- 摘要:
- 以花叶芦竹、千屈菜、小叶蚊母、花叶杞柳和细叶水团花5种植物为试材，通过盆栽试验，研究其净污能力。结果表明：5种植物在污水中生长后其体内营养元素含量发生变化，花叶芦竹吸收Mg、Mn、Zn能力较强，污水处理后千屈菜叶片中Mg、Fe、Mn 3种元素增幅较大，圆头蚊母对Ca、Fe、Mg、Al、Na 5种元素均有较强的吸收能力，花叶杞柳对Al的吸收能力较强，细叶水团花则对N、Fe、Zn、Al 4种元素具有富集作用。植物对营养元素的吸收富集作用因种类而异，在工程实践中应当根据水质来筛选适当的人工湿地绿化植物种类。
- Abstract:
- Five kinds of wetland plants such as Arundo donax var.versicolor Stokes，Lythrum salicaria Linn.，Distylium buxifolium (Hance) Merr.var.rotundum H.T.Cheng，Salix integraThunb.‘Hakuro Nishiki’ and Adina rubella Hance were selected for this pot experiment to study their net sewage capacity.The results showed that the body content of nutrient elements of the five kinds of wetland plants had changed after the growth in the sewage.Arundo donax var.versicolor Stokes had a strong ability to absorb Mg,Mn,Zn.The Mg,Fe,Mn had a large increase in the Lythrum salicaria Linn.leaves after sewage treatment.Distylium buxifolium (Hance) Merr.var.rotundum H.T.Cheng had a strong ability to absorb Ca,Fe,Mg,Al,Na while Salix integra Thunb.‘Hakuro Nishiki’ had a strong ability to absorb Al，Adina rubella Hance had a strong ability to absorb N,Fe,Zn,Al.Because the nutrition elements absorption abilities depended on the type of plants，the selection on appropriate artificial wetland green plant species should be based on water quality in engineering practice.
