摘要
在沈阳市辽中区珍珠湖附近选取一条生态沟渠为研究对象,配置不同植物组合,建设生态沟渠.试验设计了稗草+芦苇、马唐+三棱草、野慈姑+眼子菜 3 种植物组合.结果表明,3 种植物组合对氮、磷元素均起到了吸附作用,总氮去除率分别为稗草+芦苇(87.68%)>马唐+三棱草(83.42%)>野慈姑+眼子菜(79.37%);总磷去除率分别为稗草+芦苇(85.24%)>马唐+三棱草(79.25%)>野慈姑+眼子菜(77.69%).
Abstract
An ecological ditch was selected as the research object near the Pearl Lake in Liaozhong District,Shenyang City,and different plant combinations were configured to construct an ecological ditch.Three plant combinations were designed for barnyardgrass+reed,crabgrass+cloverleaf,wild scorpion+waterweed,and the results showed that the three plant combinations had an adsorption effect on nitrogen and phosphorus,and the total nitrogen removal rate was different.Barnyardgrass+Phragmites australis(87.68%)>Crabgrass+Triangle grass(83.42%)>Ye Cigu+Pondweed(79.37%);the total phosphorus removal rate is Barnyardgrass+Phragmites australis(85.24%)>Crabgrass+Triangulum(79.25%)>Yescigu+pumpkins(77.69%).
