Rhizosphere and Non-Rhizosphere Soil Microbial Community Structure and Diversity Asparagus officinalis L.
[Objective]The objective of this study is to investigate the characteristics of soil microbial community structure and diversity in both rhizosphere and non-rhizosphere soils of Asparagus officinalis L.,thereby providing theoretical support for the construction and maintenance of a healthy soil ecosystem.[Method]Soil community structure and the correlation between the community structure and soil nutri-ents in both rhizosphere and non-rhizosphere were analyzed using high-throughput sequencing and nutri-ent testing.[Result]The pH,TK and AK levels in the rhizosphere soil of Asparagus officinalis L.were found to be lower than those in non-rhizosphere soil.The OM,TN,HN,TP and AP were higher in rhizo-sphere soil.The bacterial diversity and richness,as well as fungal richness in rhizosphere soil,exceeded those in non-rhizosphere soil.However,the diversity of fungi in rhizosphere soil was lower than in non-rhizosphere soil.The dominant bacterial phyla in both rhizosphere and non-rhizosphere soils were Proteo-bacteria,Firmicutes,Acidobacteria,Actinobacteria,and Chloroflexi.Similarly,the dominant fungal phyla were Ascomycota and Basidiomycota.LEfSe analysis revealed that 14 bacterial taxa and 20 fungal taxa in rhizosphere soil were significantly different from those in non-rhizosphere soil.Redundancy analy-sis(RDA)indicated that pH had the most significant impact on soil microbial community structure.[Conclusion]This study expands our understanding of microbial diversity in the rhizosphere soil of As-paragus officinalis L.and provides a theoretical basis for the high-quality cultivation of Asparagus offici-nalis L.through modulation of the soil microbial community structure.
