First, vigorously promote new high-efficiency fertilizers (1) Coated urea coating Urea is coated on the surface of ordinary urea with a colloidal film composed of trace elements such as boron, zinc, iron, manganese and molybdenum. Compared with ordinary urea, it has excellent performances such as slowness, long-term efficiency and high efficiency.
(II) Long-acting ammonium bicarbonate Long-acting ammonium bicarbonate has the advantages of stable nature, long fertilizer effect period and low volatilization loss. According to the multi-point test, the same amount of long-acting ammonium bicarbonate can increase the yield by 8.9%-24.7% compared with common ammonium bicarbonate, and the nitrogen utilization rate increases by 8.3%-25.1%.
Second, the application of chemical fertilizers and organic fertilizers combined with the emphasis on the use of chemical fertilizers and organic fertilizers: (1) organic fertilizers can improve soil structure and increase soil yielding potential; (2) organic fertilizers contain a variety of nutrients required for crop growth and development In particular, potassium and micro-enzymes in organic fertilizers can play a significant role in coordinating the supply of crop nutrients.
III. Coordinating the balanced fertilization of nitrogen and phosphorus fertilizers According to the soil test results and the fertilizer requirements of different crops, the proportion and amount of nitrogen and phosphorus fertilizers should be determined, the nutrients of crops should be balanced, and the current situation of partial nitrogen fertilizers should be changed.
Fourth, improve the fertilization method The first is to promote the use of ammonium bicarbonate as a base fertilizer. In this way, the utilization rate can be increased by 20% compared with the application, and 1kg of ammonium bicarbonate can increase the grain by 1.50kg. In addition, the deep application of ammonium sulphate to the ammonia smell can also kill underground pests. The second is to popularize the application of common Phosphate fertilizers or to mix them with organic plants. According to the survey: the application of common phosphate fertilizers or ditching can increase the yield by 10%. Utilization increased by 10%. The production of organic acids by ordinary phosphorus and organic fertilizer can promote the inefficient dissolution of phosphorus and the fixed phosphorus in the soil, and increase the effective phosphorus content. Ordinary phosphate fertilizer and organic fertilizer stacking as base fertilizer, phosphorus fertilizer efficiency can be increased by 30% -40%. The effect of equal amount of phosphate fertilizer on yield increase is 30% higher than that of non-stacked wheat, and 1.6kg for 1kg phosphate fertilizer.
V. Potassium Fertilizer and Micro-fertilizer Application According to Local Conditions In view of the current decline in soil potassium content, the application of potash fertilizer in potassium-deficient soils and high-yield plots and on potassium-sensitive crops can promote crop yields.
Micro-fertilizer has the characteristics of less dosage, less investment, and higher profit. It can be used according to the lack of local trace elements and the sensitivity of crops to micro-fertilizer.
(II) Long-acting ammonium bicarbonate Long-acting ammonium bicarbonate has the advantages of stable nature, long fertilizer effect period and low volatilization loss. According to the multi-point test, the same amount of long-acting ammonium bicarbonate can increase the yield by 8.9%-24.7% compared with common ammonium bicarbonate, and the nitrogen utilization rate increases by 8.3%-25.1%.
