摘　　要：为探究不同微生物菌剂对烤烟根际土壤微生物群落多样性的影响,对烟株施加不同菌剂处理的烤烟土壤进行了土壤理化性质、微生物群落多样性及结构组成变化的分析。结果表明:不同微生物菌剂处理后烤烟土壤有机质、总氮和有效磷含量均增加,而土壤pH值无明显变化;与CK相比,T2处理土壤有机质、总氮和有效磷含量分别增加31.36%、43.48%和23.95%,土壤中细菌和真菌多样性及丰富度均增加,其中细菌优势菌门为放线菌门、变形菌门、厚壁菌门、绿弯菌门和酸杆菌门;真菌优势菌门为子囊菌门、unclassified_k__Fungi和担子菌门。总的来说,微生物菌剂处理增加土壤有机质、总氮和有效磷含量,影响土壤微生物群落组成。To investigate the effects of different microbial fertilizers on the soil microbial community diversity of flue-cured tobacco roots,the soil physical and chemical properties,microbial community diversity and structure composition of flue-cured tobacco soil treated with different microbial fertilizers were analyzed.The results showed that the organic matter,total nitrogen and available phosphorus content of flue-cured tobacco soil increased after treatment with different microbial fertilizers,while the pH value of soil did not change significantly.Compared with the CK treatment,the organic matter,total nitrogen and available phosphorus content of the T2 treatment increased by 31.36%,43.48%,and 23.95%,respectively.The bacterial and fungal diversity and richness of T2 treatment in the soil increased.The dominant bacterial phylum of T2 treatment was Actinobacteria,Proteobacteria,Firmicutes,Chloroflexi,and Acidobacteria.The dominant fungal phylum of T2 treatment was Ascomycota,unclassified_k__Fungi,and Basidiomycota.In summary,microbial fertilizer treatment increased soil organic matter,total nitrogen,and available phosphorus content and affected the composition of soil microbial community.
