In the winter of the first year or the second year of seedling planting, the top of the trunk is cut at 25-30 cm; Young trees with initial fruits should pay equal attention to shaping and fruiting, and the pruning amount should be light, generally not short, only supporting, pulling and bending branches. Keep the main branches, cut off the redundant branches, keep 3-5 main branches at the base, and cut off the rest from the base.

Young trees and fruit trees should be pruned in autumn, weak trees and old trees should be pruned in spring. When pruning, it is a powerful measure to cut off dead branches, over-dense branches and insect branches first, and burn the insect branches centrally, which is to prevent and control pepper tree rot, leaf rust, root rot, Gideon, gall midge and red shank disease.

These are the pruning techniques of Zanthoxylum bungeanum, and the best pruning time is after harvesting in autumn. Pruning branches in winter is easy to freeze and dry up, and pruning in spring is easy to reduce production due to excessive bleeding. When pruning, we must pay attention to the combination of thinning and shrinkage, cut less and shorter, weaken the retention, and sparse and strong buds.

Zanthoxylum bungeanum, as one of the delicious raw materials for cooking, must be pruned to keep the fruit harvest. Then let's learn the pruning technique of pepper shaping.

Trimming method of plastic surgery

There are three kinds of plastic trees: open-heart type, double-layer open-heart type and cluster type. The seedling height is 40-60 cm, and there are more than 6 full buds under the incision 10- 15 cm. In the first half of June, after the stem is shaped, the new shoots can grow to 30-40 cm. Select three main branches and core all other new branches. The three main branches are evenly distributed, with a spacing of about 15cm and a horizontal included angle of about 120. The opening angle of the main branch should be about 40, and the length of the main branch is generally 35-45cm. In the second year, the elongated branches are cut short, with a length of 45-50 cm. Select the first lateral branch on the main branch, which is 30-40 cm away from the main branch. The lateral branch should be selected on the oblique flat side or the oblique upper side, and the horizontal angle between the lateral branch and the main branch is 50. In the third year, the length of the second side branch of each main branch is 50-60 cm, and the second side branch must be on the opposite side of the first side branch, with a spacing of 25-30 cm, preferably on the oblique upper side or the oblique flat side, and the included angle of the second side branch should be 45-50.

Shaping and pruning technology

1. Pruning of old trees: firstly, remove pests and dead branches, then prune inward branches, cross branches and overlapping branches, and finally cut off the tops of branches around the crown 10 cm. The pruning of old and weak trees is mainly to renew and rejuvenate, and the weak branches are reduced or thinned. Make full use of the long branches, supplement the incomplete crown, and maintain an appropriate bearing area.

2. Pruning of the mature pepper tree: When pruning the pepper tree, it is mainly to keep the tree vigor and adjust the flower amount. When the branches are dense, they are mainly sparse, and the upper branches are sparse and the lower branches are slow, and the extra large branches that affect the light are removed to maintain good ventilation and light transmission conditions. For branches that are too dense, too thin, too cross, too prosperous or sick, they should also be thinned in time to make the branches in the crown strong, balanced, ventilated and transparent. Pay attention to leave branches evenly and don't be bald at the back.

3. Pruning of young trees and newly hung fruit trees: in the winter of that year or the second year of seedling planting, the top of the trunk is cut 25-30 cm; Young trees with initial fruits should pay equal attention to shaping and fruiting, and the pruning amount should be light, generally not short, only supporting, pulling and bending branches. Keep the main branches, cut off the redundant branches, keep 3-5 main branches at the base, and cut off the rest from the base.

Young trees and fruit trees should be pruned in autumn, weak trees and old trees should be pruned in spring. When pruning, it is a powerful measure to cut off dead branches, over-dense branches and insect branches first, and burn the insect branches centrally, which is to prevent and control pepper tree rot, leaf rust, root rot, Gideon, gall midge and red shank disease.

These are the pruning techniques of Zanthoxylum bungeanum, and the best pruning time is after harvesting in autumn. Pruning branches in winter is easy to freeze and dry up, and pruning in spring is easy to reduce production due to excessive bleeding. When pruning, we must adopt corresponding pruning methods according to different varieties, tree ages and tree vigor, pay attention to the combination of thinning and shrinkage, cut less and shorter, weaken the retention strength, and sparse weak buds to retain strong buds.
