Zanthoxylum bungeanum pruning is one of the main techniques for high yield and high quality of Zanthoxylum bungeanum. Reasonable pruning can make the tree skeleton firm, well-defined, strong branches, sufficient light and good ventilation, improve the yield and quality of pepper, and prolong the life of pepper. Zanthoxylum bungeanum is characterized by its strong branches and good fruit. Because Zanthoxylum bungeanum has many branches and scattered nutrients, the fruiting branches tend to grow weakly, the ability to sit tall is weakened, the ear is small and light, there are many branches, the crown is dense, the indoor light is poor, and the branchlets are more dead. These can be adjusted by pruning. How to trim peppers?

(1) pruning time. After grazing, but before germination in the following spring. Pruning is the best in harvest season, which is conducive to improving light, accumulating nutrients and enriching flower buds, as well as easing tree vigor and preventing germination. But it also depends on the specific situation. It is better to cut down young trees in autumn and old trees and weak trees after sleep.

(2) Renovating trees.

① Natural happy shape. After planting, leave a trunk of 30 cm, select 3-5 main sides at the top and 50-60 degrees at the bottom, and cultivate 2-3 lateral branches for each main branch. The bearing edges and branches on the main side are evenly distributed. This kind of tree has the highest yield, good quality and long life, so it should be cultivated from an early age.

② Nerve plexus. After planting, cut off the stem, extract many branches from the root and neck, or plant 2-3 plants in a hole and grow naturally. This kind of tree has a fast crown and early yield, but it has too many trunks, crowded branches, poor illumination and short life.

8 round head type. There is an obvious trunk, and many main branches are naturally distributed on the trunk, and the branchlets are crowded with light rain, so it is difficult to harvest.

Of these three kinds of trees, nature is the best, but it should be cultivated from young trees.

(3) Pruning methods should be flexibly mastered according to different tree shapes and different tree ages.

(1) young trees. Pruning should pay equal attention to shaping and results. At 1 year after planting, the stem is fixed at about 30-50 cm from the ground. After germination in the second year, the sprouting branches at the base of the tree are removed, and 3-5 main branches are selected, with a short cut of 1/3, and the first lateral branch is selected about 30 cm away from the main branch. Finally, remove the branches in the middle and cut them into happy crowns.

② Middle-aged trees that have been shaped and started to bear a lot of fruits. It is necessary to gradually remove the redundant big branches in the crown, cut off pests and diseases, cross branches, dense branches and long branches, and create conditions for ventilation and light transmission in the crown. As a result, the branches should be weakened and staggered to occupy space, so that the inner and outer branches are uniform. First, lightly prune the flourishing branches with vigorous growth space, then remove the strong branches and keep the weak branches in the second year to cultivate the bearing branches.

③ Old and weak trees. It is mainly about sparse and recovery trees. It is necessary to remove old branches and leave branchlets, sparse weak branches and leave strong branches, and choose strong branches and strong buds to restore tree vigor. On the one hand, attention should be paid to the utilization of long branches, and at the same time, the skeleton should be updated alternately, which not only ensures the yield, but also restores the tree potential.

In addition, in order to reduce the nutrient consumption of the tree, it is necessary to cut off the sprouting branches at the base of the tree, as well as the vigorous branches on the back of the branches, long branches and twigs below the branches in time.
