How to use pollution-free vegetables

At present, pollution-free production is an important part of standardized vegetable production. The technology for producing pollution-free vegetables is as follows:
The so-called pollution-free vegetables are vegetable products that meet the national or agricultural industry's pollution-free food mark. The main concern in the production process is the application of pesticides and fertilizers. The problem of pesticides and fertilizers is solved to solve the technical problems of pollution-free production.
At present, in the production of pollution-free vegetables, mainly the use of pesticides, pesticides are mainly pesticides. In terms of medication, vegetable farmers generally have a one-sided error habit. Even in the absence of pests, some giant poisons are used. Highly toxic and high residual pesticides are used for prevention and treatment.
1. Rational use of pesticide technology for pollution-free vegetables.
1, to prevent prevention, comprehensive prevention. Priority is given to agricultural measures, physical measures, biological measures, and scientific use of high-efficiency, low-toxic, low-residue pesticides. 1 agricultural measures. Choose resistant varieties, rotate for simmering, warm soup soaking, grafting technology, high temperature shacks, etc. 2 physical measures. Use black light, sweet and sour liquid, yellow plate trap, magnetized water irrigation, sonar technology, ozone and so on. 3 biological measures. Mainly use biological pesticides made from biological bacteria. Insecticides include BT biological pesticides (Bacillus thuringiensis) Liuyangmycin, rice bran and Ifotin preparations.
Antibiotic fungicides mainly include penicillin, streptomycin, neomycin, ciprofloxacin, kecocon, cultivar 120, and xylomycin. 4 scientific use of pesticides. The type of pesticide used, the banned pesticides, the safe dose of pesticides and the safety interval should be clarified.
2. Allow low-toxic and low-residue pesticides to be used in limited time. (See the 5th edition of the plant protection classroom in the next issue) 1 Strictly implement the rational use guidelines for pesticides. These regulations should be strictly enforced in the prevention and control of pests and diseases, and the dose (concentration) should not be increased arbitrarily and the number of applications should be increased and the safety interval should be shortened. 2 Choose to use a reasonable dosage form and application method. Anti-season deep winter cultivation, spraying liquid at low temperature may lead to slow growth of vegetables and aggravation of the disease. Therefore, dust and aerosol should be used as much as possible to reduce the humidity in the shed. The main dusts are gram, carbendazim and chlorothalonil; The aerosol mainly includes chlorothalonil, anti-virus sputum and the like. 3 alternate medication. Repeated use of the same agent will cause resistance to certain pests and diseases, and reduce the control effect. Vegetable farmers should choose different types of drugs and use them reasonably.
