branches in the middle become thinner. Cut the selected main branch 1/3, leaving strong buds. Select the first lateral branch 50 cm away from the trunk, then select the second and third lateral branches every 30-40 cm, and arrange them left and right. Over-dense fruiting branches are weakened and remain vigorous, so that the branches inside and outside the crown are not pressed, distributed evenly, and can be put into fists everywhere, with good illumination and easy harvesting.
