水稻对富营养化水体生态修复效应及其研究进展

水体富营养化是制约我国农业可持续发展的重要因素。水稻具有显著的水质净化能力,利用水稻对富营养化水体进行生态修复成为植物修复的一个重要的研究方向。通过文献调研,总结了水稻对不同富营养化水体(湖泊、水库、污水河道、养殖尾水、农田退水和生活污水)修复效率,综合分析了不同修复模式(浮床种稻、稻田湿地和稻鱼共作)的技术特点、适用范围和影响因素,归纳总结了水稻对富营养化水体修复的主要作用机制,并对下一步的研究提出了相关建议。

Advances in Restoration Effects of Rice Growing on Eutrophic Water

Eutrophication is an important factor limiting sustainable development of agriculture in China. Rice has significant capacity to purify eutrophic water. With in-situ and ex-situ remediation technologies, rice planting has great potential in restoration of eutrophic water in lakes, large reservoir, sewage river, fertile water from aquaculture pond, the irrigation return flow and domestic wastewater. With a summary of previous studies, We comprehensively compared the effects of rice planting on the restoration of eutrophic water and the removal efficiency of nutrients, and analyzed the technical characteristic and disadvantages in the application of three modes(floating-bed rice planting, paddy wetland and rice-fish co-culture).
