Abstract:

Continuous cropping obstacles have significantly impacted the yield and quality of Perilla. To explore the mitigation effects of microbial agents on Perilla’s continuous cropping obstacles, two different arbuscular mycorrhizal fungi (AMF), which were Rhizophagus intraradices (RI) and Funneliformis mosseae (FM), were added to the continuous cropping soil. By measuring Perilla’s growth indicators, the physicochemical properties of rhizosphere soil, soil enzyme activity and microbial community structure, the differential effects of the two AMFs on Perilla growth were investigated. The results showed that the addition of AMF significantly increased the content of organic matter, total nitrogen, total phosphorus, and total potassium in the soil (P<0.05), enhanced soil urease and phosphatase activity, and increased the abundance of beneficial bacteria in the soil microbial community structure. The addition of AMF alleviated soil acidification and improved the growth status of Perilla. Compared to FM, RI had a more significant effect on Perilla growth and soil enzyme activity, while FM had a stronger ability to improve soil microbial community structure. This study elucidated the functional differences between the two AMFs in alleviating the continuous cropping obstacles of Perilla, provided a theoretical basis for the screening of microbial agents to mitigate these obstacles in future research.
