摘要

The widespread existence of microplastics (MPs) in soil has been extensively demonstrated, and their presence would ineluctably change soil physicochemical properties and microbial community composition. However, there is limited understanding of how MPs affect soil microbial assembly. In this study, three different polymer types of MPs, i.e., high-density polyethylene (HDPE), polystyrene (PS), and polylactic acid (PLA), with the same particle size (100 & mu;m) and dose (2%) were applied under the planted and unplanted condition, Pennisetum alopecuroides was chosen as a model species. Plant growth parameters, soil physicochemical properties, and microbial communities (including bacteria and eukaryotes) were determined. The assembly and the cooccurrence network of microbial communities were analyzed. Results revealed that the effect of MPs on soil physicochemical properties was type-dependent and could influenced by the presence of P . alopecuroides. MPs could enrich bacterial genera related to nitrogen cycle and some pathogens of eukaryotes. The presence of MPs changed bacterial and eukaryotic community assembly, in which diversity drove the deterministic/stochastic assembly processes. MPs addition increased the complexity of bacterial network, while had a minor effect on eukaryotic network. The inhibition of MPs on P . alopecuroides growth decayed over time, HDPE MPs was more harmful to P . alopecuroides growth than PS and PLA MPs. Our findings enormously improved our comprehensions of MPs-induced ecological impacts and interactions of soil bacterial and eukaryotic communities .
