Abstract

Soil bacteria and fungi play key roles in ecosystem functioning and the maintenance of soil fertility. Many studies have been carried out to assess the effects of plant on microorganism communities in different environments. However, little is known about whether turfgrass establishment affects soil microbial community. Therefore, in the present study, the microbial diversity in turfgrass soil and vacant land soil were studied by high-throughput sequencing technique, and the corresponding analysis of microbial composition were conducted. The results showed that the bacteria and fungi in the soil of turfgrass are richer than that of vacant land. The difference of soil microbial community at the genera level is more significant than that at phylum level. Among bacteria, a total of one dominant genus and 91 non-dominant genera were shared by the two samples. Five dominant genera and 66 non-dominant genera were present only in sample CP4 (turfgrass soil), and 13 dominant genera and 17 non-dominant genera only in sample CP0 (vacant land). Among fungi, a total of 5 dominant genera and 71 non-dominant genera were shared by the two samples, 8 dominant genera and 23 non-dominant genera were present only in sample CP4, and 6 dominant genera and 20 non-dominant genera only in sample CP0. The results also indicated that both dominant and non-dominant microbial populations differed greatly in the two samples, as did the overall soil microbial community structure. This study provides previously unknown information regarding the impact of turfgrass establishment on soil microbial communities and also lays a foundation for further investigations into microbiota in turfgrass soil.
