How to apply compound fertilizer reasonably? Please introduce the application method of compound fertilizer with comprehensive nutrients, high content and good physical shape, but in the process of application, we should pay attention to three problems: first, because the soil chooses the variety of compound fertilizer because of crops, only in this way can its fertilizer effect be brought into full play. Cereal crops such as rice, wheat and corn (2348, 3.00 and 0.13%) need more nitrogen fertilizer and can choose nitrogen and phosphorus compound fertilizer. Legume crops can fix free nitrogen in the air and choose phosphorus and potassium compound fertilizer. Some cash crops can choose ternary or multi-component compound fertilizers adapted to local soil and climatic conditions. Second, compound fertilizer should be combined with elemental fertilizer. The nutritional composition of compound fertilizer is fixed, and only when combined with various elemental fertilizers can the nutrient needs of crops in different periods be met. Generally speaking, the compound fertilizer is suitable to be used as base fertilizer, while the elemental fertilizer can be used as topdressing in the peak and critical periods of crop fertilizer needs. Third, it should be done in a proper way. In all kinds of compound fertilizers, the proportion and form of various nutrients are different, coupled with different types of soil and crops, fertilization methods should not be the same, should be treated differently. Clayey soil with strong fertility should be applied deeply, while sandy soil is easy to be de-fertilized and can be applied many times in small amounts. The compound fertilizer containing ammonium nitrogen should be deeply applied to cover the soil to reduce the loss, and the compound fertilizer containing phosphorus and potassium nutrients should be concentrated and applied near the root system, which not only avoids the fixation of nutrients, but also facilitates the absorption and utilization of crops; for expensive potassium dihydrogen phosphate, generally, it should not be used as base fertilizer, but should be used as external forced fertilizer or seed soaking.
