During the growth of Zanthoxylum bungeanum, it is necessary to do a good job of coring, and remove the top shoots in time before its new buds grow white. Mainly to promote the secondary growth of branches and accelerate the formation of crown. Picking the heart in time in mid-May is beneficial to flower bud differentiation. Then, it is conducive to pollination and fruit setting before the pepper tree falls down, and it is also conducive to the expansion of pepper fruit, promoting growth and early maturity. It can also inhibit the growth of branches and ensure the robust growth of branch buds.

2, thinning branches

Branching is mainly about thinning the branches at the base of Zanthoxylum bungeanum, and the thinning parts are mainly the old, weak, dead, overlapping and excessively long and dense branches of Zanthoxylum bungeanum. Thinning branches is beneficial to reduce nutrient consumption, improve permeability, enhance the growth ability of internal branches of Zanthoxylum bungeanum, and promote photosynthesis and flower bud differentiation. Thinning branches in the New Year can also prevent the phenomenon of big and small years in Zanthoxylum bungeanum. When the thinning branches are large, it is not appropriate to thinning all at once to prevent the wound from being too large and reduce the growth of pepper. But also lead to infection, cause various diseases and insect pests, and make the branches grow white.

3. Injured branches

The main purpose of injured branches is to reduce the growth of top branches, promote the growth of lower and inner branches, help flower bud differentiation and improve the flowering and fruiting rate. Before spring germination, Zanthoxylum bungeanum should be circumcised above and below branches or buds and cut to the cortex. This can effectively hinder the nutrition and water transported in the lower part, which is beneficial to the growth of buds and the formation of strong branches. There are many ways to hurt branches, such as twisting branches and twisting tips. The main purpose is to control the downward transport of nutrients, improve the fruit setting rate and promote fruit growth.

4. Curved branches

The purpose of bending branches is to change the growth of transverse branches and drooping branches, which can reduce the growth rate of top branches. Limit the uniform speed of nutrition and water, prevent excessive growth of branches and reduce the growth of top branches. This can ensure that nutrients and water are concentrated on the robust fruiting branches, prevent uneven distribution of nutrients, and reduce the flowering and fruiting rate. And can effectively reduce the overgrowth of branches, prevent excessive consumption of nutrients and increase the planting cost.

Extended data:

It should also be trimmed properly. Zanthoxylum bungeanum will age when it grows to a certain age, so we need to cut off all the weak branches and old branches to make healthy branches grow better. We can also cut it short and cut it at two-thirds of the main branch, but we need to keep two or three branches so that the nutrients in the soil can be more concentrated.
