At present, a variety of fertilizers, water-soluble fertilizers that have nutrients needed for crop growth, can be quickly dissolved in water, and are more easily absorbed by crops, are increasingly becoming the preferred fertilizers for farmers, and their application scope is gradually shifting from cash crops 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 fertilization method that dissolves solid fast-acting fertilizers in water and fertilizes them with water. 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 the nutrient utilization rate is improved. 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 nitrogenous fertilizers on surface volatilization, saving both nitrogen fertilizer and environmental protection, 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 to conventional fertilization, and can achieve good targets for both 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 caused by excess nutrients are reduced. The fertilization is simple, the fertilizer supply is timely, and the crops are easily absorbed. , improve fertilizer utilization and Other advantages.

Compression Spring is a kind of spiral spring,which bears inward pressure. The section of raw material usually is circle,and sometimes is
rectangle. The compression springs have the equal pitch. The compression springs have many shapes,such as cylinder,cone,convex,concave and non-circular and so on. The compression springs have a certain gap between coils. When the spring bears the load,it can contract distortion and store energy.
