Silicon is considered by the international soil community as the fourth plant nutrient element after nitrogen, phosphorus and potassium. Silicon fertilizer is a soluble mineral fertilizer containing calcium acid. It is non-toxic, odorless, non-corrosive and not easy to lose. It is widely used in rice, wheat, corn, cotton, peanut, rape, sugar cane, fruits and vegetables.
Most of the silicon needed for crops is provided by the soil, but there is very little silicon that can be absorbed by plants in the soil. Especially with the rapid development of agriculture, crops continuously absorb silicon in the soil, resulting in a gradual reduction of available silicon in the soil. According to surveys by relevant departments, 70% of the soil in the Yangtze River Basin in China is deficient in silicon, and about half of the soil in the Yellow River, Huaihai and East Peninsula is deficient in silicon, and the area lacking silicon is gradually expanding.
Improve quality and increase production. Silicon is an important nutrient element needed for crop growth. After absorbing silicon, crops can promote root growth and development, improve resistance to lodging, resistance to diseases and insects, drought, cold and nutrient absorption, and improve crop quality. The requirements for the development of “green foodâ€.
The demand for large prospects is good At present, China's lack of silicon arable land area of ​​about 50%, if the country promotes the application of silicon fertilizer, according to the annual application of 50 kg, the annual need for silicon fertilizer 30 million - 40 million tons, showing that China's silicon fertilizer market has great potential. Therefore, the promotion of the production and application of silicon fertilizer has very obvious social and economic benefits.

Complex Bearings
ERUNBEARING complex bearing is comprised of a Needle Roller Bearing of supporting radial load and a thrust bearing for supporting axial load which are assembled integrally. Comparing with individual use of a radial bearing and a thrust bearing for the same purpose, this complex bearing saves the required installation space and thereby can contribute to making the overall construction of an equipment more compact.
