| 摘 要： | 将豆苗种植于人工模拟的重金属污染土壤中，其土壤中镉、铅污染物浓度分别为 0.3 mg/kg、 300.0 mg/kg。通过在土壤中投加不同比例的香菇根和皂素废渣，考察了其阻控土壤中重金属铅和镉对蔬菜污染的效果。结果表明:土壤中含有适量的香菇根和皂素废渣可促进植物豆苗的生长；当香菇根或皂素废渣的添加浓度为 30.0 g/kg时，对铅的阻控效率最高（阻控率分别达到 49%、19%），当皂素废渣的添加浓度为 10.0 g/kg时，对镉的阻控效率最高（阻控率达到 9%）。说明了香菇根和皂素废渣对土壤中铅和镉的污染都有一定的阻控作用。

| Abstract: | Bean seedlings were planted in simulated heavy metal contaminated soil with cadmium of 0.3 mg/kg and lead of 300.0 mg/kg， respectively. We investigated the inhibiting effects of waste residues on uptake of lead and cadmium heavy metals by vegetables with addition of different proportions of lentinus edodes root and diosgenin waste residues into the soil. It was found that the appropriate amount of lentinus edodes roots or diosgenin waste residues in soil could promote the growth of bean seedlings. When the addition of lentinus edodes root or diosgenin waste residues were 30.0 g/kg， the inhibiting effect of lead was best （the inhibiting rate were 49% and 19%， respectively）. When the addition of diosgenin waste residues were 10.0 g/kg， the inhibiting effect of cadmium was greatest （the inhibiting rate was 9%）. These results indicated that both lentinus edodes root and diosgenin waste residues had some inhibiting effects on uptake of lead and cadmium by bean seedlings. |
