摘要：Nutrient absorption and water purification by rice (Oryza sativa L.), canna (Canna indica L.), ree
d (Phragmites communis Trin.), and umbrella plant (Cyperus alternifolius L.), grown by the floating culture system, were compared under different pH conditions in natural water. The pH of the rooting zone in natural
water changed due to the increa in the CO2 concentration associated with root respiration, which was achieved by placing the roots in a plastic pot attached beneath the float to isolate the roots from the outside water. The absorption of nutrients (N and P) by umbrella plants was higher than that by the other plant species and was not inhibited by high pH values. In addition, the absorption of nutrients (N, P, K, and Fe) by umbrella plants incread with the application of a
slow-relea fertilizer to the basal part
