摘　　要：[目的]探讨泥鳅养殖池塘水面浮植水蕹菜的最佳浮植面积比例。[方法]通过模拟高密度泥鳅养殖池塘中水面浮植不同面积比例的水蕹菜,研究了不同水面浮植面积(0、15%、20%和25%)对养殖水体中总氮、总磷的调控效果以及对泥鳅单位产量的影响。[结果]池塘水面浮植水蕹菜养殖泥鳅的最佳浮植面积比例为20%,面积比例过高或过低都会导致养殖效果逐渐降低。[结论]通过建立合理的水面浮植面积比例来调控泥鳅高密度池塘养殖模式所引起的水质恶化,可达到很好的水质调控效果和可观的经济效益。[ Objective ] The aim was to explore the optimal floating cultivation area proportion of Ipomoea aquatica for the culture of Misgurnus anguillcaudatus. [Method] The regulation effect of different floating cultivation area proportions of I. aquatica （0, 15%, 20% and 25% ） for the culture of M. anguillcaudatus on total nitrogen and total phosphorus as well as the effect on the yield per unit of M. anguiUcaudatus was studied. [ Result] The optimal floating cultivation area proportion of I. aquatica for the culture of M. anguillcaudatus was 20%, and too high or too low floating cultivation area proportion all caused the decrease of culture effect. [ Conclusion] The water quality deterioration caused by high-density pond culture model is regulated by establishing reasonable floating cultivation area proportion, and it reaches good water quality regulation effect and economic benefit.
