Green strawberries are grown by "controlling mites with mites"

These days, the first batch of strawberries this winter is ripe, which is Zhao Zhenyu's busiest time.

"my strawberries really don't get a drop of pesticide." Zhao Zhenyu is a graduate student majoring in vegetables in the School of Agriculture, Inner Mongolia Agricultural University. he grows strawberries, which is different from others. There is a screen-like "curtain" at the door of the shed. It turns out that this "curtain" is an anti-insect net. Not only the doorway, but the whole shed is covered with an anti-insect net, just like a big mosquito net. With it, the insects outside the shed will not be able to get into the shed.

Entering the greenhouse, there are some 2-inch square bags hanging every few meters in the shed. "each small bag contains more than 200 predatory mites, which can be used to prey on two-spotted leaf mites and red spiders in strawberry fields, eliminating the need for chemical pesticides." Zhao Zhenyu said, "Don't underestimate these bugs that are smaller than sesame seeds. They are real biological guardians." Taking the greenhouse in Genbao Village, Jinhe Town, Saihan District, Hohhot as an example, the prevention and control rate of two major diseases and insect pests, such as strawberries and tomatoes, and red spiders, has reached 100%. " In addition, green prevention and control measures such as solar energy insecticidal lights, trapping boards and growing garlic between ridges are widely used here.

Needless to say, the benefits of green prevention and control. In recent years, people put forward higher and higher requirements for the health of eating, and the problem of excessive pesticide residues in agricultural products has attracted widespread attention. In some places, over-reliance on the use of chemical pesticides has led to the increase of drug resistance of diseases and pests, the decline of control effect, the aggravation of agricultural non-point source pollution and the destruction of biodiversity. Changing the traditional way of prevention and control, vigorously promoting green prevention and control technology, and controlling pesticide and pest toxin residues from the production process can be said to be an effective way to promote the quality and safety of agricultural products and ecological environment.

Saihan District is the capital's green pollution-free vegetable base. Vegetable cultivation has become the main way for farmers to get rich and increase their income. Green prevention and control technology is first promoted here. Zhao Zhenyu is a science and technology commissioner based in Genbao Village.

"I really didn't expect that we would be able to prevent diseases and insect pests without using pesticides the old way." From the initial skepticism to the present conviction, some villagers in Genbao Village began to change their ideas, gradually changing from passive acceptance to active application, from traditional pest control to biological pest control.

However, the promotion of green prevention and control technology is not easy. Farmers often believe that seeing is believing, and they will be convinced when they see crops sprinkled with pesticides and a large number of pests have died. However, the use of biological control can not achieve such an immediate effect. Every living creature in nature has one or more natural enemies. Through the use of natural enemies, green prevention and control technology can effectively restrain the mass reproduction of pests, achieve the balance between biological populations, and achieve the purpose of pest control.

"Pest control is not to kill all pests, but to keep pests from flooding. However, the green prevention and control technology has not formed a system at present, and not all diseases and insect pests can be prevented and controlled in time. Coupled with the high cost of prevention and control, it is a bit difficult for farmers to quickly accept such an idea. " Zhao Zhenyu has been promoting green strawberry prevention and control technology since he started growing strawberries in 2014.

Today, he has an entrepreneurial team of 8 people, each performing his own duties, and co-founded Inner Mongolia Chiqing Agriculture and Animal Husbandry Technology Co., Ltd. They put forward the plan of "red green quality products", that is, one product drives a village, using green prevention and control technology to make farmers really rich, so that more people can eat healthy agricultural and animal husbandry products.
