Enhance nitrogen and phosphorus utilization of maize, rice, wheat and other crops, yield 10%, while its cost price, but higher than ordinary fertilizer 2% to 3%. March 24, the CAS Shenyang Institute of Applied Ecology Research Fellow WU Zhijie introduction, led by his commitment to the "Eleventh Five-Year" National Key Technology Program, "created a new and efficient fertilizer" has passed the Ministry of Science and acceptance. The results highlight that this study has also been included in the national "five-second" Technology Support Program.
Fertilizer is the food crops, increase the contribution rate of 50% or more. Serious constraint for the efficient use of fertilizer and fertilizer resources, industrial development, major and difficult issues, the CAS Shenyang Institute of Applied Ecology, based on original innovation and integrated innovation, focusing on the nitrogen / phosphorus release technology, optimization of fertilizer nutrients in high technology, non-water soluble Potassium mineral resource efficient use of technology, sound production technology of organic fertilizer and other major common research on key technologies and breakthrough.
Development of long-term slow release fertilizer in the study and application of topic, the Institute of fertilizer for the validity of a short, low nutrient use and environmental pollution caused by fertilizer and other issues, and initiating the activation of phosphorus inhibitor synergies and technology research, and ultimately broke phosphorus fertilizer into the soil immediately after the technical problems are fixed, so that utilization of phosphorus in an average of 4.8 percentage points. The technology also allows extended nutrient nitrogen to 120 days to reach 2 times the period of ordinary fertilizer to 2.5 times, to achieve the long-term slow-release fertilizer and one-time basal application of urea-free fertilizer, nitrogen utilization increased 8.7 percentage points on average.
At present, the core technology as the basis of the results of the production of fertilizer comprehensive technical specifications of new products have reached international advanced level, in maize, rice, wheat and other 27 kinds of crops on the average yield increase of 10% or more. Today, the results have been in the Shenyang Branch of the new fertilizer companies implement technology into several companies, controlled release fertilizer to build six production lines, forming a group of long-acting slow-release fertilizer brand, promote an area of ​​200 mu. Related technologies have been developed based on 27 special fertilizer formula, including 22 provinces, including Liaoning, established 66 technology demonstration, involving the formation of 28 crops of rice a long-term slow-release fertilizer experiment and demonstration network in the country be promoted.
By the end, "created a new and efficient fertilizer" project has developed 69 new products, new materials, Class 8, 26 kinds of new technology, the new device 17, and set up 31 pilot line, fertilizer demonstration area totaled 120 million acres. (Zhao Jing)
