After selecting the main stem branches, the branches that are too dense and crowded, the branches that grow together and the branches that grow in parallel will be thinned. Meanwhile, pull the branches. Whether it is pruning in winter or normal pruning, it is the key to the full bloom of Zanthoxylum bungeanum. After six or seven years of growth, Zanthoxylum bungeanum can enter the full fruit period, and the trimmed Zanthoxylum bungeanum tree can reach 10-20 years. In the full fruit period, Zanthoxylum bungeanum will bear a lot of fruits, and the inner branches of the plant are very prone to lack of nutrients and aging, and the bottom of the technical backbone branches will also be exposed.
Zanthoxylum bungeanum is in full fruit stage, and pruning in winter is mainly shortened. When pruning, remove unnecessary, weak and useless long branches and adjust the tree type. Fine management and pruning of dense, sparse, cross and diseased branches can reduce unnecessary nutrient consumption, make robust branches have sufficient growth space and shape new fruit branches. Conclusion Unnecessary long branches should be gradually removed and plastic surgery should be carried out in tree pruning. Fine pruning of branches in the crown, mainly thinning branches, thinning out insect branches, cross branches, overlapping branches, dense branches and blind branches, creating good conditions for natural ventilation and light transmission of the trunk.
For fruit branches, we should compromise, overlap and occupy space for the weak, ensure that the branches are symmetrical inside and outside, and can reach into the fist everywhere, which is conducive to harvesting peppers, combined with the methods of cutting, pulling, pressing back and putting fruit branches. For the prosperous branches with indoor space, cut them lightly first, and then compromise for the weak in the coming year to shape them into branches. For old trees, thinning is the leading factor, long branches are drawn, weak branches are removed, big buds are left, root-promoting fruit branches are updated in time, old ones are removed and small ones are left, and weak ones are left strong, so as to repair plant types. In order to reduce the consumption of nutrients in flowers and trees and improve the fruit setting rate, buds can also be smeared after the trees germinate, and the flourishing branches, blind branches and heavy branches can be removed. Bud wiping is beneficial to the natural ventilation and light transmission of flowers and trees.
