摘要:
丛枝菌根真菌(AMF)能与自然环境中的多数陆生植物互利共生。间套作种植作为增加农田生态系统生物多样性的重要措施,能显著提高植物对农田环境中多种资源的利用率。在间套作体系中,AMF通过对农作物和土壤环境的影响,提高农田生态系统的经济产量并促进其可持续发展。本文从AMF对宿主植物根系特征的影响、AMF对宿主植物根际微生物群落结构功能的影响、AMF在改善土壤结构提高土壤肥力方面的作用、菌根植物间共生菌丝网络的养分资源传递分配等方面,阐述AMF对间套作体系中植物-土壤-微生物相互作用的影响及其机制,为AMF在农业方面的进一步应用提供理论基础。

Abstract:
Arbuscular Mycorrhizal Fungi (AMF) can interact with most terrestrial plants in the natural environment. Intercropping as an important measure to increase the biodiversity of farmland ecosystems can significantly increase the utilization of plants to multiple resources in the farmland environment. In the intercropping system,AMF improves the economic output of farmland ecosystems and promotes their sustainable development through the impact on crops and soil environment. In this paper,the effects and mechanisms of AMF on plant-soil-microbes interactions in intercropping systems are described in terms of the effects of AMF on root characteristics of host plants and on microbial community structure and function in rhizosphere of host plants,the role of AMF in improving soil structure and soil fertility,nutrient resources transmission and distribution in the symbiotic mycelium network between mycorrhizal plants,etc,providing a theoretical basis for the further application of AMF in agriculture.
Key words:  arbuscular mycorrhizal fungi  intercropping system  soil microbes  nutrient absorption  root characteristics  common mycorrhizal network
