摘　　要：通过排除光抑制、营养限制因素试验,研究水杨梅对斜生栅藻和铜绿微囊藻生长的抑制作用以及对叶绿素a的影响,并考察水杨梅对水中氮磷的去除能力。结果表明:水杨梅持续释放化感物质,在高藻密度条件下,对两种藻类的抑制率可达60%以上,同时能有效地降低水中的总氮、总磷。在试验周期内,覆盖组对共培藻类斜生栅藻水中总氮、总磷去除率超过83%和35%,对共培藻类铜绿微囊藻水中总氮、总磷去除率达到60%、40%以上,表明水杨梅对藻类有较好的抑制作用,可促进富营养化水体的修复,可作为抑藻浮岛植物的选择之一。Inhibitory effect and influence on chlorophyll-a of Adina rubella on the growth of scenedesmus obliquus and microcystis aeruginosa were studied by eliminating the photo-inhibition, nutrient-limiting factor of the test, and the ability to remove nitrogen and phosphorus in water for Adina rubella＇s were investigated. Results showed that in the condition of high algae density, allelochemicals was continuous released from microcystis aeruginosa, and the inhibition rate of two species of algae could reach over 60%. Meanwhile, the nitrogen and phosphorus could be reduced in water. After 10 days, the removal rate of total nitrogen and total phosphorus in the Scenedesmus obliquus cover cocuhure system were 83% and 35% above individually, while in the microcystis aeruginosa cover eocuhure system were over 60% and 40%. The water red bayberry had a good inhibitory effect on algae, which could promote the restoration of eutrophic water.
