摘要 采用无土栽培的方法研究了两种湿地植物石龙芮和酸模在生活污水中的生长特性及其对氮、磷的吸收能力。结果表明,试验期间,两种植物均生长良好,石龙芮、酸模的单株生物量(鲜重)分别由移植前的184、313g增至358、573 g。植物组织中氮、磷含量较高,石龙芮地上部分氮、磷含量可达24.69、4.97 g/kg(以干重计算),酸模地上部分氮、磷含量可达29.12、2.37 g/kg(以干重计算)。单株石龙芮地上部分对氮、磷的吸收量平均分别达到360.21、95.00 mg,单株酸模地上部分对氮、磷的吸收量平均分别达到882.20、77.96 mg。在适度的污染负荷下,两种植物对氮、磷吸收的平均贡献率分别为40.8%、52.5%。
