Pollution-free vegetable planting technology


To develop pollution-free vegetables, we must focus on the selection and improvement of production bases, the harmlessness of the planting process, and the detection of residues of poisons in vegetables. We must focus on the environment, variety selection, cultivation of strong seedlings, fitness cultivation, pest control, Quality testing "six major links." In general, it adopts technical measures for the production of pollution-free vegetables, so that the base environment, production process and product quality meet the requirements of pollution-free standards.
As a site for the production of pollution-free vegetable plots: it should be a pollution-free source area three kilometers away from factories and hospitals. The planting plots should be well drained and irrigation, and the irrigation water quality meets the requirements of the state. The soil in which the plot is planted should be deep and fertile, with good structure and organic matter content of 2% to 5%. The area of ​​the base has a certain scale, and the land is contiguous for easy rotation and convenient transportation.
There are three aspects to improving the conditions for the production of vegetables. One is to improve the water conservancy facilities in the field and to improve the irrigation and drainage system. The second is to improve the physical and chemical properties of the soil, so that the soil has a pellet structure. The third is to improve the field road network to facilitate mechanized operations. It is necessary to establish a farm rotation system to adopt different rotation systems for different vegetable fields and different vegetable varieties. Use agricultural facilities to improve ecological conditions and promote intercropping of different vegetables.
