Significant soil contamination of microplastics (MPs) by the application of agricultural mulching films has aroused global concern, however, the effects of conventional and biodegradable MPs on the dynamics of soil microbial communities and network patterns have not been sufficiently reported. In this study, we conducted a soil microcosmic experiment by adding low-density polyethylene and biodegradable MPs (PE and BD) into a black soil at the dosages of 0 % (CK), 0.1 % (low-dose, w/w), 1 % (medium-dose, w/w) and 5 % (high-dose, w/w), and soils were sampled on the 15th, 30th, 60th and 90th day of soil incubation for high-throughput sequencing.
