Introduction of pruning time and pruning techniques of Zanthoxylum bungeanum trees

Zanthoxylum bungeanum is a widely planted plant, very drought-resistant, like light. Zanthoxylum bungeanum seeds can not only be used as flavoring agents, but also medicine, with cold, insecticidal and other effects. Pepper tree planting process often through pruning to improve yield, etc., let's take a look at pepper tree pruning time and pruning technology points.

1. Pruning time of pepper tree

Zanthoxylum plastic pruning, can be divided into two general winter pruning and summer pruning. From the pepper tree after defoliation to the next year before germination of a period of time for pruning called winter pruning, also known as dormant pruning. Pruning during the growing season is called summer pruning, also known as growing season pruning.

In winter, pepper tree nutrients gradually transported from the leaves to the branchlets, back to the big branches and then to the backbone, and then from the trunk to the root system transport. Before budding in spring, these nutrients are transported to branches and buds in the opposite direction to the above, for budding and flowering.

The methods of pruning in summer include opening angle, bud wiping, bud removal, branch thinning, topping, twisting, branch taking and cutting, etc., which are applied under different conditions.

2. Key points of pruning technology of prickly ash tree

The main role of pepper tree pruning is to facilitate growth and fruit, improve yield. Second, pruning can improve lighting conditions and prevent pests and diseases. Pepper trees in the pruning to grasp a principle: less main branches, branchlets and more. Generally, 3~5 main branches can be left, and the branchlets are fruit branches, so that the branch groups and lateral branches are reasonably evenly distributed.

1. pruning of old trees

First remove diseased branches, dry branches, then trim inward branches, cross branches, overlapping branches, and finally cut off the top of each branch around the crown by 10 cm. Old trees and weak trees pruning, mainly to renew rejuvenation, heavy contraction or thinning out small branches group. Make full use of the long branches, supplement the incomplete crown, and maintain the appropriate fruiting area.

2. Pruning of adult fruiting pepper trees

When pruning fruit trees, to maintain the tree vigor robust, mainly regulate the amount of flowers. When the branches are densely crowded, they should be mainly sparse, the upper part should be sparse and the lower part should be sparse, and the redundant large branches affecting the light should be removed to maintain good ventilation and light transmission conditions. For over-dense, thin, cross, excessive growth and diseased branches, it is also necessary to remove them in time to make the branches in the crown healthy, balanced, ventilated and transparent. Pay attention to keep branches evenly, and don't be bald at the rear.

3. Pruning of young trees and early fruit trees

Seedling planting in the winter of the year or the second year in the base 25~30 cm, cut off the top; the first fruit of young trees plastic and fruit pay equal attention to, pruning should be light, generally not short, only some support, pull and curved branches. Keep good backbone branches, cut off redundant branches, germinate branches at the base to keep good main branches 3~5, the rest cut off from the base.
