20余年攻关让大豆、花生安全高产—— 科技与产业共生共赢的生动样本

Core Viewpoint - The ARC biological coupling technology, developed by a team led by Li Peiwu, has won the highest award at the 14th China Innovation and Entrepreneurship Competition, indicating its potential to enhance soybean and peanut production while addressing food safety concerns [1][3]. Group 1: Technology Breakthrough - The ARC technology addresses two major challenges in the soybean and peanut industry: controlling aflatoxin contamination and improving nitrogen fixation efficiency [2][3]. - The technology achieves "two fixes, three increases, and five reductions," which includes nitrogen fixation, carbon fixation, increased yield, efficiency, and safety, while reducing bacteria, losses, fertilizer use, costs, and carbon emissions [3][4]. Group 2: Research and Development Process - The research team began their work in 1999, focusing on the pain points of the soybean and peanut industry, and successfully developed a core technology for efficient aflatoxin detection by 2012 [3][4]. - They discovered a "seesaw effect" between root nodule bacteria and aflatoxin levels, leading to the innovative coupling of these two research areas [4][5]. Group 3: Policy Support and Implementation - Since 2021, the Chinese government has emphasized increasing soybean production capacity and has begun to pay more attention to peanuts, with specific plans for expansion in future policy documents [6]. - The ARC technology has been demonstrated in 22 provinces, showing strong resistance and quality improvement characteristics, with significant yield increases reported [6][7]. Group 4: Future Prospects - The Chinese Academy of Agricultural Sciences plans to launch a major research task in 2024 to further develop the ARC technology, aiming for a demonstration area exceeding 3 million mu by 2025, with potential expansion to 30 million to 50 million mu in the next 3 to 5 years [7]. - The focus on technological innovation is seen as a key driver for increasing oilseed crop yields and ensuring food security in China [7].
