"In the winter, the pepper trees gradually stop growing and are in a dormant state. Using the peppercorns during winter dormancy for winter tube has many advantages, especially for the prevention and control of pepper diseases and insect pests, saving labor and medicine, simple and easy to implement, and good control effect." November On the 15th, at the pepper planting base in Shibanliang Village, Xinzheng Town, Yilong County, agronomist Chen Guochang of the County Agriculture and Rural Bureau and technicians from the base were explaining the winter management techniques of pepper to pepper farmers. Chen Guochang said that the winter management technology of Zanthoxylum bungeanum mainly focuses on the following 5 aspects:
Pruning and clearing the garden
Winter is a good time for pruning and clearing the garden. During pruning, the "seven branches" must be cut off, namely: long branches, dry branches, diseased branches, dense branches, cross branches, overlapping branches, and delicate branches. The focus of pruning is the "retraction" of old trees, the "thinning" of strong trees, and the "cutting of stems" of trees. The specific operation method is to cut off the sprouted autumn shoots at the top of the old tree and cut off two-thirds of the weak branches. The purpose is to restore the tree vigor to control vegetative growth, promote reproductive growth, and achieve high yield in the coming year. The fruit-bearing period of about ten years mainly removes slenderness, crossover, overlapping and diseased branches. The purpose is to increase ventilation and light transmission, reduce nutrient consumption and overwintering pests, and improve the yield and quality of pepper. Then, the remaining branches and leaves that have been cut off in the garden are thoroughly cleaned up and burned in a concentrated manner, which can eliminate the overwintering pests and germs on the branches and trunks. By trimming and pruning the Zanthoxylum bungeanum, the tree vigor can be adjusted, the growth of the tree body can be promoted, the life span of the Zanthoxylum bungeanum tree can be prolonged, the yield and quality of the Zanthoxylum bungeanum can be improved, and the economic benefits can be increased.
Scratch the insect white
Scrape is to scrape off the rough skin. In the cracks of the rough bark of the pepper tree, there are many worm eggs that overwinter, and the trunk of the tree is parasitic with the mulberry white scale. The scraped rough skin and glue spots are burned together, and then rubbed with Liujiaowei and Solibal pesticides, and then smeared with thin mud to cover the wound, which can eliminate germs and eggs. Taking this method also has the effect of rejuvenating the tree. In alpine regions, it should be done in spring as well. Whitening can reduce freezing damage, delay the budding and flowering of the tree, and protect the pepper tree from the harm of late spring frost. In addition, it can kill overwintering eggs and germs hidden in the bark. The pesticides used to coat tree trunks have "high-efficiency whitening agents", which are extremely effective. At the same time, you can make your own whitening agent. The self-made whitening agent formula is quicklime, sulfur, and water with a mixing ratio of 10:1:80, which can also eliminate overwintering eggs and various germs at the base of the trunk.
Cultivating
Taking advantage of the natural conditions of low temperature and drought in winter, after the pepper is harvested and before the beginning of winter, the pepper garden is plowed, weeded, and soil is replaced. Through the garden, the overwintering pests in the soil are turned out to freeze to death or allow birds to feed. . The depth of the garden should be 20-25 cm, and it will behave well before the soil is frozen. Turning the prickly ash garden can not only eliminate the overwintering pests, but also improve the physical and chemical properties of the soil, improve the soil structure, and improve the ability of the prickly ash garden soil to retain water and moisture in winter.
Fertilization and irrigation
Fertilization time: after picking to before soil freezing. Fertilizer type and amount: organic fertilizer + biological bacterial fertilizer + compound fertilizer = (60-100 kg) + (6-8 kg) + (1-2 kg). Fertilization method: 1-1.5 meters away from the trunk, dig a hole, strip, or radial to a depth of 30-40 cm, and bury the fertilizer (biological bacterial fertilizer and compound fertilizer need to be applied separately). After the "Beginning of Winter", when entering the "March 9th" season, watering Zanthoxylum bungeanum with enough winter water is conducive to soil moisture preservation, which can keep warm and safe through the winter, increase nutrition, and improve the resistance of the Zanthoxylum bungeanum tree.
Pest control
In addition to overwintering on litter and weeds, some pathogens and eggs can also parasitic overwintering on tree branches and other places. Therefore, first, it is necessary to spray Solibal with "99" Insecticide before the pepper tree germinates, and spray the pesticide when the pepper leaves are not falling, which has excellent control effect. At the same time, spray pesticides on other trees around the pepper garden to prevent the spread of pests. The second is to combine pruning and clearing the garden in winter, spraying the pepper garden with insecticides such as enemy killer once, and then spraying with sulphur mixture and other bactericides the next day, which can kill insects, sterilize, mites, and eggs, which can effectively reduce The overwintering pests and diseases will reduce the pest damage in the coming year. The third is to use a hammering method to convection the glue area, knock it to the good skin, and then use a knife to scrape off the dry, cracked, and decayed glue scars, and apply a 20 times liquid of Lesben EC.
