在长期耕作和施肥试验中，菌根对作物产量和土壤生态系统功能的影响。

众所周知，农业管理会影响丛枝菌根（AM）真菌，但对于农民是否应该对 AM 共生进行管理还存在争议。我们在一项长期（14 年以上）的耕作和施肥试验中，对小麦根部连续三年的AM 真菌群落定殖情况进行了评估。对菌根、作物表现和土壤生态系统功能之间的关系进行了量化。耕作、施肥和连续单一栽培都降低了AM真菌的丰富度，并使群落组成趋向于由少数原始类群占优势。耕作和/或施肥抑制了根瘤菌和多米尼卡菌的生长，在所有样本或免耕样本中，根瘤菌和多米尼卡菌的丰度以及AM真菌的丰富度与土壤团聚稳定性和养分循环功能呈正相关。在田间，小麦产量与 AM 真菌丰度无关，与 AM 真菌丰富度呈负相关。在一项补充性玻璃温室研究中，来自未施肥、免耕地块的土壤接种物提高了小麦的生物量，而接种来自施肥地块和常规耕作地块的土壤的小麦则出现了中性或抑制生长的现象。这项研究证明了低投入和传统农业耕作方法对 AM 共生的不同影响，并强调了在管理菌根以实现更可持续的农业生态系统时，同时考虑作物产量和土壤生态系统功能的重要性。

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.
