The United Nations Food and Agriculture Organization (FAO) statistics show that, in increasing the yield per unit area, the effect of fertilizer on the yield of 40% - 60%. In China, the utilization ratio of fertilizer and fertilizer efficiency is generally low, the utilization rate of nitrogen fertilizer was lower than in developed countries 20%, rate of return than America and 1/3 in japan. According to statistics, China's annual N losses amounted to 13000000 tons, equivalent to the loss of about 32000000 tons of urea, equivalent to about 64000000000 yuan rmb. In addition, excessive fertilization is an important factor resulting in a waste of resources, environmental pollution, soil degradation conditions.

By the new fertilizer known as "environment-friendly fertilizer of twenty-first Century", especially the important members of new fertilizer industry -- stability fertilizer, will solve the problem. With the 2013 "No.1" documents issued, China's land will be changed from dispersed mode to the "family farm" mode, so that the land intensive utilization, agricultural mechanization and scale, which will further promote the new type of fertilizer in large area promotion and application in China, the new stability fertilizer is will become the mainstay of China fertilizer industry.

Statistics show that, the stability of fertilizer application in China covers an area of 357000000 mu, creating direct benefits 11813000000 yuan, reduce fertilizer investment of about 3250000000 yuan, the cumulative increase of 8050000000 kg of grain. In 2010 December, Chinese Academy of Sciences, Shenyang Institute of Applied Ecology, combined with 23 domestic large-scale fertilizer production enterprises and 22 Agricultural College, established the stability of fertilizer industry technology innovation strategic alliance, by the Ministry of science and technology as a "focus on fostering alliance", and the state government and the leadership of the many instructions, requirements in our efforts to popularize and application.

As early as in twentieth Century 60 time, Chinese Academy of Sciences, Shenyang Institute of Applied Ecology of long-acting fertilizer based research, which lasted 40 years, the 3 generation of scientists painstaking work, from agricultural soil chemistry, soil enzyme and other basic disciplines of chemistry and chemical engineering, machinery and interdisciplinary, cross, complementary, has developed a modified ammonium bicarbonate, urea, nitrogenous fertilizer long-acting synergist -- fertilizer uplift and enhanced ammonium No.1, long-acting compound (mixed) fertilizer additive NAM and corresponding all kinds of special fertilizer, as well as the multielement biological organic fertilizer technology and variety.

The CAS Shenyang Institute of Applied Ecology fertilizer engineering technology research center of technical personnel, the stability of fertilizer has a long period of fertilizer efficiency, nutrient use efficiency of high effect, stable supply of nutrients, yield obviously, reduce the non-point source pollution, and can be widely used in grain crop and economic crop production, is a new type of fertilizer, lower cost, simpler process, the most widely used, the most suitable species for China agricultural field application and promotion, china. According to estimates, farmers use fertilizer per acre stability only need to increase the investment 10 yuan.

According to the introduction, the stability of fertilizer by adding urease inhibitor and nitrification inhibitor to modulate the activity of soil microorganism during production, hydrolysis and nitrification of slow urea ammonium nitrogen denitrification, so as to achieve nitrogen fertilizer slow release fertilizer and reduce a loss, the inhibitor is the core stability of fertilizer. This technology is mainly based on soil enzymology principle, synergistic effect and principle of the increase of ammonium nutrition using urease inhibitor and nitrification inhibitor environment friendly, through the form of proportional control into the soil nitrogen, increase the nitrogen assimilation efficiency, control of nitrogen loss, prolong the period of fertilizer effect, improve the utilization rate of nitrogen fertilizer, and increase crop yield.
