Last Updated: 2024/11/22, What method of nitrogen, phosphorus and potassium fertilizer can improve the fertilizer efficiency of nitrogen, phosphorus and potassium fertilizer? Please introduce the following methods to improve the fertilizer efficiency of nitrogen, phosphorus and potassium fertilizer: 1. The main nitrogen fertilizers commonly used in nitrogen fertilizer agricultural production are ammonium sulfate, ammonium chloride, ammonium bicarbonate, ammonia, liquid ammonia, ammonium nitrate, calcium ammonium nitrate, urea and so on. Research.

Now how to use flushing fertilization is convenient and time-saving and labor-saving, can you use flushing fertilization instead of compound fertilizer? Flushing fertilization is also called water flushing fertilizer, that is, the solid quick-acting chemical fertilizer is dissolved in water and fertilized with water. From the point of view of fertilizer use, crops mainly rely on the root system to absorb nutrients, and the root hair area about 1 cm from the root tip is the most active area for nutrient absorption. Therefore, rush fertilization is most in line with the principle of scientific fertilization, nutrients can be absorbed by crops through mass flow and diffusion, but also can prevent the burning of seedlings caused by dry fertilizer. From the point of view of the way of fertilization, impulse fertilization not only fertilizes the crops, but also irrigates the crops, which is actually the application of the technology of integration of water and fertilizer. So, with the development and popularization of fertilization technology, can flushing fertilization completely replace compound fertilizer? According to the introduction of relevant experts, the traditional compound fertilizer is generally used as base fertilizer, and the dosage is large. In this way, the early stage of crops may cause excess nutrients, while in the later stage, there will be insufficient nutrients, which is not conducive to crop growth, so this way of fertilization is actually unscientific. Although a small amount of topdressing is the best way to replenish nutrients to crops, the main problem at present is that the labor cost is too high, cash crops or greenhouse can be used, but field cultivation is not practical. The development of drip fertilization technology can make this way possible, and some people even say that if sufficient topdressing can be ensured, it is not necessary to apply base fertilizer to crops, and the manufacturing process of flushing fertilization is cheaper than that of compound fertilizer. At present, flushing fertilization is widely used in greenhouse and open field vegetables, mainly in the prosperous period of vegetable growth, such as the full fruit period of fruits and vegetables, the heart period of Chinese cabbage after each picking, etc., with quick effect and good effect. However, with the development of slow and controlled release fertilizer technology, the utilization rate of compound fertilizer has been greatly improved, and nutrients can be evenly released throughout the crop growing period. Although it can not be said that flushing fertilization can completely replace compound fertilizer, flushing fertilization products are gradually becoming a hot word in the mouth of dealers and farmers, and a large number of domestic enterprises are gradually establishing their own brands. Flushing fertilization will enter a new stage of development. Get more water-soluble fertilizer application technology
