Applying wheat base fertilizer is an important measure to improve soil fertility in wheat fields. The application method of winter wheat base fertilizer is proper, and the fertilizer effect can be maximized, so that the early seedlings of early winter can be divided into early roots, early roots, cultivated strong seedlings, and improve the cold resistance of wheat. After winter, the stems and leaves can grow rapidly and the young ears are completely differentiated. The ear formed in the unit area is larger and lays the foundation for the growth after spring. Alleviate the contradiction between water and nutrients in spring management, and strive for spring management initiative. At the same time, the base fertilizer also has a good effect on the medium-term stability of the wheat, the formation of panicles and prevention of early premature aging.
Base fertilizer application method: When the quantity is large, it should be applied in full layer. The coarse fertilizer can be applied deep before the cultivated land, and the fine fertilizer should be applied as a superficial layer fertilizer. When the amount of base fertilizer is small, it should be applied centrally, and the method of applying or applying the hole should be adopted.
Applying the base fertilizer not only means that the amount of fertilizer is sufficient, but more importantly, it refers to the reasonable ratio of nutrients and balanced fertilization, that is, formula fertilization. The principle of fertilization in high-yielding wheat fields is “stable nitrogen, phosphorus, potassium, and organic fertilizerâ€. The proportion of nitrogen fertilizer applied in the base fertilizer generally accounts for 30%-70% of the nitrogen application rate in the whole growth period, and the proportion of the base fertilizer in the high-fertility plot should be appropriately reduced. The proportion of the base fertilizer applied to the low-fertility plot should be appropriately increased. The principle of total nitrogen application during the whole growth period is generally determined according to the level of soil fertility. High-fertility plots generally apply 12-14 kg of pure nitrogen per mu; medium-fertility plots generally apply 13-15 kg of pure nitrogen per acre; low-fertility plots generally apply 14-16 kg of pure nitrogen per acre. Phosphorus and potassium fertilizers and micro-fertilizers are all used as base fertilizers. The application rate is generally 11 kg of phosphorus pentoxide per acre and about 10 kg of potassium oxide.
