3.1 Production environment
3.1.1 The cattle production area should meet the requirements of NY/T391 and NY/T855. Choose an agricultural production area that is not directly or indirectly polluted by industrial "three wastes".
3.1.2 The production area should be far away from major transportation routes such as roads, stations, and airports to avoid pollution from air, soil, and irrigation water. 3.1.3 There should be no pollution sources that pose a threat to the production environment in the upwind direction of the production area and the upstream of the irrigation water source. The atmosphere should meet the requirements of (I39137, and the irrigation water should meet the requirements of (GB5084). 3.1.4 The cadmium content of peanut products should meet the requirements of NY/T420. 3.2 Earth dam conditions
3.2.1 Eggplant should be planted in ten soils with rich organic matter, good structure, sufficient nutrients, strong water and fertilizer retention, and good ventilation. 3.2.2 The soil environment should meet the second-class secondary standard in (GI315618 standard, and the water quality should meet the requirements of (GB5084. 3.2.3 Dragon's birthday should meet the requirements of NY/T8 55 requirements, the land is leveled, the thickness of the upper layer is 50cm, the thickness of the tillage layer is 20cm, the content of organic matter in the soil is>0.+%, the available nitrogen>70mg/kg, the available phosphorus>8mg/kg, the available potassium>67mg/kg, and the content of organic matter in the tillage layer is ≤0.25mg/kg3.2.4: The soil detection method shall be implemented in accordance with the provisions of CB/T17141, NY/T889, NY/T1121.6 and NY/T1121.7. 3.3 Soil improvement
Choose a plot with a thicker ten-layer. After the autumn crops are harvested, the autumn plowing or winter turning is 20cm30cm. After plowing, harrow the land to ensure harvesting. In winter, the sticky upper soil is improved by pressing 150m*-225tn of sand per hectare. For plots with high cadmium background values, according to the soil environmental conditions, adopt the application of additional organic fertilizers, calcium fertilizers, planting high-enrichment saw plants, and turning over the surface and bottom to reduce cadmium pollution.

4 FertilizationbzxZ.net
4.1 Fertilizer selection
The selection of fertilizers should meet the requirements of G3/T23349. 4.2 Rational application of chemical fertilizers
Implement the above formula fertilization and apply chemical fertilizers rationally. Avoid excessive application of fertilizers, reduce the accumulation effect of fertilizers in the soil, and effectively control the total amount of cadmium. The application of KCI should be reduced, and fertilizers containing KCI should be replaced with fertilizers containing K2SO4. The amount of phosphorus fertilizer is 30kg~50kg per 667m3, and the fertilizer should be turned into the tillage layer before sowing. Increase the application of calcium fertilizer to reduce the absorption of calcium by peanuts. 4.3 Increase the application of organic fertilizers
It is recommended to apply organic fertilizers, which can fix cadmium in the soil and reduce the absorption of cadmium by peanuts. 2
