| 摘 要： | 在富营养化水体中，利用人工基质无土栽培水生经济净化水质的静态试验结果表明，在５月～１０月间，水蕹菜对ＴＮ、ＴＰ的去除率分别为８１．３２％和７１．３４％；在１１月～３月间，水芹菜对ＴＮ、ＴＰ的去除率分别为８２．７７％和９４．７７％。经重金属检测分析，水蕹舸和水芹菜茎叶部分的Ｃｕ、Ｃｄ、Ｐｂ和Ｚn含量均处于可食用范围内。结 果现场试验结果，轮种上述两种经济植物，每m＾２水面每年可自水中移除ＴＮ２０４．８

| Abstract: | Purification of Liwahe creek which belonged to a eutrophic water body was studied by means of soilless cultivation techniques on artificial substratum from may, 1992 to March, 1998. In the static purification test, the removal rate of TN and TP with Ipomoea aquatica were 81.32% and 71.34% from May to October, respectively. With Oenanthe javanica , the above removal rate were 82.77% and 94.77% from November to March, respectively. The heavy metal content (Cu, Cd, Pb, Zn) data revealed that the soilless cultivated economical plants were eatable. The contribution degrees of plant uptake for N and P varied with economical plant iomass productivity and the pattern of vegatation and management in the field. |
