Soil organic carbon has played an essential role in global climate change, which controls CO2 concentration in the atmosphere. Arbuscular mycorrhizal fungi (AMF) play a vital role in organic carbon cycling coastal saline soil as an integral component of the microbial community. The study is based on the combination of Laboratory and field experiments to research the changes in soil microbial biomass, soil organic carbon-related enzymes activity in coastal saline soil, the effect of Enteromorpha prolifera biochar on microbial activity, soil organic carbon-related enzymes activity structure, and diversity of AMF communities, the role of AMF in organic carbon decomposition in coastal saline soil. The findings of this study showed that Enteromorpha prolifera biochar could improve soil's physical structure and chemical properties, increase the amount of organic carbon in the soil and the content of carbon components, increase soil enzyme activity and microbial population, and enhance crop agronomic characteristics by raising water conductivity, mineral content, and yield. The combined treatment effect of biochar and AMF was the main tactical method to increase the overall strength of Elymus growth and organic carbon of coastal saline soil in the current study. It also had a negative impact due to the increased salinity level, which is a significant scientific issue and can be controlled by the treatment effect of AMF that promotes plant growth by promoting salt tolerance capacity and improves the stability of soil aggregates.
