摘　　要：[目的]为了研究芦苇、红蓼、穗状狐尾藻和香蒲4种水生植物水浸提液对水华微囊藻生长的抑制效应。[方法]培养水华微囊藻细胞,制备4种水生植物的水浸提液,处理后通过藻细胞密度的测定计算抑制率。[结果]芦苇、红蓼、穗状狐尾藻和香蒲水浸提液对水华微囊藻的生长都表现出一定的抑制作用,其中芦苇的抑制效果最明显。[结论]利用水生植物分泌的化感物质抑制水华微囊藻生长是一种有效的控藻方式。[Objective] The research aimed to investigate the inhibition of four aquatic plants such as Phragmites communis,Polygonum orientale,Myriophyllum spicatum and Typha orientalis on the growth of Microcystis flosaquae by adding plant extracts.[Method] M.flosaquae cells were cultivated and the water extraction of four aquatic plants were prepared.The inhibitory rate was calculated by measuring intensity of algal cell.[Result] All these plants extracts showed certain inhibitory effects on the growth of M.flosaquae,and P.communis showed the most distinct inhibitory effects.[Conclusion] It was an effective method to inhibit the growth of M.flosaquae by using aquatic plants allelochemicals.
