Yesterday interviewed the Institute of Applied Ecology of the Chinese Academy of Sciences was informed that the “Eleventh Five-Year†national science and technology support plan key project - the new high-tech fertilizer creation project passed the acceptance in Beijing. In the past five years, the project has won 2 national second prizes for scientific and technological progress, 36 kinds of new products have been developed, 22 experimental bases have been established, 9 technologies have been integrated, 35 domestic invention patents have been authorized, and they provide new product development and industrialization demonstration for the fertilizer industry. Technical support. China's new high-efficiency fertilizer technology innovation system has basically taken shape during the “11th Five-Year Plan†period.
According to Wu Zhijie, a researcher of the Shenyang Institute of Ecology, who is the convener of the project, focusing on the key and difficult issues that severely restrict the efficient use of fertilizer resources and the development of the fertilizer industry in China, they are based on original innovation and integrated innovation, with emphasis on the release of nitrogen/phosphorus slow release technology and control. We have carried out research and achieved breakthroughs in major key and common technical fields such as the release of envelope technology, efficient optimization of compound (mixed) fertilizer nutrients, efficient use of water-insoluble potash resources, and rapid production technology of harmless organic fertilizers.
It is understood that the inhibitor synergies and phosphorus activation technologies developed in this project have developed slow-release urea, long-acting slow-release compound fertilizers and other products. The product has a long period of fertilizer efficiency, and the effective period of nitrogen fertilizer is as long as 120 days. This achievement was obtained. In 2008, the National Science and Technology Progress Second Prize, the new crop controlled release fertilizer research and development and application of industrialization won the 2009 National Science and Technology Progress Award. This achievement laid a theoretical and technical foundation for the promotion of controlled-release fertilizers on field crops, and has broad application prospects.
In addition, the new crop controlled release fertilizer project is recycling waste thermoplastic resin coated film, sulfur modified resin coated film, thermoplastic and thermosetting resin multilayer composite film, solvent efficient recovery, product testing and quality control, and large-scale industrialization. The development has reached the international advanced level; for the first time, the industrialization and scale-up of the 3S controlled release technology has been realized for the manufacturing technology and industrialization of different-vessel speed-variable controlled-release fertilizers. The solvent-free in-situ reaction film-forming controlled release technology and the water-soluble resin coating have been developed. Controlled release technology combined with the industrialization of integrated technology. In addition, the topic of clean production technology for the production of potassium sulphate and aluminum hydroxide from Nehui Syenfeld has passed national appraisal of scientific and technological achievements, providing a new technical route and method for the potash fertilizer industry in China, and achieving the comprehensive utilization of non-water soluble potash resources. The goal is a green chemical representative for energy efficient and cleaner production.
The creation of a new type of high-efficiency fertilizer also made progress in the prevention mechanism and industrialization of bio-organic fertilizers, and established an industry-university research alliance that includes 22 companies, laying a solid foundation for the promotion and application of bio-organic fertilizers.
