【 摘 要 】

The effects of mulching with four hyperaccululator plants Youngia erythrocarpa, Galinsoga parviflora, Gnaphalium affine and Crassocephalum crepidioides straws on the soluble sugar content of P. frutescens under cadmium stress were studied by a pot experiment. The results showed that the straw-mulch C. crepidioides and G. affine increased the soluble sugar content of P. frutescens. But, the straw-mulch Y. erythrocarpa and G. parviflora decreased the soluble sugar content of P. frutescens. The soluble sugar content in shoot of P. frutescens for the treatments of mulching with straw of C. crepidioides and G. affine were 5.18% and 25.83% higher than control. In conclusion, the treatment of G. affine is the best, followed by C. crepidioides.
