摘要：In order to understand the remediation mechanism of cadmium-contaminated soils, pot experiments were conducted to study the effects of cadmium stress on soil microbial biomass and soil microbial diversity in Sasa argenteastriatus 5 mg/kg). Cadmium pollution significantly changed the structure of bacterial communities and promoted the growth and development of some tolerant bacterial species (hongkongensis and ovatus) at a low level of cadmium stress of 0.5mg/kg. High concentrations of cadmium caused stress that significantly inhibited the growth of Baclicus thermoamylovorans and Baclicus foraminis. These preliminary results reveal the response of soil microbial community structure to heavy metal pollution, and provide a theoretical reference for early warnings of trends in soil quality changes.
