非豆科作物间作改善土壤生物化学和作物生产力：一项荟萃分析

植物物种丰富的系统往往比缺乏物种的系统更有生产力。在农业生态系统中，通过包括豆类增加作物植物多样性通常会增加土壤氮(N)并改善土壤肥力；然而，这种非豆科混合作物的结果的普遍性是未知的。本文通过对174个个案的荟萃分析，探讨了目前全球非豆科作物间作的研究趋势，并量化了不同试验条件下间作对作物健康、土壤化学和微生物群落等农业生态系统生产力关键指标的影响。ICnl增加了植物生物量，抑制了病害，并提供了显著的产量优势。除磷和钾外，ICnl还增加了植物有效态土壤氮，与土壤微生物丰度的增加一起，与土壤有机质的增加呈正相关。这些积极作用在长时间（1年）、田间土壤条件和土壤pH [gt； 7]的试验中更为明显。ICnl改善了几种作物生产力指标，这可以增加可持续作物生产，特别是在长期和碱性土壤中实施时。

期刊介绍： New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
