Wheat planting with sufficient fertilizer, mainly organic fertilizer and phosphorus, potassium fertilizer, is essential for the harvest of wheat. It is recommended to use compound fertilizers with medium nitrogen, high phosphorus and low potassium, because this is determined according to the physiological needs of wheat growth. In the early stage, there were more phosphate fertilizers and less nitrogen and potassium, so the fertilizer with high phosphorus applied to the base fertilizer was used in the jointing of wheat. After the application of nitrogen fertilizer and potassium fertilizer, the effect is better. Dryland wheat is mainly based on base fertilizer, and it is appropriate to apply 35%-45% of special fertilizer or 40-50kg of BB fertilizer. N, P, K formulas 18-24, 12-15, 5-7 are good. In the irrigation area, 45%-50% of the special fertilizer is applied to the wheat. Winter wheat base fertilizer is characterized by high phosphorus and low potassium, and advocates the application of organic fertilizer. Therefore, general-purpose compound fertilizer should be used for general fertility soil, and low-nitrogen and high-phosphorus compound fertilizer should be used for higher fertility soil.
