Effects of residual mulching films with different mulching years on the diversity of soil microbial communities in typical regions.

ABSTRACT: Polyethylene mulching film plays a critical role in agricultural production. To clarify the impact of residual film and microplastics on soil microorganisms, this study examined four cotton fields with different film coverage years in typical areas of Xinjiang and analyzed the changes in soil bacterial and fungal community structure and diversity under residual film and microplastics using high-throughput sequencing technology. The results showed that the residual film in the 0-150 mm soil layers and 150-300 mm soil layers at the same sampling point had spatial distribution characteristics of 60-70% and 30-40%, respectively. The short period of the 0-10 years film mulching treatment increased the soil microbial diversity of the cotton field, whereas continuous film mulching for 25 years si
