【 摘 要 】

The effects of mulching with four hyperaccumulator plants Crassocephalum crepidioides, Galinsoga parviflora, Youngia japonica, and Gnaphalium affine straws on soil enzyme activity of grape seedlings under cadmium (Cd) stress were studied by a pot experiment. The results showed that mulching with four kinds of hyperaccumulators straws, the soil catalase, phosphatase and sucrase activity were increased compared with the monoculture. Only the straw-mulch Y. japonica decreased the soil urease activity, which decreased by 0.10%, and others treatments all increased the soil urease activity. In conclusion, the treatment of G. affine is the best, C. crepidioides followed it.
