Effects of Variations in Soil Moisture and Phosphorus Concentrations on The Diversity of Arbuscular Mycorrhizal Fungi Community in An Agricultural Ecosystem

To elucidate the effects of phosphorus concentration and water management on arbuscular my-corrhizal fungi (AMF), field experiments were conducted in a farmland ecosystem (China). We examined the effects of different treatments, including drought and normal phosphorus, normal water and normal phosphorus, drought and low phosphorus, and normal water and low phos-phorus, on the AM fungal biomass, diversity, and community. The results showed that there were great differences in AMF fungi under different water and phosphorus concentrations. When under the suitable drought treatment, AMF became more abundant and more conducive to the growth of plants. The abundance of AMF varied with different phosphorus treatments, and the abundance of AMF in low-phosphorus treatments was higher, which is more suitable for plant growth. To un-derstand the influence of different phosphorus concentration and moisture content of AMF, can play a role in agricultural production for AMF provide better theoretical support. In conclusion, as water and phosphorus concentration change, the community structure of AMF constantly changes. Only under the appropriate water and phosphorus concentration processing can AMF play its role well. This study provides theoretical basis for rational fertilization and irrigation. By studying the influence of different water and phosphate of AMF diversity, found AMF how changes affect crop growth, has important research significance.
