摘      要：Arbuscular mycorrhizal fungi(AMF)provide essential nutrients to crops and are affected by ***-solubilizing bacteria(PSB),nitrogen-fixing bacteria(NFB),and AMF have mutually beneficial relationships with plants,but the effects of their interactions on plant growth by regulating rhizosphere fungal community have not been sufficiently *** this study,a greenhouse pot experiment was conducted to investigate the interactions between AMF and bacteria(PSB and NFB)on the growth of Lotus corniculatus ***,the role of rhizosphere fungal community in the growth of Lotus corniculatus *** explored using Illumina MiSeq high-throughput *** results showed that combined inoculation of AMF with PSB and NFB increased plant biomass,plant height,and fungal colonization *** richness,complexity,and stability of rhizosphere fungal community also increased after combined inoculation of AMF with PSB and/or NFB,particularly with *** addition,combined inoculation of AMF with PSB and NFB enriched the abundance of beneficial microorganisms,with Chaetomium and Humicola showing the greatest *** structural equation model showed that the interactions of AMF with PSB and NFB promoted plant growth by affecting fungal network structure and soil enzyme activities involved in carbon,nitrogen,and phosphorus *** findings provide evidence for the effects of interactions of AMF with PSB and NFB on rhizosphere fungal community and plant growth.
