Slow-release fertilizer promotion must be calculated environmental accounting

Sinochem New Network News On December 25th, in 2012, the National “Science and Technology Sanitation” campaign was launched in Linyi County, Shandong Province. During the event, Wang Zhixue, member of the Party Committee of the Ministry of Science and Technology, Yan Lixin, deputy director of the Department of Policy and Regulation of the Ministry of Science and Technology, Wang Yu, deputy director of the Department of Rural Science and Technology, and Guo Jiucheng, deputy director of the Shandong Provincial Science and Technology Department, and other leaders visited Jin Zhengda’s company in technological innovation. jobs.

Wang Zhixue, a member of the Party Committee of the Ministry of Science and Technology, visited the Jin Zhengda company’s scientific and technological innovation work, Wang Zhixue’s delegation, to listen to the company’s development history and status quo. In particular, the company’s report on promoting scientific and technological innovation and increasing cooperation between industry, universities, and research institutes. When he learned that the company had established a national high-level R&D platform such as the National Engineering Technology Research Center for Controlling Slow-release Fertilizers, National Engineering Laboratories, and Postdoctoral Scientific Research Workstations, he had hosted the National Science and Technology Support Programs for the “Eleventh Five-Year Plan” and “Twelfth Five-Year Plan” and obtained more than 30 awards. In the national and provincial major scientific research projects, Wang Zhixue fully affirmed Kim's efforts to develop strategic emerging industries and devoted himself to the slow development of controlled release fertilizer industry.

In Jin Zhengda's controlled-release fertilizer product display area, Wang Zhixue asked in detail about product features, advantages and promotion. Wang Zhixue emphasized that slow and controlled release fertilizers can effectively increase the utilization of fertilizers and reduce the use of chemical fertilizers. If China promotes such fertilizers in large areas, it is not simply economic benefits, but more importantly environmental benefits. Therefore, we must calculate Clear environment this big account. After learning that the company and the Nanjing Institute of Soil Science of the Chinese Academy of Sciences have conducted controlled-release fertilizers on greenhouse gases and ammonia volatilization in the Taihu Lake area, Wang Zhixue very much agrees. He suggested that China’s climate experts are currently studying energy conservation and emission reductions. Clean development mechanism, controlled-release fertilizers will make great efforts to conduct in-depth research on low-carbon agriculture. By then, we will have more right to speak in climate negotiations. At the same time, he also encouraged Kim Jong-tah to speed up the construction of the Controlled-Release Fertilizer Engineering Technology Research Center and handed in a satisfactory answer sheet for the innovation platform of the Ministry of Science and Technology.

According to Chen Hongkun, deputy director of the National Engineering Research Center for Controlled-release Fertilizers and deputy general manager of Jinzhengda, the carbon dioxide emissions from the production and application of nitrogen fertilizers in China account for approximately 8% of the country’s total emissions, if instead of controlled-release fertilizers Traditional nitrogen fertilizer can reduce nitrogen fertilizer consumption by about 7 million tons, and reduce N2O emissions by about 70,000 tons, equivalent to about 0.2 billion tons of carbon dioxide emissions. In the promotion of controlled-release fertilizers, the company calculated the environmental effects of controlled-release fertilizers while calculating the economic accounts for farmers. The data from the Taihu Lake for three consecutive years shows that while reducing the amount of nitrogen fertilizer application, controlled-release fertilizers can effectively reduce the ammonia volatilization by 18%–34% and runoff nitrogen by 6%–17%. Therefore, slow and controlled release fertilizers can ensure the high yield of rice while reducing the amount of nitrogen fertilizer and reducing the impact of nitrogen on the environment. According to Chen Hongkun, the National Controlled-release Fertilizer Engineering Research Center and the “Twelfth Five-Year Plan” National Science and Technology Support Program have strengthened the research on the slow and controlled release fertilizers on environmental effects and provided strong technical support for energy saving and emission reduction in agriculture. .
