对狐尾藻进行了加氧与不加氧对照处理,比较了它们在不同镉离子浓度水体中的生长状况。通过检测水体中的镉离子浓度值,研究了狐尾藻对镉离子的吸附能力及其对镉离子的富集系数,采用WinRHIZO软件对狐尾藻的根系生长进行了分析,结果表明:在2种处理方式下,狐尾藻在镉离子浓度小于5 mg/L时均能正常生长,且加氧处理可显著提高其对镉离子的吸附能力;狐尾藻在镉离子浓度大于10 mg/L时均受镉离子胁迫作用导致叶片枯萎,且加氧处理可显著加快其对镉离子的吸附速度;狐尾藻在不同镉离子浓度下其最高富集系数为试验设置的20 mg/L,而加氧处理可将最高富集系数提高13.35%。由此可知,加氧处理可促进狐尾藻根系生长...

Compared the Myriophyllum growth in the water containing different concentrations of cadmium by the oxygen and without oxygen treatment,studied the Myriophyllum adsorption capacity of cadmium and its bioaccumulation factor of cadmium,analyzed the root growth of Myriophyllum by WinRHIZO software. The results showed that within the two treatments the Myriophyllum could grow normally in cadmium concentration below 5 mg / L,the adsorption of cadmium was significantly increased with the increase of oxygen treatment. Leaf blight of Myriophyllum under cadmium stress when the concentration was more th...
