Zanthoxylum bungeanum can be pruned during the whole dormant period from defoliation to budding, and can also be pruned in summer. Pruning after picking pepper can improve light transmittance, enhance nutrient accumulation and promote pepper bud differentiation. Winter pruning should start after the sap stops flowing, which can reduce nutrient loss.

Pruning method of pepper

1, short-cut pruning

The common pruning method of Zanthoxylum bungeanum is short pruning, which mainly cuts off vigorous branches and aging main branches to make them grow more lateral branches. Cut off 2/3 of the main branches and keep only 2~3 main branches, which can reduce nutrient consumption and promote the healthy growth of plants.

2, refinement

In order to promote the flowering and fruiting of pepper, thinning is needed. When pruning, it is necessary to cut off the base, dense, overlapping, crossing and weak branches of branches to make them better ventilated and transparent, and promote the fullness and richness of pepper effect.

3, the old tree pruning

After the aging of Zanthoxylum bungeanum, the tender branches, drooping branches and dead branches should be cut off at this time, which can reduce the consumption of nutrients, promote the growth of healthy branches and prolong the life of Zanthoxylum bungeanum.

4, multi-branch pruning

When pruning multiple branches, 4~5 strong branches should be selected for cultivation, and the rest branches can be cut off. In the second year, all the lateral branches on the main branch should be trimmed until 4~5 main branches are fixed. This pruning helps plants to fully absorb nutrients and avoid unnecessary nutrient consumption.
