摘要

The effects of intercropping with four Bidens species (Bidens bipinnata, Bidens pilosa, Bidens parviflora and Bidens biternata) with grape seedlings on soil organic matter and soil enzyme activity under cadmium (Cd) stress were examined in order to provide the reference for grape production in cadmium pollution area. The results showed that intercropping treatments could increase the organic matter content in soil. In addition, intercropping treatments could increase the soil urease, invertase and catalase activities. Compared with monoculture, Intercropping with Bidens species decreased the soil phosphatase activity except B. parviflora. Therefore, soil enzyme activity and organic matter content could be increased by intercropping under cadmium stress, and the best material was B. parvifora.
