To develop pollution-free vegetables, we must focus on the selection and improvement of production bases, the harmlessness of the planting process, and the “three levels†of the detection of residual vegetable poisons. We must pay attention to the production environment, species selection, cultivation of strong seedlings, fitness cultivation, and pest control. Quality testing "six links." In general, it is to take technical measures for the production of pollution-free vegetables, so that the base environment, production process and product quality can meet pollution-free standards. As site conditions for the production of pollution-free vegetable plots: It should be a pollution-free pollution source area that is three kilometers away from factories and hospitals. Planting plots should be convenient for irrigation and drainage, and the irrigation water quality should meet the national requirements. The soil on which the plots are planted should be deep and fertile, with good structure and organic matter content of 2%-5%. The area of ​​the site has a certain scale, and the land contiguously facilitates rotation and transportation is convenient. Improve vegetable production conditions The improvement of vegetable production conditions includes three aspects. The first is to improve field water conservancy facilities and improve drainage and irrigation systems. The second is to improve soil physical and chemical properties, so that the soil has a granule structure. The third is to improve the network of field roads and facilitate mechanized operations. To establish a cropland rotation system, different vegetable plots and different vegetable varieties adopt different rotation systems. Use agricultural facilities to improve ecological conditions and promote cross-species intercropping. Sound cultivation management measures Promote "fitness" cultivation, improve plant resistance and pest resistance. Use good seeds and disinfect seeds. The appropriate sowing, nurturing strong seedlings.
