| 摘 要： | 选取大聚藻、香菇草、鸢尾、黄菖蒲、金鱼藻和黑藻等6种水生植物,在静水条件下比较水质氮、磷净化能力.结果显示:(1)大聚藻和香菇草具有较好的生物量增长,鸢尾和黄菖蒲能保持正常生长且生物量有所增长,金鱼藻基本停止生长,黑藻出现部分腐烂现象;(2)6种水生植物总氮(TN)、总磷(TP)平均净化率存在较大差异,与无水生植物的空白对照相比,大聚藻、香菇草、鸢尾、黄菖蒲、金鱼藻和黑藻的TN净化增效作用分别为45.7%,39.6%,18.7%.16.4%,6.1%和-4.1%,TP净化增效作用分别为31.1%,30.1%,16.7%,9.9%,3.3%和-2.0%;(3)大聚藻、香菇草可以作为优选水生植物在冬季低温条件下应用于各种生态净水工程.

| Abstract: | Mean purification ability of nitrogen(N) and phosphorus(P) were investigated by using six aquatic macrophytes(Myriophyllum aquaticum,Hydrocotyle vulgaris,Iris ptectorum,Iris pseudacorus,Ceratophyllum demersum,Hydrilla verticillata) in the condition of static water.The results showed that:(1)For these six aquatic macrophytes,both Myriophyllum aquaticum and Hydrocotyle vulgaris showed relatively large increase in biomass;Iris ptectorum and Iris pseudacorus were able to keep growing at normal speed with the bi... |
