Abstract Intercropping aims to exploit complementary and facilitative interactions between species to improve capture and efficiency in the use of resources, and yield and profit per unit land and time. This review uses the ecological theory of intercropping to investigate the agronomic benefits and drawbacks of legume-oilseed intercropping and its place in mechanised broadacre agriculture. Complementary, competitive and facilitative interactions between species are analysed with a focus on nutrients and water in a range of legume oilseed pairings including pea-canola, soybean-sunflower, and chickpea-flax. Of the 41 studies investigated, 35 report yield, nutrient-use efficiency, or economic benefits of legume-oilseed intercropping. Legume-oilseed intercrops appear to negate many of the agronomic and technical issues associated with the more traditional cereal-legume pairings, and offer novel benefits such as the break-crop advantage to cereal dominant systems, and allelopathic pest repellence. While many of the traditional constraints to manage intercrops in broadacre mechanised systems appear to be tractable, this review also identifies priorities for further research and development of legume-oilseed intercrops. We conclude that legume-oilseed species pairings may have potential as commercially viable, large scale intercrops, as an effective means to improve productivity in broadacre mechanised agricultural systems.

机械化大田农业中豆科油料间作——综述

摘要 间作旨在利用物种之间的互补和促进相互作用，以提高资源利用的捕获和效率，以及单位土地和时间的产量和利润。本综述使用间作生态理论来研究豆科油料间作的农艺效益和缺点及其在机械化大田农业中的地位。分析了物种之间的互补性、竞争性和促进性相互作用，重点分析了一系列豆类油籽配对（包括豌豆-油菜籽、大豆-向日葵和鹰嘴豆-亚麻）中的营养成分和水分。在调查的 41 项研究中，有 35 项报告了豆科油料间作的产量、养分利用效率或经济效益。豆类-油籽间作似乎消除了与更传统的谷物-豆类配对相关的许多农艺和技术问题，并提供了新的好处，例如对谷物优势系统的断作优势和化感病虫害驱避。虽然在大面积机械化系统中管理间作的许多传统限制似乎是可以解决的，但本综述还确定了豆科油籽间作进一步研究和开发的优先事项。我们得出的结论是，豆类-油籽物种配对可能具有商业上可行的大规模间作潜力，可以作为提高大面积机械化农业系统生产力的有效手段。虽然在大面积机械化系统中管理间作的许多传统限制似乎是可以解决的，但本综述还确定了豆科油籽间作进一步研究和开发的优先事项。我们得出的结论是，豆类-油籽物种配对可能具有商业上可行的大规模间作潜力，可以作为提高大面积机械化农业系统生产力的有效手段。虽然在大面积机械化系统中管理间作的许多传统限制似乎是可以解决的，但本综述还确定了豆科油籽间作进一步研究和开发的优先事项。我们得出的结论是，豆类-油籽物种配对可能具有商业上可行的大规模间作潜力，可以作为提高大面积机械化农业系统生产力的有效手段。
