"Improving the effective utilization of fertilizers and reduce the cost of agricultural production, fertility, in the amount of chemical fertilizers by as little as possible under the precondition of ensuring food security." This is the news in a few days ago, held in Weifang in Shandong, "the national environmental protection and soil fertilization efficient feature will be" heard on the development trend of fertilizer.
     It is understood that the input of chemical fertilizers in agricultural production into account the four, Chinese farmers spent 400 billion yuan every year to buy fertilizer, the data show that the 20th century, 50's, 70's and 90's, China's chemical fertilizer per kg of grain can yield 15 kg, respectively, 9 kg and 7 kg, and in the same amount of fertilizer, food production is declining. In particular as a result of excessive fertilization and the resulting decline in the quality of agricultural products, such as surface water pollution problem, has attracted more and more attention. Experts believe that the future of fertilizer should be the focus of the study how to improve the efficiency and utilization, and strive in the next 30 years, the domestic fertilizer industry the number of the implementation of the quality of alternative development strategies, to control the supply of chemical fertilizers 50 million tons less than in the non-increase or a small number of the premise of increasing the amount of chemical fertilizers, the fertilizer use efficiency by increasing food security.
     At the meeting, the prospects for agriculture industry experts with the current status of China's fertilizer industry had a wonderful discussion. They think that, first of all, through the release of fertilizer nutrients model modified in order to make fertilizer efficiency to the slow-release fertilizer nutrients, release of modified focused on efficiency, the development of sustained-release, controlled release fertilizer; followed by nutrient compound fertilizer ( mixed) modified so that fertilizer efficiency, the current developed composite (mixed) fertilizers of nitrogen, phosphorus and potassium nutrient consumption can account for the total amount of 70% ~ 80%, while China has only 30%; the third by the organic-inorganic composite (mixed) fertilizers to make fertilizer efficiency composite; IV to develop and improve manure fertilizer formula allows fertilizer efficiency, the current formulation of international fertilizer industry development models include the large European countries and the formulation of American States model of BB fertilizer small formula. In addition, fertilizer production technology through innovation and continuing to expand the new features of fertilizers to improve nutrient use efficiency of fertilizers as well as the new 21st century, one of the important fertilizer.
      Tenth National People's Congress Standing Committee, the Energy Advisory Committee of Experts of the State Council, deputy director of the road and made out to be "scientific fertilization boost the healthy development of fertilizer industry special report", the Chinese Academy of Engineering made Liu Gengling "China fertilizer industry and modern agriculture Construction "report, the state soil testing laboratory fertilization, director of the Center were made white by the way," the key to efficient fertilization technology research and the construction of modern agriculture in China, "the report, China's fertilizer industry, the annual meeting, chief expert of experts, land experts in the hospital president of CAO Kai soil microorganisms and the process of agro-ecological as well as to explore key technologies and efficient application of the effective ways to promote the use of an in-depth and detailed exposition. From the National People's Congress, the Ministry of Agriculture, Ministry of Science and Technology's leadership, the Chinese Academy of Engineering, Chinese Academy of Agricultural Sciences, Northwest Agriculture and Forestry University of Science and Technology of China's scientific research on behalf of institutions such as the well-known experts and scholars, provincial and municipal administrative departments Dohi the person in charge, fertilizer manufacturers, distributors and large grain on behalf of about 200 people attended the meeting.
      The meeting of experts by the Chinese fertilizer industry, the annual meeting, the Chinese fertilizer network, co-sponsored People's Government of Changle County, Shandong Fertilizer industry welfare Dragon Limited. It was also held, "China's first settled in the land of experts Hospital of Shandong Fertilizer Co., Ltd. Dragon welfare opening ceremony," CAO Kai-president of the hospital land experts at the meeting read out a proposal and sent the whole society's initiative to save the soil. (Jun)
