Nowadays, pepper is added to many dishes, and the dishes produced by doing this tend to taste much better. Many people prefer to put some in it when cooking. There are more and more people planting Jiuyeqing pepper trees, so how do you prune this type of pepper trees? Next, let me tell everyone!

How to prune the nine-leaf green pepper tree?

1. The pruning effect of nine-leaf green pepper tree

Nine-leaf Green Zanthoxylum bungeanum can be properly shaped and pruned in Summer, which is conducive to the strong skeleton, clear layers, strong branches, reasonable structure, strong photosynthesis, good ventilation, and reduce pests and diseases. It can increase the yield, increase the age of the tree, and improve the quality. The increase in output can reach more than 35%.

How to prune the nine-leaf green pepper tree?

2. Pruning method of nine-leaf green pepper tree

1. Sapling pruning techniques

Pruning at the young age of Zanthoxylum bungeanum, achieving the pruning management method of "fixing the stem in one year, fixing the branches in two years, and setting the shape in three years", lays the foundation for increasing the continuous growth of Zanthoxylum bungeanum production.

(1) The first year fixed pole trimming (one year fixed pole)

The first year after planting Zanthoxylum bungeanum is the fixed stem. The height of the fixed stem is determined according to the cultivars, site conditions, cultivation methods, planting density, etc. The stem height is usually fixed from mid-May to early June, and the stem height is above the ground. Cut at 50 to 60 cm, and there are 4 to 5 full buds within 10 to 15 cm under the cut after the rod is fixed.

(2) Plastic pruning in the second year (fixed branches in the second year)

After the saplings are fixed, the focus is to cultivate the first-level main branches. When the main branches grow to about 30-40 cm, the core should be topped to control the growth of the branch tips. Choose 3 to 4 side branches on each main branch (2 Grade lateral branch), when the new branch grows to 50 cm, lightly pull the branch or press the branch in late October, and perform the topping in December to control the growth of the branch tip, and cultivate the fruiting branch and the fruiting branch group;

(3) Plastic and pruning in the third year (three years of shaping)

Focus on cultivating the extended branches and side branches of the main branch, and cultivate the fruiting branch and the fruiting branch group. Choose the extended branches on the secondary main branch in mid-June for short cutting of the strong branches, cut the base length of 15-20 cm, and cut off all the weak branches to make the main branches grow in a balanced manner.

2. Fruit tree pruning technology

After 3 to 5 years of planting, Zanthoxylum bungeanum grows vigorously. The main reason is to master the tree body shaping and pruning is the key, handle the auxiliary branches well, and cultivate the fruiting branch group in a planned way. The retention length of the backbone branches and the extension branches is 50-100 cm, and the branch angle is 45 degrees. The main branches maintain uniform growth through pruning. The pruning method can adopt techniques such as heavy cutting, short cutting, retraction, slow release, etc., to make the tree structure reasonable, make full use of light, and regulate the production of nutrients, the accumulation of nutrients, and the transfer and distribution of water. , Promote the effective balance of photosynthesis and respiration, guide vegetative growth and reproductive growth, adjust the reasonable ratio of vegetative branches and fruiting branches, prevent the fruiting parts from moving out, make the crown framework firm, achieve high yield, high quality, low consumption, and strengthen the tree body The purpose of anti-stress management, and can improve the quality of pepper, prolong the fruiting period, reduce the damage of disease and insects, and delay the senescence of the pepper tree.

3. Pruning technology during the abundance period

The focus of early pruning of Zanthoxylum bungeanum is to update and adjust the various fruiting branch groups of Zanthoxylum bungeanum to maintain its growth and fruiting ability, and to handle the extension branches and lateral branches on the backbone branches, and to rebalance them according to their growth position, space and growth strength. Cutting, short cutting, retracting, slow release and other techniques, appropriately removing dense clumping branches and branches that have no room for development, and by pulling branches (pressing branches), pinning, thinning branches, etc., to achieve good ventilation of the whole pepper tree , Adequate light, strong branch group, high yield and stable yield.
