为了研究水培植物对富营养化水体的净化能力，将空心菜（Gynura cusimbua）、木耳菜（Ipomoea aquatica Forsk）和空心莲子草（A lternanthera Philoxeroides）3种蔬菜用富营养化水体进行培养，定期监测水体中的总氮和总磷质量浓度情况．结果表明，水培植物木耳菜、空心菜和空心莲子草对富营养化水体中总氮去除率分别达81．80％、68．61％和63．56％；对总磷的去除率各为44．24％、60．03％和31．58％．对比3种水培蔬菜单位鲜重的总氮和总磷去除能力表明，木耳菜对总氮和总磷去除能力最强，分别为0．0031mg／（L ．g FW ）和0．0006 mg／（L ．g FW ），可作为富营养化水体净化优先选择的植物．

In order to investigate the purification capability of eutrophic water by aqua‐cultured plants ,3 kinds of terrestrial vegetables ,Gynura cusimbua , Ipomoea aquatica Forsk and Alternanthera Philoxeroides were cultured in an aqua‐cultured system .Total nitrogen and total phosphorus were detected regularly during the culture period of aquaculture in the eutrophic water .The results indicated that the removal rates of total nitrogen by the 3 hydroponic vegetables were 81 . 80% ,68 .61% and 63 .56% ,respectively ,and the removal rates of total phosphorus were 44 .24% ,60 .03% and 31 .58% , respectively .Compared the removal capability of total nitrogen and total phosphorus by per unit fresh weight of 3 aqua‐cultured plants .Ipomoea aquatica Forsk had the strongest capability to remove nitrogen and phosphorus ,which was 0 .0031 mg/(L .g FW) and 0 .0006 mg/( L .g FW) ,respectively ,and implied that it can be an optimal plant for remedying eutrophic w ater .
