For a long time, the low utilization of common chemical fertilizers and the resulting environmental pollution have been a major problem that has plagued agricultural production. Relevant statistics show that the utilization rates of nitrogen, phosphorus, and potassium fertilizers are 30%-35%, 10%-25%, and 35%-50%, respectively. Loss of active ingredients in fertilizers causes losses of up to more than 100 billion yuan each year. Taking nitrogen as an example, more than 16 million tons of nitrogen are lost each year, which is equivalent to the fact that more than 1,000 fertilizer companies throughout the country have poured their output into the fields in vain. It is self-evident that improving the utilization rate of chemical fertilizers will increase the income of farmers, reduce waste of resources, and reduce environmental pollution. Since the beginning of this year, the Ministry of Agriculture has carried out soil testing, formula fertilization, and guided farmers' scientific fertilization, and has achieved great results. Some research units and enterprises are committed to researching and producing high-utility fertilizer varieties. A new type of controlled-release urea, which is basically synchronized with nutrient release and nutrient uptake during crop growth, was successfully developed by the Beijing Academy of Agriculture and Forestry Sciences. According to experts from the Beijing Academy of Agriculture and Forestry Sciences, this type of long-term controlled-release resin coated urea releases very little nitrogen when the nutrient demand is low at the seedling stage; when the crop grows at a vigorous stage, there is a large demand for nutrients. At the time, the nitrogen in the controlled release urea will be fully released to meet the needs of the crop. Experiments have shown that this urea can increase the nitrogen utilization rate to more than 60%, 30 percentage points higher than the normal urea utilization rate, 1/3-1/2 of the amount of fertilization, and effectively reduce the amount of leaching in fertilizers. Ammonia volatilization losses avoid soil, water and air pollution. The secondary pollution problem of controlled-release fertilizer coating has always been a concern in the industry. According to reports, this controlled-release urea is coated with a special, degradable resin material for urea. The moisture in the soil can be slowly infiltrated through the pores on the coating membrane, depending on the nutrient concentration inside and outside the envelope. Gradient difference, the transfer of nutrients to the soil for crop absorption. After the urea is used by the crop, the resin-coated shell of the controlled-release urea forms an empty capsule that can act as a “soil reservoirâ€: when it is abundant, it can absorb and store moisture; when it is dry in the field, it releases moisture. Play the role of water conservation, conservation, drought resistance. Experts said that the application of this controlled release urea will not only significantly increase production and increase income of wheat, corn, rice, cotton, flowers, fruit trees and sugarcane crops, but also reduce nitrate content, improve nutrient composition and food safety due to uniform feeding. . The quality of crops has been improved to meet the requirements of pollution-free and healthy foods. 95% of finished products have reached Class A standards. It is understood that Beijing First Innovative Fertilizer Manufacturing Co., Ltd., which is responsible for the production of this controlled release urea, has already produced controlled-release urea with different release days of 30, 60, 90, 120, 180, 220, and 300 days. The products are exported to Germany, Japan, the United States and other countries.
