In recent years, the types and number of pests and diseases that affect jujube trees have shown an upward trend, and it is necessary to carry out chemical control during the growing season. However, the large investment in chemical prevention and control, as well as the expense and labor, are also liable to cause pesticide residues, and they are also contrary to the requirements for the production of green fruits. According to the overwintering characteristics of jujube pests and diseases, combined with winter management, targeted prevention and treatment can have a multiplier effect. I. Qingyuan Jujube rust, green-lipped stink bugs, and date moths and other pests are overwintering in the litters or weeds under the trees. Therefore, jujube trees should be cleaned in time after the fallen leaves, and the dead branches, rotten fruit, and Weeds are cleaned up and burned or buried underground. Second, dig worms, insects 茧 桃 桃 食 食 桃 桃 桃 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧. , can effectively reduce the base number of insects in the coming year. Third, the temperature of the old skin under the bark is 1-3°C higher than the temperature. Bark and tree gaps are wintering sites for pests and diseases such as Ziziphus jujube and Red spider. By scraping the old skin, you can not only eliminate pests but also stimulate tree growth. The scrapings are carried out after defoliation and before germination. When scraping the skin, lay a plastic sheet under the tree to collect the bark and insects, and then burn or deep. Fourth, white painted white trunk, both cold and pest control pest control. The formulation of whitening agent is 12 parts of quicklime (open with cold water), 2 parts of sulfur or 3 parts of lime sulfur stock solution, 2 parts of salt (opened with hot water), 36 parts of water, and proper amount of glue. Lime and sulfur can prevent freezing, prevent sunburn, and prevent disease and kill insects. Salt helps lime penetrate the bark to keep moisture and prevent lime cracking and peeling. Adding glue can enhance the adhesion of the whitening agent. The white part of the painting should be high. All the branches that scrape off the old skin should be painted white to prevent dry tips. 5. The old trees in Mushudong are prone to breeding pests and diseases, and are also used as wintering sites for pests such as juvenile armyworm. In winter, 10 parts of clay can be used and 3 pieces of broken wheat straw can be added. Adding a little insecticide, water and slurry can plug the tree holes. Live to kill overwhelming insects. Sixth, cutting worms, worms combined with pruning in winter, cut off the larvae damaged by the turtle larvae. For severely damaging branchlets, the overwintering insects on them can be removed with a wire brush, and the overwintering bugs of the yellow thorn moth must be carefully removed. VII. Spraying chemicals Because of the waxy shell on the surface of turtle wax, it is difficult for general chemical pesticides to kill it and can be sprayed with diesel emulsion to eliminate it. Before the jujube sprouts, the entire tree should be sprayed evenly and thoroughly with Baume 5 degree lime sulfur, which can control the red spider, pear orchard and other pests.
