At present, a multi-fertilizer-water-soluble fertilizer that has the nutrients needed for crop growth, can be quickly dissolved in water, and is more easily absorbed by crops is becoming the preferred fertilizer type for farmers, and its scope of application is gradually moving from economic to field crops. Because the water-soluble fertilizer has the characteristics of water saving, fertilizer saving, labor saving, and production increase, it fully meets the requirements of water-saving agriculture “water and fertilizer integration†for fertilizer, so the development prospect is very broad. It is understood that at present, China's water-soluble fertilizer is in a critical period of transition from auxiliary fertilizer to main fertilizer.
"Water and fertilizer integration" technology is a new agricultural technology that integrates irrigation and fertilization. It is a method of fertilizing solid fast-acting fertilizers in water and using water as fertilizer. The fertilizer is generally dissolved and mixed in a pond in the field, and water is used as a carrier, and fertilization is completed at the same time as irrigation. The advantage of this technology is that the fertigation effect of irrigation and fertilization is fast and nutrient use efficiency is increased. This can avoid the volatilization loss, slow dissolution, and slower dissolution of fertilizers applied to the relatively dry topsoil; especially the ammonium and urea are avoided. The application of nitrogen fertilizers on the surface volatilizes, which saves both nitrogen fertilizer and environmental protection. It also has a significant effect on water saving.
The “water and fertilizer integration†irrigation and fertigation system can save 50% to 70% of the fertilizer compared with conventional fertilization, and can achieve the goal of good crop yield and quality in production. The advantages of this technology are that the fertigation effect of irrigation and fertilization is fast, the nutrient utilization rate is improved, balanced fertilization and concentrated fertilization are realized, the volatilization and loss of fertilizers and the loss of nutrient excess are reduced, and the fertilization is simple, the fertilizer supply is timely, and the crop is easily absorbed. , improve fertilizer utilization and other advantages.
