Effects of Biochar on the Growth of Chrysanthemum morifolium and the Structure and Function of Soil Bacterial Communities under Microplastic Pollution (PubMed, Huan Jing Ke Xue) - Jun 24, 2026 - "After biochar addition， plants adapted to the environmental stress from microplastics by regulating antioxidant enzyme activities and increasing the synthesis of chlorogenic acid and isochlorogenic acid A. Meanwhile， the composition of the rhizosphere microbial community of C. morifolium changed significantly， and high mass fraction microplastics and their coexistence groups significantly increased the Shannon and Simpson indices...The coexistence of PBAT and biochar enhanced key ecological functions of soil microorganisms， such as organic carbon source utilization and nitrogen fixation， thereby influencing nutrient cycling and energy conversion in the soil ecosystem. In summary， biochar addition helps alleviate the toxicity of microplastics to C. morifolium by regulating soil properties and changing the diversity and ecological functions of the microbial community， providing a theoretical basis for constructing new strategies for soil microplastic pollution..."
