作物轮作和间作是一种在各种农业生态系统中一直存在的可持续实践。这些管理措施可以抑制杂草，减少疾病周期，建立土壤有机质，增加地上和地下生物多样性，所有这些都可以提高伴生作物或后续作物的产量。在这里，我们提出了术语“轮作”和“间作价值”作为衡量这些效益的整体效果的一种方式。此外，我们阐明了如何量化不同的生态系统服务提供的轮作和间作，包括杂草和疾病的抑制，提高微生物群落，固氮使用的框架，这些服务如何支持其他作物在农业生态系统。通过提供一种识别和量化这些轮作和间作性状的方法，可以促进更好的轮作作物、覆盖作物和间作作物的育种。
Crop rotations and intercropping are an ever‐present sustainable practice across a diverse array of agroecosystems. These management practices can suppress weeds, reduce cycles of disease, build soil organic matter, and increase above‐ and belowground biodiversity, all of which improve the yield of a companion or subsequent crop. Here, we propose the terms ‘rotational’ and ‘intercropping value’ as a way to measure the overall effect of these benefits. Additionally, we articulate how to quantify different ecosystem services provided by rotational and intercrops including weed and disease suppression, enhancing microbial communities, and nitrogen fixation using a framework that accounts for how these services support other crops in agroecosystems. By providing a method of identifying and quantifying these rotational and intercropping traits, it may facilitate the breeding of better crops for rotations, for cover cropping, and for intercropping.
