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 pepper tree? 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 firm 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%.

2. Nine-leaf green pepper tree pruning method

1. Sapling pruning techniques

Pruning at the young age of Zanthoxylum bungeanum, to achieve 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 production.

(1) The first year fixed pole trim (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 fixed stem height is usually fixed from mid-May to early June, and the fixed 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 fixing the pole.

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

After the saplings are fixed, the focus is on cultivating the first-level main branches. When the main branches grow to about 30-40 cm, they should be topped to control the growth of the branch tips. Select 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 topping in December to control the growth of branch tips, cultivate the fruiting branches and the fruiting branch group;

(3) Plastic trimming in the third year (three-year 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 to short cut 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 cut, short cut, retract, 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, extend the fruiting period, reduce the damage of disease and insects, and delay the senescence of the pepper tree.

3. Pruning technology during the abundance

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 deal with the extension branches and lateral branches on the backbone branches, and to rebalance them according to their growth position, space and growth strength. Cut, short cut, retract, slow release and other techniques, appropriately remove dense clumping branches and branches that have no room for development, and adopt measures such as pulling branches (pressing branches), pinning, and thinning branches to achieve good ventilation of the whole pepper tree , Adequate light, strong branch group, high yield and stable yield.
