Now we are in the season of pepper harvest in early autumn, and we must prune it after harvest, that is, in winter (also known as dormancy). In addition, the pruning time in winter should be carried out within a period of time from the dead leaves of Zanthoxylum bungeanum to the germination of the next year. Young trees or pepper trees in high-yield period are more suitable for pruning after harvest in autumn, while old trees and weak trees are more suitable for pruning after germination in spring or summer. How to cut pepper trees in winter?

1. Can pepper be pruned in winter?

Pepper can be pruned in winter. The key of Zanthoxylum bungeanum is pruning in hibernation. During hibernation, most nutrients are transferred to the main roots and technical backbone branches for storage, and the nutrients destroyed by pruning at this time are the least. The common pruning methods of Zanthoxylum bungeanum in winter are short cutting, dewatering, shrinkage and spin drying. Must pay attention to take shortcuts, less detours, can shrink the merger.

Second, the pruning method of pepper

The key to pruning pepper must be carried out from two levels, one is shaping, and the other is pruning. The two must cooperate with each other. The standard of pruning is generally that pepper has fewer branches and more branchlets, because most of the mother branches of pepper are on branchlets.

In addition, from the description of the problem, most people can know that it is a pepper tree in the early fruit stage, and the pruning standard of such a pepper tree is "thinning". Because the pepper trees at this time are still in the period of continuous growth and development, it is necessary to thin branches to prevent excessive pruning from harming the growth and development of pepper trees in the middle and late stages, resulting in damage to the yield of pepper trees in the high-yield period.

At this time, Zanthoxylum bungeanum generally does not carry out plastic and cosmetic procedures such as shrinking branches, supporting branches, pulling branches and bending branches. Let the main stem of pepper grow and develop again, and cut off some unnecessary branches. Generally, the top four branches can be kept up and down, and the others can be cut off.

Branches that grow too densely can be thinned to adjust the sunshine level of pepper. Some branches of Zanthoxylum bungeanum processed repeatedly or in parallel can be selected, cut off and preserved. Generally, cutting off all the upright branches and keeping the flat branches can promote the growth and development of Zanthoxylum bungeanum and expand the indoor space. If you meet the upright branches with rich growth and development, you can shorten or pull branches or other branches.
