- Seasonal Changes of Nitrogen and Phosphorus Content of Aquatic Plant (Zizania latifolia) and Mass Balance of Nitrogen and Phosphorus in the Water Culture System of Zizania latifolia
抄録
A recent development to control eutrophication is done by the ecological engineering, which involves using plants for water purification. A number of researches about a water purification system have been conducted and the nutrient removal efficiency has been evaluated. However, there are few studies about the mass balance of nutrient content and the amount of absorption by aquatic plants. In this study, an experiment in a water culture system inhibiting the nitrification and denitrification was conducted to evaluate nitrogen and phosphorus content of aquatic plant Zizania latifolia, which is beneficial for nutrient absorption and nutrient elimination from an enclosed system serving as food for migrating swans, and the amount of nitrogen and phosphorus absorption from May to December in 2002 (32 weeks).<BR>The results were as follows: Z. latifolia grew as time, and the maximum wet weight of a Z. latifolia was taken in September (562g) and the maximum dry weigh of a Z. latifolia was taken in October (78.5g). The Nitrogen and phosphorus content of a Z. latifolia was increased from May to October, and the maximum values taken were about 2080mg and about 400mg, respectively. Finally, the nitrogen and phosphorus mass balance of the content of Zizania latifolia and the amount of removal from the culture solution from May to October (except September) was evaluated as 70%-110%.
