Abstract

The effects of Cyphomandra betacea seedlings intercropping with four hyperaccululator plant species (Bidens pilosa, Solanum photeinocarpum, Galinsoga parviflora, and Tagetes erecta) on soil enzyme activity under cadmium (Cd) stress were studied by a pot experiment. The results showed that intercropping treatments could increase the soil sucrase and soil urease activities. The soil catalase and soil polyphenol oxidase activities showed different promote or inhibit effects on different hyperaccumulator plants by intercropping compared to monoculture. Only intercropping with S. photeinocarpum, all soil enzyme activity increased compared to C. betacea monoculture. Therefore, intercropping could improve the soil enzyme activity under Cd stress, and C. betacea intercropping with S. photeinocarpum was the best.
