Winter Zanthoxylum bungeanum Management

A "cut" is a plastic trim. Winter is a good season for pepper pruning, in pruning must cut off "seven branches", namely: excessive long branches, dry branches, pest branches, over-dense branches, cross branches, overlapping branches, thin branches. Then burn the pruned branches together to eliminate the pests and germs that overwinter on the branches. By pruning Zanthoxylum bungeanum, the tree vigor can be adjusted, the life span of Zanthoxylum bungeanum can be prolonged, and the yield and quality of Zanthoxylum bungeanum can be improved.

The second "scraping" is to scrape off the rough skin. In the thick bark cracks of pepper tree parasitic many eggs winter, tree trunk parasitic mulberry white shell. Scrape off the rough skin and glue spots, concentrated burn, and then wipe with glue Wei, Solibal pesticides, and then smear mud to cover the wound, can eliminate germs and eggs. Adopting this method also has the effect of rejuvenating the tree. In cold regions, it should be carried out in spring.

Three "painted", is the trunk painted white. White coating can reduce freezing injury, delay the germination and flowering of pepper trees, and protect pepper trees from late spring frost. In addition, it can also kill overwintering eggs and germs hidden in the bark. Pesticides applied to tree trunks include "highly effective whitening agents", which are extremely effective.

The fourth "spray" means spraying pesticides. Some pathogens and eggs can live through the winter in branches of trees besides living through the winter in litter and weeds. Therefore, spray Solibal pesticide to "99" before pepper tree germinates, preferably spray before pepper leaves fall, the control effect is excellent. At the same time, other trees around the pepper garden should also be sprayed to prevent the spread of pests. Five "Qing" is the green pepper garden. Some bacteria and eggs of pepper trees live through the winter on dead branches and rotten leaves. In winter, the sundries in the pepper garden can be cleaned up before turning over the garden, and the concentrated burning can eliminate overwintering germs and eggs.

The sixth "Shi" is to change soil and fertilize. To prickly ash tree base dig open old soil to see root, cut off diseased root. Sprinkle root rot powder pesticide, and then replace with new soil buried well, can prevent root rot. Then under the pepper crown using ring shape, radial, strip shape fertilization method, apply farm manure, phosphorus, potassium fertilizer, appropriate nitrogen fertilizer.

Seven "turn", that is, turn pepper garden. Under the natural conditions of low temperature and drought in winter, the overwintering pests in the soil can be turned out to freeze to death or be eaten by birds by turning over the garden. The depth of the garden is 20-25 cm. It is best to do this before the soil freezes. Turning pepper garden can not only eliminate overwintering pests, but also improve soil physical and chemical properties, improve soil structure and improve soil moisture conservation ability in winter.

8 "Water" means winter watering. In the "March 9" season, to pepper watering enough winter water, can play a warm and safe winter and increase nutrition, improve tree resistance.
