摘要:

连作障碍现象严重制约紫苏的产量和质量。为探究不同丛枝菌根真菌(AMF)对紫苏连作障碍的缓解效果,通过向连作土壤中分别添加丛枝菌根真菌(AMF)根内根孢囊霉(RI)和摩西管柄囊霉(FM),测定紫苏地上生长指标,结合土壤理化性质、土壤酶活性及微生物群落结构,探讨2种AMF对紫苏生长的影响。结果表明,添加2种AMF能显著提高土壤中有机质、全氮、全磷和全钾含量(P<0.05),提高土壤脲酶和磷酸酶活性,增加土壤微生物群落中有益菌丰度,连作土壤酸化趋势得到缓解,紫苏生长指标明显提高。2种AMF相比,RI在提高土壤酶活性方面影响更加明显,而FM改善土壤微生物群落结构的能力更强。研究阐明了2种AMF改善连作紫苏土壤的功能差异,为下一步筛选缓解紫苏连作障碍的微生物菌剂提供了理论依据。

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.
