凤眼莲、槐叶萍、水花生对污水中氮磷的吸收能力分析

Absorbency of Eichhornia crassipes,Salvinia natans and Alternanthrra philoxeroides to Nitrogen and Phosphorus in Polluted Water

研究了3种漂浮植物凤眼莲、水花生、槐叶萍在污水中的生长特性及其对污水中氮、磷的吸收能力。结果表明:凤眼莲在污水中的生长状况较好,单位面积生物量最大,对氮、磷的吸收能力最强;水花生和槐叶萍次之。

This paper studied the growth properties of Eichhornia crassipes Solms, Salvinia natans （L.） All and Alternanthrra philoxeroides in the polluted water, and analyzed their absorbency to nitrogen and phosphorus. The results showed that Eichhornia crassipes grew better in the polluted water, and it had the maximum biomass per unit area and the strongest absorption ability to nitrogen and phosphorus; Eichhornia crassipes was followed by Salvinia natans and Alternanthrra philoxeroides.
