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][5]. 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 Journey - 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 in 2012 [4]. - The team discovered a "seesaw effect" between root nodule bacteria and aflatoxin-producing fungi, leading to the innovative coupling of these two research areas [4]. Group 3: Policy Support and Implementation - Since 2021, the Chinese government has emphasized increasing soybean production capacity and has shown growing interest in peanuts, with specific policies set for 2025 and 2026 to expand peanut cultivation [6]. - The ARC technology has been demonstrated in 22 provinces, showing strong resistance and quality improvement characteristics, with reported yield increases of over 15% for soybeans and 19% for peanuts [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 to expand its demonstration area to 3 million acres by 2025 and potentially to 30 million to 50 million acres in the next 3 to 5 years [7]. - The focus on technological innovation is seen as a key driver for increasing the yield of oilseed crops, contributing to national food security and the implementation of carbon neutrality strategies [7].
