| 摘 要： | 采用营养液培养,研究了凤眼莲、空心莲子草、碎米莎草、丁香蓼对水体中氮、磷的吸收.结果表明,凤眼莲对铵态氮、硝态氮和磷的累积吸收量高于空心莲子草,其次是碎米莎草,丁香蓼最小,这与植株生物量呈显著正相关,表明植物对氮、磷的吸收受植物生物量的影响.相比较而言,风眼莲最适宜用于人工湿地去除氮、磷营养元素.

| Abstract: | A solution culture experiment was conducted to study the ability of four aquatic plants,Eichhornia crassipes,Al-ternanthera philoxeroides,Cyperus iria and Ludwigia hyssopifolia,in absorbing nitrogen (N) and phosphorus (P). The results showed that the amount of NH_4~+-N,NO_3~--N and P absorbed by four aquatic plants followed the order: Eichhornia crassipes > Altemanthera philoxeroides > Cyperus iria > Ludwigia hyssopifolia,which were correlated positively to their fresh weight of plant. Therefore,Eichhornia crassipes was more suitable for constructed wetland for the removal of N and P. |
