There are different standards and requirements for the production of pollution-free agricultural products, green foods and organic foods.
First, the production of organic food
1. Origin of the environment: No chemical synthetic substances have been used in the first three years of the production, and there is no pollution, that is, the soil has a conversion period of three years.
2. It is not allowed to use any chemically synthesized pesticides, fertilizers, hormones, etc. during the production process.
3. In the production process, it is allowed to use organic fertilizer, biological bacterial fertilizer, plant source, biological source pesticide and mineral source pesticide sulfur and copper preparation.
4. It is not allowed to use any chemically synthesized food preservatives, additives, pigments, etc. during processing.
Second, the production of green food, pollution-free agricultural products
1. Origin environment
To produce green food and pollution-free agricultural products, we must first carry out environmental testing of the atmosphere, soil, water, etc. in the place of production, and the production indicators are qualified before production.
2. Fertilizer use technology
According to soil fertility and crop needs, determine the type of fertilization and the amount of fertilizer applied, and promote formula fertilization. Fertilization is mainly based on organic fertilizer, supplemented by chemical fertilizer. Commercial fertilizers must pass the registration and certification of the relevant state departments and production licenses, and the quality indicators meet the relevant national standards. The use of chemically synthetic fertilizer products that are not approved for registration is prohibited, ensuring that the fertilizers used do not adversely affect crops and the agricultural environment.
(1) Promote the use of organic fertilizers, commercial organic fertilizers, and microbial fertilizers. Under the premise of prohibiting the use of chlorine-containing compound fertilizers and nitrate-nitrogen fertilizers, chemical fertilizers are allowed to be used according to the following two principles.
1 Fertilizer must be applied in combination with organic fertilizer. The amount of pure nitrogen applied by fertilizer should not exceed the amount of pure nitrogen in organic fertilizer.
2 Fertilizer can also be combined with organic fertilizer and compound microbial fertilizer. The formula is 1000 kg of manure, 10 kg of urea or 20 kg of diammonium phosphate, and 60 kg of compound microbial fertilizer. The last top dressing must be carried out 30 days before harvest.
(2) It is forbidden to use municipal solid waste and industrial waste that have not been harmlessly treated.
(3) In principle, the farmyard fertilizer should be used locally, and the farmer's fertilizer should be confirmed to meet the requirements before use. No matter what kind of raw materials are used to make compost, farmyard fertilizer must be fermented at high temperature to kill parasite eggs, pathogens and weed seeds to achieve harmless hygiene standards. For high temperature composting, the composting temperature is required to be up to 50-55 °C for 5-7 days; for biogas fermented fertilizer, the sealed storage period is required to be more than 30 days; the high temperature biogas fermentation temperature is 53±2 °C for 2 days; parasite egg sedimentation above 95.
3. Pesticide use technology
We will implement the principle of “prevention first, comprehensive prevention and control†and adopt non-chemical control methods such as agriculture, physics and biology to minimize the use and use of pesticides.
(1) Agronomic measures and physical control, such as selection of disease-resistant varieties, rational rotation, improvement of agricultural ecological environment, strengthening of cultivation management, and scientific cultivation mode. Protect and utilize natural enemies and give full play to the natural control of natural enemies.
(2) Promote the use of biological source pesticides such as agricultural streptomycin, neutrophin, wuyimycin, chunleimycin, jinggangmycin, agricultural anti-120, etc.; mineral-derived pesticides such as stone sulfur mixture, Bordeaux mixture.
(3) Selective use of high-efficiency, low-toxic, low-residue pesticides. Commonly used insecticides include BT series, Averm series, chlorfenapyrs, plant extracts, and insect hormones (rice, card, gram, Affordable), a small number of organophosphorus pesticides (phoxim, dimethoate, trichlorfon, lesben, agricultural music) and other pesticides such as insecticidal bismuth, imidacloprid; fungicides are carbendazim, thiophanate, gram Dew, can be killed, acetochlor, etc. These pesticides are only allowed to be used once in a green season in green food production. In the production of pollution-free agricultural products, a growth period can be used 3 to 4 times.
(4) It is strictly forbidden to use highly toxic, highly toxic, high-residue pesticides and teratogenic, carcinogenic and mutagenic pesticides. Such as insecticides: methamidophos, phorate (3911), carbofuran (carbofuran), omethoate, monocrotophos, acesulfame, trisulfide, arsenic, hexachlorocyclohexane, DDT, 1605 , 1059, cyanide, chlordane, chlorpyrifos, insecticidal bismuth, aluminum phosphide, zinc phosphide, methomyl drug, dicofol, fluoroacetamide, etc. The fungicides include: chloropicrin, celidine, sodium pentachlorophenol, isopropyl phosphate, celecoxime, ulcer, 401 (antibiotic), dibromochloropropane, and organic mercury.
(5) Strictly implement the pesticide safety interval (that is, the time of the last application of the pesticide from the harvest). Generally, the bio-agriculture is about 3 to 5 days, the pyrethroid pesticide is 5 to 7 days, and the organophosphorus pesticide is 7 to 70 days (a few 14 days or more). The fungicides chlorothalonil and carbendazim require more than 14 days, and the rest are 7 to 10 days.
(6) Correctly diagnose pests and diseases, select the correct pesticides and strictly control the scope and dosage.
(7) Strengthen the forecasting of pests and diseases, and master the timely use of prevention and treatment indicators.
(8) Rational mixing and rotation of drugs to overcome the emergence and development of pest and disease resistance.
(9) After washing the equipment, properly dispose of the sewage, medicine bottles and medicine bags, and keep the remaining medicines in a safe place.
Safe agricultural product fertilizer technology
Safe agricultural products mainly refer to pollution-free agricultural products, green foods and organic foods.
