| 摘 要： | 赤泥作化学改良剂能有效降低土壤重金属对通菜生长的抑制作用,增加植株生物量,显著增加通菜地上部鲜重与干重.重金属污染的土壤经过赤泥处理还能使通菜中Cd的含量显著降低,表明赤泥可以有效减少通菜对重金属Cd的吸收.经赤泥处理后,重金属污染土壤的pH值显著上升,从而降低土壤中重金属含量.

| Abstract: | The paper investigated the effect of red mud on the heavy metal contaminated soil.The result indicated that the sole cadmium treatment with relative lower concentration(20 mg/kg) could promote the growth of Ipomoea aquatica.In the soil polluted by several heavy metal elements,the growth of Ipomoea aquatica was inhibited,and the content of Cd in vegetables were also larger than the control.The denser the cadmium was in the soil,the worse the plant grew,the lower the plant biomass was and the higher the cadmi... |
