According to the Institute of Applied Ecology, Chinese Academy of Sciences, stable fertilizers refer to a class of nitrogen-containing fertilizers that include urease inhibitors and nitrification inhibitors in the production process to extend the pot life, including binary or trinitrogenous nitrogen. Yuan fertilizer and simple nitrogen fertilizer.
It is understood that the fertilizer has already achieved large-scale production. Nearly 50 large-scale and above-scale enterprises have participated in the production nationwide. Currently, demonstration and promotion have been carried out in 25 provinces with a total of 260 million to 270 million mu of cultivated land, involving 27 kinds of applied crops. . Through a large number of tests and demonstrations, it has been confirmed that the stable fertilizer nutrients have an effective period of 120 days, which is 65 days longer than that of ordinary fertilizers, and can meet the demand for one-time fertilization. The fertilizer can increase the nitrogen utilization rate by 8.7 percentage points and increase the utilization rate of phosphorus by 4 percentage points. The average yield of various crops increased by 10% to 18%.
Experts stated that the Taihu Lake basin in Jiangsu Province is an important grain producing area. It takes a long time to cultivate, has a vast area of â€‹â€‹arable land, and has a huge amount of chemical fertilizers. This has also caused serious non-point source pollution in the area, resulting in serious eutrophication and production and living for local residents. Has brought bad effects. The Chinese Academy of Sciences attaches great importance to the treatment of non-point source pollution in the Taihu Lake Basin. This time, it cooperated with Jiangsu Huachang Chemical and jointly undertook the advanced general technology promotion project in the "Special Project on Taihu Lake Water Pollution Control" of the Jiangsu Provincial Science and Technology Department. It was fully promoted in the Taihu Lake Basin. The long-term sustained-release compound fertilizer is stable to reduce the non-point source pollution of agricultural fertilizers in the river basin, solve the problem of non-point source pollution caused by fertilization, and achieve greater social benefits.
Zhu Yujian, chairman of Huachang Chemical, expressed that it will use the opportunity of strategic cooperation between the two sides to achieve the continuous expansion of the industrial scale of stable fertilizers and the promotion and popularization of products, so as to continuously improve the agricultural production environment and ensure the future national food security.
