A few days ago, it was learned from the seminar on the development of new chemical fertilizers held by China Nitrogen Fertilizer Industry Association that new breakthroughs have been made in the coating materials for domestic controlled-release fertilizers. Sulfur-coated urea is combined with bio-carbon energy technology to produce new carbon-sulphur-coated urea, which can effectively reduce the loss, leaching and volatilization of fertilizers, save 30% to 40% of fertilizer, and simultaneously increase the urea content in rice. The utilization rate has increased from about 30% to 50% to 60%.
According to Li Tianbing, director of the general manager office of Hanfeng Sustained Release Fertilizers (Jiangsu) Co., Ltd., the technology uses patented microcrystalline paraffin wax and carbon as a sulfur coating outer coating, which fully guarantees the controllability of nutrient release from fertilizers. The nutrient released is more efficiently transported into the plant and transformed, promoting the growth of the plant's primary and root hairs, making the roots coarse and coarse, and increasing the absorption capacity.
According to reports, the carbon energy used in this technology is extracted from natural plants and contains 2,388 active ingredients that can be absorbed by plants together with nutrients, activate plant potential, and promote the physiological and biochemical reactions of plant cells and various invertase enzymes. Improve the ability of plants to take up nutrients, improve the activity of nutrients in plants, meet the full nutritional needs of crop growth, and can effectively promote the improvement of crop resistance, maximize the crop gene potential.
