Abstract:Three cultural modes including Eleocharis dulcis planting water, aqueous extract of Eleocharis dulcis and Eleocharis dulcis co-culture with Microcystis aeruginos were studied to explore the effects of Microcystis aeruginosa growth. It is found that Eleocharis dulcis planting water, aqueous extract of Eleocharis dulcis and Eleocharis dulcis co-culture with Microcystis aeruginosa had inhibited the growth of Microcystis aeruginosa, and the inhibitory effects was caused by allelopahty. The inhibitory ratio of aqueous extract of Eleocharis dulcis with 100% concentration was 91.40%, and the ratio of co-culture mode was 86.83%. According to this research, it can be found that Eleocharis dulcis has a certain application prospect in the field of ecological algal inhibition as an emergent plant.
