At present, a multi-fertilizer that has the nutrients needed for crop growth, can be quickly dissolved in water, and is more easily absorbed by crops – water-soluble fertilizers are becoming the preferred fertilizer varieties for farmers, and their application range is gradually moving from cash crops to field crops. . Because water-soluble fertilizer has the characteristics of water saving, fertilizer saving, labor saving, and increased production, it fully meets the requirements of fertilizer for water-saving integration of water-saving agriculture, so the development prospect is very broad. It is understood that China's water-soluble fertilizer is currently in a critical period from the conversion of auxiliary fertilizers to major fertilizers.

The “water and fertilizer integration” technology is a new agricultural technology that integrates irrigation and fertilization. It is a fertilization method in which a solid quick-acting fertilizer is dissolved in water and fertilized with water. Generally, the fertilizer is dissolved and mixed in the pool in the field, and the water is used as a carrier to complete the fertilization while irrigating. The advantage of this technology is that fertigation fertilization has fast fertilizer efficiency and improved nutrient utilization rate, which can avoid the problem that the fertilizer is applied to the dry topsoil, which is easy to cause volatilization loss, slow dissolution, and finally the fertilizer effect is slow; especially the ammonium state and urea are avoided. The problem of nitrogen loss applied to the surface volatilization loss not only saves nitrogen fertilizer but also contributes to environmental protection, and has significant effects in water saving.

The “water and fertilizer integration” irrigation and fertilization system can save 50% to 70% of fertilizer compared with conventional fertilization, and achieve the goal of good crop yield and quality in production. The advantage of this technology is that fertigation fertilization has fast fertilizer efficiency, improved nutrient utilization rate, balanced fertilization and concentrated fertilization, reduced fertilizer volatilization and loss, and loss caused by excess nutrients. It has simple fertilization, timely fertilizer supply and easy absorption of crops. Improve the utilization of fertilizers and other advantages.
