Microplastics and heavy metals (HMs) in soil pose significant environmental health risks, yet the interactions between mulch film residues HMs, their effects on maize productivity, remain poorly understood. This study examined impacts of long-term traditional polyethylene (TMF) biodegradable (BMF) properties, root accumulation arbuscular mycorrhizal fungi (AMF) community, productivity under open field conditions. TMF significantly increased total carbon (TC), C/N ratio, bioaccumulation coefficients (BACs) arsenic (As) cadmium (Cd) while lowering pH water content. These changes altered AMF colonization enriched Paraglomus genus, leading to enhanced leaf antioxidant activity reduced chlorophyll content, although growth was not statistically affected. In contrast, they improved nutrient availability (e.g., nitrogen phosphorus), TC pH. Notably, BMF decreased BACs As Cd, spore density without altering community structure, ultimately biomass. were associated with BMF’s ability lower chelate thereby mitigating bioavailability promoting plant growth. Furthermore, abundance species, particularly from Claroideoglomus facilitated metal chelation HM plants. The findings underscore potential for co-remediation microplastics highlighting importance mulching strategies sustainable agriculture.
