Chemical fertilizer utilization rate is an important index to evaluate the effect of scientific fertilization. Since the "14th Five-Year Plan", agricultural and rural departments at all levels have implemented in-depth chemical fertilizer reduction actions, promoted scientific fertilization and increased efficiency, and the utilization rate of chemical fertilizers has been steadily improved. According to scientific calculations, the fertilizer utilization rate of China's three major grain crops of rice, corn and wheat was 3.0% in 0 years, an increase of 0.0 percentage points over 0 years.

At the 4th Functional Fertilizer Industry Innovation and Development Conference held recently, the experts and scholars at the meeting agreed that microbial fertilizer is the key to saving fertilizer, controlling and increasing efficiency in order to achieve a balanced supply of nutrients between crops and soil; Functional microbial fertilizer is the basis for improving the utilization rate of chemical fertilizer, reducing the amount and increasing efficiency, and the synergist of yeast-derived fertilizer is one of the effective ways to achieve "zero growth" of chemical fertilizer.

Fu Chunhua, a first-class inspector of the Agricultural Production Materials and Cotton and Linen Bureau of the All-China Federation of Supply and Marketing Cooperatives, vice president of the China Agricultural Production Materials Circulation Association and chairman of the Organic Fertilizer Branch, said that agricultural enterprises should comprehensively, completely and accurately implement the new development concept, through the introduction of new technologies, new equipment and new standards, develop new quality productivity, promote the transformation of traditional industries to high-end, intelligent and green, and inject new impetus and new vitality into enterprises.

This year's No. 1 central document proposed, "further promote the large-scale yield improvement action of grain and oil crops." In the view of Zhang Xianxian, deputy director of the National Agricultural Technology Extension Service Center, large-scale yield improvement and density increase are the main means, and fertilizer and water synergy are the core support.

"In the future, the development of the fertilizer and water industry needs to focus on scientific and technological innovation, vigorously develop and promote new products, new technologies and new machinery, and accelerate the cultivation and development of new quality productivity in the field of fertilizer and water with the synergy, precision and wisdom and efficient utilization of fertilizer and water resources as the core, and the goal of 'promoting production, improving efficiency and ensuring safety'." Zhang Xianxian said.

"Through years of practice, we have gradually realized that microbial fertilizer synergists are an effective way to achieve the high-quality development of fertilizers in China, through the development of agricultural microbial agents, the application of organic (class) fertilizers, can inhibit soil acidification, improve and fertilize soil, increase soil carbon sink, remediate polluted soil, improve soil organic matter and other effects, can further achieve soil health." Shen Qirong, academician of the Chinese Academy of Engineering and professor of Nanjing Agricultural University, said.
