Abstract:: The purification of eutrophic water body was studied by means of soilless cultiation technique on artificial substratum. In lab test, three spices plants: Oenanthe decumbens, Lolium multiflorum and Ipomoea aquatica. Forsk grew well and the removing rates of TN, NH₄-N, NO₃-N, TP, PO₄-P were as high as 80%. The soilless cultivation technique on artificial substratum was studied in order to purify the eutrophic water body and to get considerable economic benefit at the same time. The application prospect of the means was discussed also.
Key words:: artificial substratum; soilless cultivation; eutrophication; economic plant
