Aims Long-time continuing cropping of peanut (Arachis hypogaea) would result in soil deterioration, which would seriously affect the productivity and the quality of peanut. Arbuscular mycorrhizal fungi (AMF) have been used as a fertilizer that may improve root microenvironment, increase nutrient uptake and stress resistance of the plants. This study investigated the effects of Funneliformis mosseae on peanut rhizosphere microenvironment under continuing peanut cropping.
Methods We conducted an experiment to examine soil properties, peanut productivity and quality between the treatments of: (1) peanut seedlings inoculated with F. mosseae in continuous cropping soil, and (2) peanut seedlings without the inoculation.
Important findings We observed that F. mosseae significantly enhanced the activity of sucrase, urease, alkaline phosphatase and nitrate reductase in soil, significantly increased the soil contents of total nitrogen, total phosphorus, total potassium, available phosphorus and available potassium. Meanwhile, the abundances of Aspergillus, Fusarium and Gibberella in the rhizosphere soil of continuous cropping were decreased, while the abundances of Gaiella was significantly increased comparing to the treatment without F. mosseae inoculation. In addition, F. mosseae significantly increased the peanut yield and quality, including protein, oleic acid and linoleic acid content. Our results suggested that F. mosseae improve the peanut rhizosphere environment, alleviate the obstacles of continuous cropping.
