Pruning method of annual prickly ash tree
Annual Zanthoxylum bungeanum is a young tree, which can be pruned every autumn from harvest to defoliation. Specifically, it is carried out from September to 65438+ 10 every year. At this time, the climate is warm and humid, and the wound healing speed of Zanthoxylum bungeanum after pruning is faster, and the yield after pruning is higher.
When pruning the Zanthoxylum bungeanum tree for one year, thinning and cutting can be adopted, and only the branches of Zanthoxylum bungeanum tree with a length of 30-50 cm need to be kept, and then the branches are cut off from the trunk, which is also beneficial to pruning and modeling, thus promoting the formation of the crown of Zanthoxylum bungeanum tree. In addition, branches should be thinned, and branches with poor overlap, diseases and pests, weak branches and branches that affect the growth of trunk should be trimmed.
After pruning, add water to the pepper. Sprinklers can be used to spray water on the roots of Zanthoxylum bungeanum to keep the soil slightly wet. Pay attention to flooding when watering, otherwise the roots of Zanthoxylum bungeanum will be difficult to absorb, which will affect the later growth and development.
After the pepper is pruned, it should be supplemented with nutrients in time. After pruning, nitrogen fertilizer or fertilizer rich in phosphorus and potassium fertilizer can be applied once every 20 days to make pepper absorb sufficient nutrients. Pay attention to dilute the fertilizer with water before use, so as to avoid the high concentration of fertilizer and affect the normal growth of pepper.
