China is a developing agricultural country. Agriculture is the foundation of the country. Developing agriculture well is a fundamental matter of our country. In order to produce high-yield agricultural products, it is the key to fertilize the fertilization work. Different fertilizers have different fertilization methods. The following is a brief introduction to the fertilization methods of several common fertilizers.
First, the fertilization method of phosphate fertilizer: Phosphate fertilizer moves in the soil, easy to be fixed. When making seed fertilizer, you can use 1-2 times of phosphate fertilizer 1-2 phosphate fertilizer to make the soil dry and evenly mixed. After sowing or planting after planting or planting for base energy and early topdressing, it can be applied before ploughing, or After ploughing, the ridge is applied (ie, layered). Layered application, deep application of phosphate fertilizer can meet the needs of crops in the middle and late stages, and shallow application can be absorbed by crops during seedling stage. Early application can be applied to soil layers with dense root coefficients.
Second, the fertilization method of potassium fertilizer: Potassium fertilizer should be combined with base fertilizer or base followers. When it is used as a base fertilizer, it can be applied to the bottom of the plow before the cultivation or arable land, and the pressure is used as the base fertilizer. Followers should be early, can be ditched or applied.
Third, the fertilization method of nitrogen fertilizer: deep application of nitrogen fertilizer can greatly reduce the loss of nitrogen fertilizer, and the effect of increasing yield is significantly increased by 10% to 30%, and the yield is increased by 10%-20%. When nitrogen fertilizer is used as the base fertilizer, it can be ploughed into the soil after ploughing or spreading, or ridged and applied. When doing topdressing, it can be applied to the ditch and the hole. The depth of fertilization is generally 6-10 cm. In the case where deep application is impossible, the application should be immediately applied with water.
Fourth, the fertilization method of micro-fertilizer: zinc fertilizer (zinc sulfate) based on the amount of 1-1.5 kg, soaking seeds with 0.03%-0.09% zinc sulphate solution for 12 hours, seed dressing with 4-6 grams of zinc sulfate per kg of seeds The spraying concentration is 0.2%-0.3%; the boron fertilizer (borax) base is applied 0.5-1 kg, the soaking is immersed in 0.01%-0.02% borax solution for 6-12 hours, and the seed dressing is sprayed with 0.5-1 g per kg. The concentration of 0.2%; iron fertilizer (ferrous sulfate) based on the amount of 2-3 kg of acre, soaking seeds with 0.05% ferrous sulfate solution for 12 hours, spraying concentration of 0.2% -0.3%; boron fertilizer (borax) based on acres The dosage is 0.5-1 kg, soaking seeds with 0.01%-0.02% borax solution for 6-12 hours, seed dressing 0.5-1 kg per kg of seeds, spraying 0.2% iron fertilizer (ferrous sulfate) base fertilizer application amount 2 3 kg, soaking seeds with 0.05% ferrous sulfate solution for 12 hours, spraying concentration of 0.3% -0.5%; manganese fertilizer (manganese sulfate) based on the amount of 2-3 kg, soaking seeds with 0.05% -0.1% manganese sulfate solution For 12 hours, 4-8 g of manganese sulfate per kg was applied, and the concentration was 0.1%.
Different fertilizers have different fertilization methods. If the correct fertilization method is used during the growth of crops, the agricultural production will increase and increase.
