Eight key points of Zanthoxylum bungeanum Management in Winter

A "cut" is plastic surgery and pruning. Winter is a good time for pruning Zanthoxylum bungeanum. "Seven branches" must be cut off when pruning, that is, long branches, dry and withered branches, disease and insect branches, overdense branches, cross branches, overlapping branches, and slender branches. Then the cut branches will be burned in the collection, which can eliminate the overwintering pests and germs on the branches.

The second "scraping" means scraping off the rough skin. In the thick skin cracks of the pepper tree, there are many parasitic eggs overwintering, and mulberry is parasitic on the trunk. Scrape off the rough skin and glue spots, focus on burning, and then rub on Liujiawei, Solibar pesticides, and then apply mud to cover the wound, can eliminate germs and eggs. Taking this method also has the function of rejuvenating the tree potential.

The third "painting" is the white painting of the tree trunk. White coating can reduce freezing damage, delay the sprouting and flowering of pepper trees, and protect pepper trees from the harm of late frost in spring. In addition, it can also kill overwintering eggs and germs hidden in the bark. The pesticides applied to tree trunks are "efficient whitening agents", which are extremely effective.

The fourth "spray" is to spray pesticides. In addition to overwintering on litter and weeds, some bacteria and eggs can also be parasitic in tree branches and other parts. Therefore, Solibar is generally sprayed on "99" insecticides before pepper germination, and it is best to spray when the leaves of pepper are not falling, and the control effect is excellent. At the same time, spray other trees around the pepper garden to prevent the spread of diseases and insect pests.

The fifth "Qing" is the Qingjiao Garden. Some germs and eggs of pepper trees overwinter on dead branches and rotten leaves. In winter, the sundries in the pepper garden can be cleaned and burned centrally before turning the garden, which can eliminate overwintering germs and insect eggs.

The sixth "giving" is to change the soil and apply fertilizer. Cut open the old soil to see the root on the base of the pepper tree and cut off the diseased root. Root rot disease can be prevented by sprinkling root rot pesticide and burying it with new soil. Then, under the canopy of Zanthoxylum bungeanum, the ring shape, radial shape and strip shape were used to apply farm fertilizer, phosphorus fertilizer, potassium fertilizer and some nitrogen fertilizer.

The seventh "turn" is to turn over the pepper garden. Making use of the natural conditions of low temperature and drought in winter, by turning the garden, the overwintering pests in the soil can be frozen to death or eaten by birds. The depth of turning over the garden should be 25 centimeters. It is better to do it before the soil is frozen. Ploughing pepper orchard can not only eliminate overwintering pests, but also improve soil physical and chemical properties, improve soil structure and improve soil moisture conservation capacity in winter.

Eighth, "watering" means watering in winter. When entering the "three Nine" season, pouring enough winter water on Zanthoxylum bungeanum can keep warm and safely survive the winter, increase nutrition and improve the resistance of trees.
