What are the requirements for green onions for pesticides?

Green onions are common vegetables in life and are vegetables that most people like to eat. In the process of planting green onions, some pesticides will inevitably be used. This article will give you a detailed introduction to the requirements of green onions for pesticides.

In the cultivation of green food crops, the following principles are adhered to: the use of agronomic, physical, and biological control measures can basically achieve the purpose of prevention and treatment, and can be used without drugs; when it is necessary, high-efficiency, low-toxic, low-residue pesticides should be preferred; The time, concentration and method of applying pesticides to meet the principle of optimal control effect and minimum residue; it is necessary to prohibit the use of highly toxic, high-residue or carcinogenic, teratogenic and mutagenic pesticides such as methamidophos and omethoate. Carbofuran, carbofuran, trithiophos. Zinc phosphide, etc. Strict implementation of safe use standards and reasonable use of pesticides is a key link to ensure the health of agricultural products. For pesticides that are allowed to be used in limited quantities, the amount of drugs used should be minimized. Each pesticide can only be used once. The last dose was administered to ensure administration 40 days before harvest.

Q: What are the fertilizer requirements for the production of green food green onions?

Green food is divided into AA grade and A grade. 2 technical grades AA grade green food can not use other chemical synthetic fertilizers, fully in line with international standards. Part A green food production allows a limited amount of chemical synthetic fertilizer to be used, but the use of nitrate nitrogen fertilizer is still prohibited. If other fertilizers must be used in production, the specific methods and dosages of various fertilizers should be used to ensure that no product pollution is caused, so as to avoid adverse consequences on the environment and crops, according to the “Green Food Fertilizers” developed by China Green Food Center. Guidelines apply. Fertilizer must be applied in combination with organic fertilizers. The amount of organic fertilizer must reach the level of maintaining or increasing soil organic matter content. The ratio of organic nitrogen to inorganic nitrogen is not more than 1:1. For example, 1000 kg of high-quality glutinous fertilizer, 10 kg of urea, and manure are used as base fertilizer, and urea can be used as base fertilizer and top dressing. The producer should increase the application of organic fertilizer and phosphate fertilizer. The onion is applied for 20kg of ternary compound fertilizer per 667m at the beginning of growth. The fertilizer is applied to the ditch back, mixed and ploughed, smashed in the ditch, and then watered. The growth period of scallions is the fastest period of production formation, and 20kg of ternary compound fertilizer is applied every 6672m. The soil fertility will be improved year by year, and the production level will be continuously improved to achieve the goal of sustainable development. For example, if the high-quality farmyard manure is 60t/hm, the seedbed is applied with diammonium phosphate 100g/hm and potassium sulfate 25g/hm.
