摘要：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 indifferent environments. However, little is known about whether turfgrass establishment affects soilmicrobial community. Therefore, in the present study, the microbial diversity in turfgrass soil andvacant land soil were studied by high-throughput sequencing technique, and the correspondinganalysis of microbial composition were conducted. The results showed that the bacteria and fungi inthe soil of turfgrass are richer than that of vacant land. The difference of soil microbial community atthe genera level is more significant than that at phylum level. Among bacteria, a total of one dominantgenus and 91 non-dominant genera were shared by the two samples. Five dominant genera and 66non-dominant genera were present only in sample CP4 (turfgrass soil), and 13 dominant genera and17 non-dominant genera only in sample CP0 (vacant land). Among fungi, a total of 5 dominant generaand 71 non-dominant genera were shared by the two samples, 8 dominant genera and 23 nondominant genera were present only in sample CP4, and 6 dominant genera and 20 non-dominantgenera only in sample CP0. The results also indicated that both dominant and non-dominant microbialpopulations 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 establishmenton soil microbial communities and also lays a foundation for further investigations into microbiota inturfgrass soil.
