间作在我国具有悠久的历史，大量研究已表明，玉米与豆科作物间作不仅在提高作物群体产量方面具有一定优势，并且可以使植株地上部高效利用光温资源、地下部优化利用水分和养分资源，进而实现资源的协同增效，提高了旱地农田生产力。本文重点综述了玉米与豆科作物间作通过改善光、水、养分等利用提高旱地农田生产力的主要机理，解析了玉米与豆科作物间作通过优化作物品种、养分管理、空间布局、种植密度等农艺调控措施来提高旱地农田生产力的主要途径，并提出了玉米与豆科作物间作在应用中亟待解决的关键问题，旨在为合理构建适宜我国旱地农田的高产稳产和资源高效型禾豆间作模式提供有力的理论和技术支撑。

Intercropping has a long history in China. A large number of studies have shown that intercropping of maize and leguminous crops not only has certain advantages in increasing the crop yield at the population level but also enables the aboveground parts of plants to efficiently utilize light and temperature resources and the underground parts to optimize the utilization of water and nutrient resources, thereby achieving the synergistic enhancement of resources and improving the productivity of dryland farming systems. This paper mainly reviews the main mechanisms by which intercropping of maize with leguminous crops improves the productivity of dryland farmland through enhancing the utilization of light, water, and nutrients. It also analyzes the main approaches by which intercropping of maize with leguminous crops can increase the productivity of dryland farmland through optimizing agronomic control measures such as crop varieties, nutrient management, spatial layout, and planting density. Moreover, it presents the key issues that need to be addressed in the application of maize and leguminous crop intercropping. It aims to provide strong theoretical and technical support for the rational construction of high-yield, stable-yield and resource-efficient intercropping patterns of cereal and legume suitable for dryland farmlands in China.
