The development of pollution-free vegetables, the focus is on the selection and improvement of good production bases, the harmlessness of the planting process, the detection of three residues of vegetable residues, the selection of the environment, the selection of varieties, the cultivation of strong seedlings, fitness cultivation, pest control, quality Detect "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.
First of all, it is to choose the environmental conditions to ensure the basic requirements for the production of pollution-free vegetables.
1. 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.
2. The planting plot should be convenient for irrigation and drainage, and the irrigation water quality meets the requirements of the state.
3. The soil of the planting plot should be deep and fertile, with good structure and organic matter content of 2-5%.
4. The base area has a certain scale, and the land is contiguous for easy rotation and convenient transportation.
The second is to improve the ecological conditions in the field and create an environment conducive to the growth of vegetable crops.
1. Improving the production conditions of vegetables: Improving the production conditions of vegetables includes three aspects: First, improve the water conservancy facilities in the field and 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.
2, to establish a farmland rotation system
Different rotation systems are adopted for different vegetable fields and different vegetable varieties.
3. Use agricultural facilities to improve ecological conditions.
4. Clean the countryside and improve the ecological conditions.
5. Promote intercropping of different vegetables.
Third, improve cultivation management measures, promote “fitness†cultivation, and improve plant resistance and pest resistance.
The first is to choose good varieties.
The second is to carry out seed disinfection.
The third is to plant at the right time.
The fourth is to cultivate strong seedlings.
