One, full-layer fertilization basal fertilizer application method. According to the nature of the fertilizer used, the fertilizer is evenly distributed in the soil layer through tillage, and this method can be applied to crops that are spread, densely planted or have a large amount of fertilizer. Whole-layer fertilization can accelerate the maturing process of the soil, and the crop can continuously obtain nutrients during the whole growth period, and can make the crop roots extend downward.
Second, layered fertilization A method of applying basal fertilizer. In combination with deep plowing and deep plowing, a large amount of delayed-effect fertilizers are applied to the soil surface, so that nutrients in the soil in each layer are evenly distributed.
III. Fertilization by Stage Fertilization The fertilization method for supplying nutrients during the growth and development of plants. There are basal fertilizers, seed fertilizers, and topdressing fertilizers for specific applications. Fertilizers can be divided into several periods according to growth and development stages to make fertilizers. Such as the return of green wheat winter fertilizer and panicle fertilizer. Fertilization in stages can reduce fertilizer loss.
When nutrients are applied at the time of greatest need, they are better absorbed by crops while controlling plant growth and development. This is a common method of fertilization.
