I. Selection of pollution-free vegetable production bases
1. The base should be selected within 2 km of the surrounding areas where there is no pollution source, atmosphere, agricultural irrigation water, soil, etc. that should meet relevant standards.
2. The base should choose the main producing areas, high-yielding areas and unique ecological areas of vegetables as much as possible.
II. Healthy cultivation techniques for the production of pollution-free vegetables
1, pay attention to crop rotation, avoid heavy crops, reduce soil-borne diseases.
2. Increase plant resistance through grafting techniques.
3. Implement high-ridge cultivation techniques to give the crop a good growing environment.
4, the use of membrane irrigation, less high humidity disease.
5, use fine varieties. According to the local disease occurrence law, select the appropriate disease-resistant varieties.
6, do a good job of seed treatment, reduce the seeds with bacteria, and cultivate non-toxic strong seedlings.
7. Strengthen seedling management and increase plant resistance.
Third, fertilizer-free technology for the production of pollution-free vegetables
1, scientific fertilization. In the fertilization category, organic fertilizers should be the main supplement, supplemented by other fertilizers. In the fertilization method, basal fertilizer should be the main supplement to topdressing. In the composition of fertilizers, multiple compound fertilizers should be the mainstay, supplemented by compound compound fertilizers.
2. It is forbidden to use organic fertilizers that have not been detoxified and those that fail to pass the registration and certification of the relevant state departments.
Fourth, pollution-free vegetable production and pest control technology
Implementing the plant protection policy of “prevention-oriented, comprehensive prevention and control†adopts a variety of effective non-chemical control methods such as agriculture, physics, biology, and ecology to reduce the number and amount of pesticides used.
Fifth, pollution-free vegetable production processing technology
The pollution-free vegetable production must be harvested timely, cleanly, neatly, and packed according to categories to prevent extrusion damage and keep it fresh and beautiful. Within 50 meters around the pollution-free vegetable processing area, there should be no pollution source, and no pollution should be performed during the processing operations.
VI. Quality Testing Techniques for Harmless Vegetable Production Agricultural products produced by pollution-free vegetable production bases must meet the criteria for the production of pollution-free agricultural products. Only after inspections by relevant monitoring units and approval by the corresponding regulatory agencies can the pollution-free agricultural product logo be used.
