There is a strategic approach to fertilizer reduction and green efficiency

On May 15th, at the long-term fertilizer reduction and efficiency test and new fertilizer demonstration field meeting held in Dezhou, Shandong, the results of the 30-year fertilizer positioning monitoring test at the Dezhou Experimental Station of the Chinese Academy of Agricultural Sciences gave the answer: the combination of organic and inorganic fertilizers is to achieve high yields A theoretical system for the coordinated development of fertilization and environmental protection; the development of new high-efficiency fertilizers and the reduction of fertilizer efficiency through fertilizer efficiency is another strategic way to solve the environmental contradictions of high-yield fertilization and achieve green production.
Chen Mengshan, secretary of the Party Leadership Group of the Chinese Academy of Agricultural Sciences, characterized the results of this fertilizer positioning monitoring test as a national strategic scientific research result.
Participating experts believed that the two important results answered the major propositions of "reduction of chemical fertilizers and green efficiency".
The leaders of the Ministry of Agriculture and the relevant departments and bureaus of the Chinese Academy of Agricultural Sciences, as well as experts from the Soil and Fertilizer Station of the Agricultural Department of Shandong, Shanxi, Hebei and Henan, and the Academy of Agricultural Sciences inspected the experimental station's long-term positioning monitoring test group for fertilizer reduction and efficiency, and the creation of green and super high-yield fertilizers.
After the establishment of a demonstration field for experiments and fertilization systems, a long-term positioning monitoring test group and value-added fertilizer green and super high-yield, it was stated that the organic-inorganic combined fertilization positioning monitoring test group carried out by the Dezhou Experimental Station is the most complete and long-lasting positioning test in the world.
Brilliant.
According to Zhao Bingqiang, head of the Dezhou Station of the Chinese Academy of Agricultural Sciences and chief scientist of new fertilizers and fertilization technology, since 1986, the Dezhou Experimental Station has successively deployed a batch of organic fertilizers to improve soil and chemical fertilizers in the two test bases of Yucheng and Lingxian.
A series of long-term positioning experiments with organic substitution and reduction as the main content has formed a long-term positioning experiment group of different fertilization systems featuring the combination of chemical fertilizers and organic fertilizers.
Zhao Bingqiang said that the conclusion of the 30-year long-term positioning test is: to achieve high yield and high quality, it is necessary to take the road of scientific fertilization with a combination of organic and inorganic fertilizers.
100% organic fertilizers are applied, and it is difficult for crops to obtain high yield and high quality in the short term; The environmental risk is small, and the environmental risk of phosphorus is high, but the risk of excessive application of organic fertilizer and nitrogen is still increasing; Huanghuaihai winter wheat-summer corn farmland organic-inorganic (half chemical fertilizer plus half organic fertilizer) combined fertilization is an effective way to solve the environmental contradiction of high-yield fertilization, achieve high-yield and high-quality, and coordinate the development of soil fertility and environmental protection.
It is understood that in addition to the combined application of organic and inorganic fertilizers, the new fertilizer innovation team of the Chinese Academy of Agricultural Sciences also cooperated with the Dezhou Experimental Station to establish a new concept of carrier synergistic fertilizer production, and created the use of biologically active synergistic carriers to improve the performance and functions of fertilizer products and develop high-efficiency fertilizers.
The technical approach of new products, the development of new value-added fertilizer industries, and the research and invention of value-added urea, value-added ammonium phosphate, value-added compound fertilizers and other new products are another strategy to realize fertilizer efficiency reduction, solve the environmental contradiction of high-yield fertilization, and realize green production increase.
way.
Chen Youquan, deputy director of the Planting Management Department of the Ministry of Agriculture, after inspecting the positioning test, said that the 30-year fertilizer positioning monitoring test has provided a good answer to how organic fertilizers can partially replace chemical fertilizers.
It is of great significance for the development of chemical fertilizer reduction and green efficiency.
The public correctly understands chemical fertilizers and plays a positive role in avoiding demonization.
Chen Mengshan said that decades of scientific experiment data from the Dezhou Experimental Station clearly answered a series of major scientific questions such as how to reduce application and increase efficiency, and used practice to tell the industry what method to adopt.
