Abstract: Procambarus clarkii-rice model has good economic benefits. Aquaculture water of Procambarus clarkii must use wetland plants to effectively purify nitrogen and phosphorus. In this paper, referenced the phenotypic characteristics of the crops root system for the efficient absorption and utilization of nitrogen and phosphorus, and summarized the phenotypic plasticity, root structure and physiological function of wetland plants, as well as the research progress of removed nitrogen and phosphorus in water. It is suggested that adjusted the phenology of wetland plants, induced the roots phenotypic plasticity with efficiently absorption and utilization of nitrogen and phosphorus under the different concentrations, to suite the critical treatment period of Procambarus clarkii aquaculture water. and construct the artificial floating island by reasonable combination of species.

Key words: Procambarus clarkii, eutrophication, ecological purification, wetland plant, phenotypic plasticity, ecophysiological features
