In May 15th, in Shandong, Dezhou held a long-term test and less nitrogen fertilizer efficiency of new fertilizer demonstration site, Dezhou experiment station of Chinese Academy of Agricultural Sciences for 30 years, the fertilizer monitoring test results gives the answer: the science of organic and inorganic fertilizers, is to achieve high yield, fertilizer and environmental protection coordinated development theory; development of new fertilizer, implementation through the reduction of fertilizer efficiency, is another way to solve the contradiction between high yielding fertilization strategy environment and realize green production. Chen Mengshan, Secretary of the Party committee of Chinese Academy of Agricultural Sciences, identified the results of the fertilizer position monitoring test as a national strategic scientific research achievement. Experts believe that the two important results answered the "fertilizer reduction, green efficiency" of the major propositions.
The Ministry of agriculture, Chinese Academy of Agricultural Sciences, the relevant departments of the leadership and Shandong, Shanxi, Hebei, Henan four provincial Department of agriculture Dohi Station, inspected the Academy of experts of fertilizer efficiency experiment station less nitrogen long-term monitoring test group, added green fertilizer for super high yield fertilization system create test, long-term monitoring test group, value-added fertilizer green super high yield demonstration field after that, the Dezhou experiment station of organic and inorganic fertilizers positioning monitoring test group is the world's most complete experiment design, the longest, impressive.
According to the DeZhou Railway Station station, Chinese Academy of Agricultural Sciences new fertilizer and fertilization technology chief scientist Zhao Bingqiang, from the beginning of 1986, Dezhou experimental station in Yucheng and Lingxian County two test base in succession layout of a number of organic fertilizer to improve soil and organic fertilizer instead of reduction as the main content of the series of long-term experiment, formed by the combination of chemical fertilizer and organic fertilizer as the main characteristics of different fertilization systems long-term experiment group. Zhao Bingqiang said that 30 year long-term experiment conclusion is: to achieve high yield and quality, must take the road of scientific fertilization of organic and inorganic combination, 100% organic fertilizer, the short term is not easy to obtain high yield and high quality crops; environmental risk organic fertilizer nitrogen, phosphorus environment risk, but the excessive application of organic fertilizer the risk is still increasing; winter wheat in summer maize field (half organic and inorganic fertilizers plus organic manure fertilizers, half) is an effective way to crack the fertilization environment contradiction, realize high quality and high yield soil fertility and environmental protection coordinated development.
It is understood that, in addition to organic and inorganic fertilizer, Chinese Academy of Agricultural Sciences new fertilizer innovation team also coordinated Dezhou experimental station established carrier fertilizer new concept of efficiency, established the technical approach of developing highly efficient fertilizer new product performance and function, enhance the utilization efficiency of chemical fertilizer products bioactive carrier, to develop value-added new fertilizer industry, value-added urea, the invention of the value added of ammonium phosphate and compound fertilizer, a series of new products is to achieve the fertilizer efficiency reduction, and a strategic approach to achieve high yield production of green environmental contradictions and crack.
Chen Youquan, deputy director of the Ministry of agriculture planting industry management department of the experiment said after 30 years fertilization test monitoring is a very good answer to the organic fertilizer to replace chemical fertilizer, chemical fertilizer on less nitrogen, is of great significance in guiding the public green efficiency, correct understanding of chemical fertilizer, avoid demonizing play a positive role. Chen Mengshan said that the Dezhou experimental station decades of scientific experimental data clearly answered how to reduce the effectiveness of the application of a series of major scientific issues, and practice to tell the industry what kind of approach should be taken.
