“The predatory mite is the natural enemies of red spiders and it is a very safe and effective way to prevent and treat strawberry red spider mites.†On February 12th, Zhao Huiyan, a professor at the Plant Protection College of Northwest Agriculture and Forestry University, and his entourage walked in. The purpose of this trip is to send predatory mites for strawberry spider mites to the park in the town of Weixin Town, Meixi County, Baoji City, Shaanxi Province. “After the discovery of the red spiders last year, because the park was not controlled in a timely manner, it led to the proliferation of red spiders, seriously affecting the yield and quality of strawberries. So this year we found that the red spiders are very important. The temperature gradually increased during this time. Control can easily lead to the outbreak of pests." Zhao Huiyan said. The reporter has learned that the Yuxiang Modern Agricultural Park has more than 6,000 mu of strawberry planted. It is now the national standard demonstration area for high-quality strawberry production, the production base for pollution-free agricultural products in Shaanxi Province, and the agricultural industrial science and technology park in Baoji City. The park is centered on Daixi Village and is driven by radiation. Multiple villages. Strawberry has also become a major industry for the local people to increase their income. Zhao Huiyan introduced to reporters that strawberry red spider (also called leafhopper - aphid on leaves) is an important insect pest that harms strawberries. Its individual is 0.1-0.5 mm in size, and its reproduction speed is very fast. Generation is about 20 days. It sucks plant sap with sucking and sucking mouthparts, destroys leaf tissue and chlorophyll, slows leaf development, and shrinks when leaves protrude. When the damage is serious, the leaves are rust-colored and inhibit the growth of the plants, which has a serious impact on the yield and quality of the strawberries. “In the past, the method of preventing and controlling spider mites was the use of chemical pesticides, which led to a series of problems,†said Zhao Huiyan. She told reporters that at present, they are using a method of ecological regulation, that is, using a variety of natural or artificial methods to regulate the population of pests, one of the key technologies is the method of biological control, that is, “treating the disease with fleasâ€, Use natural predators of red spider - predator to adjust the amount of pests. Then, what are the advantages of "treating defects with 螨"? Zhao Huiyan told reporters that taking this approach has four advantages. First, to reduce the use of chemical pesticides by 60%; second, to maximize the use of natural control forces to reduce pest resistance; third, to reduce pesticide residues and reduce environmental pollution; fourth, good specificity, predation, predation, predation Red spider, whitefly (another pest). It is understood that a predator can prey on 300-500 red spiders at the same time, but also sucking insects eggs, has a very significant effect on the control of spider mite damage. A seedbed or seedling bed is the local soil environment in which seeds are planted. Often it comprises not only the soil but also a specially prepared cold frame, hotbed or raised bed used to grow the seedlings in a controlled environment into larger young plants before transplanting them into a garden or field. A seedling bed is used to increase the number of seeds that germinate.
