| 摘 要： | 研究了凤眼莲种植水抽滤液、不同部位的活体凤眼莲和干体凤眼莲的甲醇和丙酮提取物对铜绿微囊藻的化感抑制作用。结果表明：凤眼莲种植水抽滤液及不同部位的提取液均对铜绿微囊藻产生一定的化感抑制作用，并降低了稳定期的铜绿微囊藻产量。10%、50%、100%种植水抽滤液对铜绿微囊藻的抑制率分别81.06%、89.23%和89.78%。凤眼莲不同部位的甲醇和丙酮提取液对铜绿微囊藻的抑制强度不同，其中以根部的甲醇提取液效果最佳。由此得出：凤眼莲作为杀藻剂的材料具有一定的应用前景。 |

| Abstract: | Study was made on the allelopathic effect on Microcystis aeruginosa caused by filtered culturing water and extracts from different parts of Eichhornia Rrassipes. The result showed that filtered culturing water and extracts from different parts of Eichhornia Rrassipes had inhibition to Microcystis aeruginosa and reduced algal yield in stabilization period.When the concerntration of filtered culturing water was 10%, 50%, 100%, the inhibition rate was 81.06%, 89.23%and 89.78% respectively. The methanol and acetone extract of different part of Eichhornia Rrassipes inhibited Microcystis aeruginosa to various extent, of which the methanol abstract of Eichhornia Rrassipes root had the greatest inhibition. It was indicated Eichhornia Rrassipes.was one potential algaecide in the future. |
