Can water-soluble flush fertilizer be used instead of compound fertilizer?
Nitrogen fertilizer, phosphate fertilizer, potassium fertilizer: what methods can improve the fertilizer efficiency of nitrogen, phosphorus and potassium? Please give an introduction. The following methods can be used to improve the fertilizer efficiency of nitrogen, phosphorus and potassium: 1. Nitrogen fertilizer. The nitrogen fertilizers commonly used in agricultural production mainly include ammonium sulfate, ammonium chloride, ammonium bicarbonate, ammonia water, liquid ammonia, ammonium nitrate, calcium ammonium nitrate, urea, etc. Resear...
Now that water-soluble flush fertilizer is so convenient, time-saving and labor-saving to use, can water-soluble flush fertilizer be used instead of compound fertilizer?Water-soluble flush fertilizer, also called water-flush fertilizer, is a fertilization method in which solid quick-acting chemical fertilizer is dissolved in water and applied with the water carrying the fertilizer. From the perspective of fertilizer use, crops absorb nutrients mainly through the root system, and the root hair zone about 1 cm from the root tip is the most active area for nutrient absorption. Therefore, water-soluble flush fertilizer best conforms to the principles of scientific fertilization; nutrients can be absorbed by crops through mass flow and diffusion, and it can also prevent seedling burn caused by dry broadcasting of fertilizer. From the perspective of the fertilization method, water-soluble flush fertilizer both fertilizes the crops and irrigates them, which is in fact the application of integrated water and fertilizer technology.
Then, with the development and promotion of fertilization technology, can water-soluble flush fertilizer completely replace compound fertilizer? According to relevant experts, traditional compound fertilizer is generally used as base fertilizer and in large amounts. As a result, crops may suffer from excessive nutrients in the early stage and insufficient nutrients in the later stage, which is not conducive to crop growth, so this fertilization method is actually unscientific. Although applying topdressing in small amounts many times is the best way to supplement nutrients to crops, the main problem at present is that labor costs are too high. It can be used for cash crops or greenhouses, but it is not very practical for field cultivation. The development of drip irrigation and fertilization technology can make this method possible, and some even say that if sufficient topdressing can be guaranteed, there is no need to apply base fertilizer to crops, and the manufacturing process of water-soluble flush fertilizer is simpler and lower in cost than that of compound fertilizer.
At present, water-soluble flush fertilizer is widely used on greenhouse and open-field vegetables, mainly during the vigorous growth period of vegetables, for example, the full fruit period of fruit vegetables, after each harvest of melons and fruits, the heading period of Chinese cabbage, etc., with quick results and good effects.
However, with the development of slow and controlled release fertilizer technology, the utilization rate of compound fertilizer has been greatly improved, and nutrients can also be released evenly throughout the entire crop growth period. Although it cannot yet be said that water-soluble flush fertilizer can completely replace compound fertilizer, water-soluble flush fertilizer products are gradually becoming a hot topic among distributors and farmers, and a large number of domestic water-soluble flush fertilizer enterprises are gradually establishing their own brands. Water-soluble flush fertilizer will enter a new stage of development.
