Plastic pruning is a very important technical measure in the cultivation and management of Zanthoxylum bungeanum. In the past, peppers were not pruned and allowed to grow naturally.
The crown is often closed, the branches are messy, and the ventilation and light transmission in the crown are poor, which leads to the breeding of pests and diseases. Trees gradually weaken, yield decreases and quality declines. In addition, pepper water pruning can be divided into three stages: summer, Xia Dong and winter pruning.
The importance of pruning
Pruning peppers in summer is extremely important, and the time should be sooner rather than later. First, from June to early July, pruning mainly focuses on harvesting flowers and peppers. Short-cut branches at the strong buds of 3 ~ 10cm, and cut off pests and diseases, dead branches, overlapping branches, cross branches, dense branches and twigs to promote the growth of latent branches. Second, in the middle and late July, the long branches were cut short or thinned at the fruiting branches of 10~20 cm, and the auxiliary branches of 5 ~ 15 were properly reserved, and the updated branches were reserved.
Dry Zanthoxylum bungeanum was mainly harvested in August, and branches of diseases and insect pests, dead branches, overlapping branches, crossed branches, dense branches and weak branches were mainly cut off, while auxiliary branches and updated branches were retained. Pruning in summer and winter is based on the growth of pepper trees, such as dewatering, dewatering, bud wiping or tip wiping. Careful pruning and clear goals depend on planting density, management level and tree length.
