Effects of Biodegradable Plastic Mulch Film on Cabbage Agronomic and Nutritional Quality Traits, Soil Physicochemical Properties and Microbial Communities

The long-term use of polyethylene mulch (PEM) films can cause plastic film residual pollution that has an adverse effect on soil health and crop quality. To address this issue, poly(butylene adipate-co-terephthalate) (PBAT), aliphatic–aromatic copolyester, is widely used in the production commercially biodegradable (BDM) films. BDMs alleviate reduce labor cost retrieving residues from field. effects BDM PEM agronomic nutritional quality traits cabbage cultivar ‘Sugan No. 35’, as well physicochemical properties microbial communities were analyzed during two consecutive years experiment. No significant difference was observed among three mulching treatments. Nonetheless, degradation reduced pH value increased organic matter content samples compared with mulching. In bacterial fungal communities, Proteobacteria Ascomycota most abundant phylum across all samples, respectively; relative abundance overall much lower than production.
