Abstract:
Nitrate-N,total-N,moisture content and nitrate reductase activity of five aquatic plants (Ceratophyllum demersum，Potamogeton maackianus，Zizania caduciflora，Trapa japonica，Vallisneria natans)，distributing widely in Yunnan Province，were measured and compared.The results showed the absorption and utilization of nitrogen ability of five aquatic plants existed difference.The Nitrate-N absorption and utilization ability of Nitrate-N by Potamogeton maackianus and Ceratophyllum demersum were higher among five aquatic plants.Absorption ability of Nitrate-N by Trapa japonica was high and the conversion ability was weak.Nitrogen of the environment could significantly increase nitrate-N transformation ability of Zizania caduciflora.Five aquatic plants could be reasonably applied to landscape design according to N utilization ability differences.
