Pruning is a very important technical measure in pepper cultivation and management. Pruning of Zanthoxylum bungeanum can not only promote the growth of branches, make the distribution of branches more reasonable, but also make full use of space, improve lighting and nutrition conditions, and improve the quality and yield of Zanthoxylum bungeanum. So, how to prune a three-year-old pepper tree? What are the pruning methods for peppers? Today, we are going to learn about pepper pruning.

1. Pruning law of Zanthoxylum bungeanum. The pruning of pepper should pay attention to the tree shape. Mainly depends on the current growth of pepper, according to its growth, to determine the weight and degree of pruning, rather than the same.

2. Three-year pruning of Zanthoxylum bungeanum for young trees and fruiting trees, it is more appropriate to prune Zanthoxylum bungeanum after harvesting in autumn and before defoliation. Pruning at this time can prevent the problems of slow wound healing, excessive wound flow and reduced fruit yield after pruning in spring.

The general principle of Zanthoxylum bungeanum pruning is to reasonably distribute the positions of main branches and lateral branches to form a better fruiting branch group, which can effectively increase the yield and reduce the risk of Zanthoxylum bungeanum diseases. In the third year, Zanthoxylum bungeanum has generally formed first-class lateral branches, so we should pay attention to the selection and retention of main branches and first-class lateral branches, and pay attention to the regulation and pruning of competitive branches; In the third year, we will continue to cultivate the main branches and lateral branches, and at the same time do a good job in selecting, retaining and cultivating the main branches and lateral branches, auxiliary branches and fruiting branches.

When pruning Zanthoxylum bungeanum, 3 ~ 5 main branches can be left, and the branches are fruiting branches, and the branch groups and side branches need to be distributed reasonably. In the third year, cut the secondary branches of each main branch into 50 ~ 60 cm long, and the secondary lateral branches must be horizontally distributed in the opposite position of the main branch with an interval of 25 ~ 30 cm. When pruning, carefully cut off dead branches, dead branches and diseased branches first, and deal with them in a unified and centralized way.

The main purpose of pruning small trees for three years is to frame the tree. For example, to maintain a natural and happy shape, we need to consider the development direction of the three main poles on the first floor and the reserved position of the secondary pole. The general requirement is 3 main and 6 trunk 12 heads. The diameter of the formed crown shall not exceed the row spacing.
