How to prun the nine-leaf green pepper tree?

Nowadays, peppers are added to many dishes, and the flavors of these dishes tend to be much better. Many people like Jiuyeqing peppers prefer to put them in the dishes. There are more and more people planting nine-leaf pepper tree, so how is this pepper tree pruned? Next, the editor will tell everyone!

How to prun the nine-leaf green pepper tree?

1. Pruning effect of nine-leaf green pepper tree

Nine-leaf green prickly ash is pruned by reasonable shaping in summer, which is conducive to the strong skeleton of the prickly ash, clear layers, strong branches, reasonable structure, strong photosynthesis, good ventilation, and reduction of pests and diseases. The rate of increase can reach more than 35%.

Second, pruning method of nine-leaf green pepper tree

1. Pruning techniques for young trees

Zanthoxylum bungeanum pruning at a young age, to achieve a "one year fixed pole, two years fixed branches, three years fixed shape" pruning management method, to lay the foundation for increasing the continuous growth of pepper output.

(1) Fixed pole trimming in the first year (fixed pole for one year)

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

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

For young trees after pole fixing, the focus is on cultivating first-level main branches. When the main branches grow to about 30 to 40 centimeters, topping is required to control the growth of the shoots. Select 3 to 4 side branches on each main branch (two Grade side branches), when the new branches grow to 50 cm, lightly pull the branches or press branches in late October, and topping in December to control the growth of the shoot tips, cultivate the fruiting branches and fruiting branch groups;

(3) Plastic trimming in the third year (three-year shaping)

Focus on cultivating the extension and side branches of the main branch, and cultivating the fruiting and fruiting branches. Choose the extended branches on the second-level main branches in mid-June for short cuts of strong branches. The base length of the shear is 15-20 cm, and the weak branches are all cut off to make the main branches grow in a balanced manner.

2. Results tree pruning technology

Zanthoxylum bungeanum grows vigorously after 3 to 5 years of planting. The main reason is to master the tree shape and pruning is key, handle the auxiliary branches, and cultivate the fruiting branches in a planned manner. The retention length of the extended branches of the backbone branches is 50-100 cm, and the branching angle is preferably 45 degrees. The main branches are kept uniform by pruning, and the pruning method can adopt techniques such as heavy truncation, short truncation, retraction, and slow release to make the tree structure reasonable, make full use of light, and adjust the production of nutrients, the accumulation of nutrients and the transfer of water. , Promote the effective balance of photosynthesis and respiration, guide vegetative growth and reproductive growth, adjust the reasonable ratio of nutrient branches and fruiting branches, prevent the outward migration of fruiting parts, make the canopy skeleton firm, achieve high yield, high quality, low consumption, and strengthen the tree body The purpose of anti-adversity management, and can improve the quality of Zanthoxylum bungeanum, extend the life of the results, reduce the damage of pests and diseases, and postpone the aging of Zanthoxylum bungeanum.

3. Pruning techniques during high yield

The main point of pruning in the early stage of Zanthoxylum bungeanum is to update and adjust various fruiting branch groups of Zanthoxylum bungeanum to maintain its growth and fruiting ability, and to handle the extension and side branches on the backbone branch, according to their growth position, space and growth strength. Cutting, short cutting, retraction, slow release and other techniques to properly remove dense clumpy branches and branches with no development space, and through the measures of pulling branches (pressing branches), topping, thinning branches, etc., to achieve good ventilation of the whole pepper tree , The sun is abundant, the branches are strong, the purpose of high and stable yield.
