The effects of arbuscular mycorrhizal fungi Glomus mosseae (+AMF) on the growth, nutrient uptake and leaf photosynthetic characteristics of alfalfa (Medicago sativa) under salt stress were studied. In alfalfa, 100 mM salt stress had no obvious effect on plant growth, nutrient content and photosynthetic capacity, however, 200 mM salt stress significantly inhibited biomass accumulation and NPK uptake. In addition, 200 mM salt stress led to decreased photosynthetic carbon assimilation capacity and lower PSII and PSI activity levels. Cultivation of alfafa with +AMF promoted biomass accumulation and uptake of nutrients, increased its underground growth, and promoted accumulation of P over N and K. +AMF increased PSII and PSI activities in alfalfa leaves under salt stress, and increased the electron transfer ability of PSII donor and acceptor sides. +AMF not only made alfalfa have relatively high stomatal conductance under salt stress, but also significantly enhanced its ability to utilize CO₂.

丛枝菌根真菌Glosus mosseae（+ AMF）对紫花苜蓿（紫花苜蓿）生长，养分吸收和叶片光合特性的影响）在盐胁迫下进行了研究。在苜蓿中，100 mM盐胁迫对植物生长，养分含量和光合能力没有明显影响，但是200 mM盐胁迫显着抑制生物量积累和NPK吸收。此外，200 mM盐胁迫导致光合碳同化能力降低，PSII和PSI活性水平降低。+ AMF种植苜蓿可促进生物量积累和养分吸收，促进地下生长，并促进P在N和K上的积累。 PSII供体和受体双方。+ AMF不仅使紫花苜蓿在盐胁迫下具有较高的气孔导度，而且显着增强了其利用CO的能力₂。
