It is well known that the application of chemical fertilizers plays a very important role in increasing crop yields, but due to its low utilization rate (nitrogen utilization rate is about 15%-30%), it also brings environmental pollution and agricultural product quality. How to improve the quality of agricultural products, save resources, reduce environmental pollution, reduce costs, and improve the utilization rate of fertilizers has become an urgent problem for the world's agriculture.
Based on the patented technology of controlled release fertilizer of Beijing Academy of Agricultural and Forestry Sciences, Beijing Shouli Fertilizer Manufacturing Co., Ltd. has developed the “SGL†brand controlled release fertilizer for field crops, which has solved the problem of large-scale crops in developed countries such as Europe and America. The application problem is half the price of similar foreign products. Relevant experts believe that the fertilizer is a new generation of traditional fertilizer, from the slow release fertilizer to the controlled release fertilizer stage, can completely change the instability and negative impact of slow release fertilizer. At the same time, it is also an environmentally friendly fertilizer in the 21st century, a revolution in fertilizer.
According to the company's technical experts, the Institute of Plant Nutrition and Resources of the Beijing Academy of Agricultural and Forestry Sciences has developed a new type of controlled-release slow-release fertilizer around the development direction of the world's new fertilizers, and has developed a zeolite-coated urea with independent intellectual property rights. And two kinds of controlled slow release fertilizers with "controlled release resin coated urea". In 1997, the technology won the national invention patent and the national key new product certificate, and the technology is leading in the country and reaching the international advanced level.
Researcher Wu Yuguang, a technical expert at the company, said that controlled release fertilizer is like putting "clothes" of different thickness on ordinary urea or ternary compound fertilizer. According to the fertilizer characteristics of different crops, 30 days can be produced by controlled coating technology. , 60 days, 90 days, 120 days and other different days of slow release fertilizer. Therefore, it is controllable and "smart".
Compared with general chemical fertilizers, controlled release fertilizers have the following remarkable features: First, they can increase fertilizer utilization rate by 10%-30%; second, fertilizer application on most crops can meet the requirements of the whole growth period of crops, saving labor and labor; It is possible to prepare various special fertilizers according to soil conditions and crop varieties, and it is convenient to apply; Fourth, planting and fertilization are completed once, no burning of seedlings, no damage to roots; fifth, saving one-third of nitrogen fertilizer application, and small fertilizer loss; It can reduce pollution to the environment and improve the quality of agricultural products; it can also increase crop yield by 8%-20% and increase income.
Mr. Li Weiguang, the chairman of the company, told the reporter that the company has developed long-acting and controlled-release corn special fertilizer, wheat special fertilizer, rice special fertilizer, cotton special fertilizer, potato special fertilizer, soybean special fertilizer, vegetable special fertilizer and flower special. Ten series of more than 100 varieties of fertilizers, currently can produce 20,000 tons of coated ternary compound fertilizer, 3,000 tons of coated urea, the supply of products is in short supply, and some products are exported to Japan and Europe and the United States. Demonstration and promotion in Beijing, Hebei, Inner Mongolia, Heilongjiang, Liaoning, Shandong, Henan, Jiangxi and other places, welcomed by farmers and friends. The company is expanding its production scale to meet market demand.
