20余年攻关让大豆、花生安全高产

Core Viewpoint - The ARC biological coupling technology, developed by a team led by Li Peiwu, addresses two major challenges in the soybean and peanut industries: aflatoxin contamination and low nitrogen-fixing efficiency, thereby enhancing both yield and quality of these crops [1][3][4]. Group 1: Technology Breakthrough - The ARC technology simultaneously controls aflatoxin contamination and promotes nitrogen-fixing by inducing root nodule formation in legumes, achieving a dual benefit of increased production and safety [3][4]. - The technology allows for a reduction in chemical fertilizer use by 20% to 40%, while increasing soybean and peanut yields by over 15% and 19% respectively, and achieving a 63% effectiveness in controlling aflatoxin-producing fungi [6][7]. Group 2: Industry Significance - Soybeans and peanuts are crucial for China's edible oil market, accounting for approximately 56% of the market share, and enhancing their production capacity is vital for food security [1][2]. - The technology has been recognized and promoted at a national level, with significant policy support aimed at increasing soybean and peanut production, including specific mentions in central government documents [6][7]. Group 3: Implementation and Impact - The ARC technology has been demonstrated across 22 provinces in China, with large-scale trials showing resilience against adverse weather conditions and significant economic benefits for farmers [6][7]. - The ongoing research and development efforts aim to expand the application of this technology to 3 to 5 million acres in the next 3 to 5 years, further solidifying its role in enhancing agricultural productivity [7].
