摘要: 虾稻模式具有良好经济效益,而养殖水体必须用湿地植物高效净化氮磷。借鉴了农作物高效吸收利用氮磷的根系表型特点,综述了湿地植物表型可塑性、根系结构、生理功能以及已有去除水体氮磷研究进展。提出了人工调整湿地植物物候期,不同环境条件诱导其具有高效吸收氮磷的根系表型可塑性,以便适用于小龙虾(Procambarus clarkii)养殖水体的关键处理时期,合理搭配物种组合构建人工浮岛。

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
