| With the rapid development of fertilizer industry and the increasingly serious shortage of water and mineral resources in China, the new type of fertilizer, represented by water-soluble fertilizer, has attracted much attention. At the same time, the development of fertigation technology has promoted the research of water-soluble fertilizer. Applying water and fertilizer together and adjusting fertilizer with water can not only save water and fertilizer, improve the utilization rate of water and fertilizer, but also reduce labor input and improve production efficiency. Under the background that the state advocates the development of water-saving and fertilizer-saving agriculture, local governments at all levels respond to the national development strategy one after another, and more and more enterprises conform to the trend of the times and devote themselves to the water-soluble fertilizer industry. At present, the effective registration of water-soluble fertilizers is increasing year by year, and the new situation of water-soluble fertilizers in fertilizer industry has been gradually formed. However, due to the late start in water-soluble fertilizer industry, and there are some problems such as immature production technology, substandard production and imperfect fertilization methods. This paper reviews the development history of water-soluble fertilizer at home and abroad, and briefly describes its production technology and fertilization technology. The advantages and problems of water-soluble fertilizer and fertigation technology are summarized based on the research of its application in agriculture in China. Based on theoretical analysis and practical application, relevant development suggestions are put forward from various aspects, levels and perspectives. |
