1. Planting characteristics of pepper tree

Zanthoxylum bungeanum is a kind of tree that likes warmth and light. Higher temperature is very beneficial to the cultivation of Zanthoxylum bungeanum. It is also more resistant to cold and drought. Annual prickly ash seedlings or branches can survive at a low temperature of -18 ° C, and are most afraid of late frost during the germination period. Winter is most afraid of the cold current. In addition, Zanthoxylum bungeanum is resistant to waterlogging, but Zanthoxylum bungeanum can not accumulate water for a long time, it is easy to cause the death of the tree, and it is suitable for growing in fertile and humid sandy soil.

Second, the fertilization skills of pepper tree

1. Base fertilizer

The base fertilizer should be mainly organic fertilizers, such as compost, manure, green manure and crop straws. Organic fertilizer must be thoroughly rotted to avoid the spread of diseases caused by fertilizers. Then the non-fertile plots can be applied with quick-acting nitrogen fertilizer, increasing the fertilizer effect. Adequate nutrients are beneficial to their nutrient reserves, and they are very helpful for improving the yield and quality of Zanthoxylum bungeanum. After harvesting, fertilization is convenient to restore the tree vigor, and methods such as ring furrow and radial furrow can be adopted.

2. Top dressing

Generally, for rapid growth of Zanthoxylum bungeanum, it is necessary to add quick-acting fertilizers. From flowering and fruiting to fruit expansion, timely application of foliar top dressing can effectively increase yield. Spray urea and phosphate fertilizer at the flowering stage, spray urea at the full flowering stage, and spray phosphate fertilizer and urea aqueous solution at the fruit expansion stage. In addition, the ratio of the fertilizer concentration should not exceed 0.5%, otherwise it is easy to cause fallen leaves, flowers and fruits, resulting in reduced production.
