摘要:

豆科与禾本科作物间套作能促进农业可持续发展,优化利用资源,增强生物多样性,减少农业对石油产品的依赖。然而,传统间套作要适应现代农业的发展面临巨大挑战。中国科学家创新研发了大豆玉米带状复合种植(SMSI),该技术在提高国产大豆、玉米产能,保障国家粮食安全,促进农业可持续发展方面取得了显著成效。本文介绍了大豆玉米带状复合种植的基本内涵及其与传统间套作的重要区别;并阐释了该技术保证作物高产的核心原则及其未来发展前景。

Abstract:

The practice of intercropping leguminous and gramineous crops is used for promoting sustainable agriculture, optimizing resource utilization, enhancing biodiversity, and reducing reliance on petroleum products.  However, promoting conventional intercropping strategies in modern agriculture can prove challenging.  The innovative technology of soybean maize strip intercropping (SMSI) has been proposed as a solution.  This system has produced remarkable results in improving domestic soybean and maize production for both food security and sustainable agriculture.  In this article, we provide an overview of SMSI and explain how it differs from traditional intercropping.  We also discuss the core principles that foster higher yields and the prospects for its future development.
