摘要

在没有化学防治及其负面影响的情况下，真菌病原体会造成巨大的产量损失，这就要求我们开发具有内在抗病能力的农业生态系统。草地生物多样性实验通常发现，植物物种多样性可降低病原体压力，但在农田中采用高生物多样性水平是否会产生类似效果，目前仍是未知数。我们通过将农田试验与土壤移植试验相结合，测试了播种不足的植物物种多样性是否能减少大麦病害，以及这种效应是通过地上还是地下机制介导的。正如预测的那样，大麦病害在播种不足的植物存在下有所减少。播种下的物种丰富度没有影响，但其丰富度会导致早期病害减少。地表机制是减少病害的基础。大麦产量随着播种不足物种丰富度的增加而略有下降，播种不足物种对产量的影响各不相同。我们确定了两个播种不足的物种（Trifolium repens 和 T. hybridum），它们对减少病害的贡献最大，并有可能提高大麦产量。此外，我们的研究结果表明，这是地面上的机制造成的。我们的研究表明，通过有针对性地选择播种不足的物种，可以在不牺牲产量的情况下改善农业生态系统的功能。在期刊博客上免费阅读本文的通俗摘要。

期刊介绍： Functional Ecology publishes high-impact papers that enable a mechanistic understanding of ecological pattern and process from the organismic to the ecosystem scale. Because of the multifaceted nature of this challenge, papers can be based on a wide range of approaches. Thus, manuscripts may vary from physiological, genetics, life-history, and behavioural perspectives for organismal studies to community and biogeochemical studies when the goal is to understand ecosystem and larger scale ecological phenomena. We believe that the diverse nature of our journal is a strength, not a weakness, and we are open-minded about the variety of data, research approaches and types of studies that we publish. Certain key areas will continue to be emphasized: studies that integrate genomics with ecology, studies that examine how key aspects of physiology (e.g., stress) impact the ecology of animals and plants, or vice versa, and how evolution shapes interactions among function and ecological traits. Ecology has increasingly moved towards the realization that organismal traits and activities are vital for understanding community dynamics and ecosystem processes, particularly in response to the rapid global changes occurring in earth’s environment, and Functional Ecology aims to publish such integrative papers.
