摘要： We tested the inhibitory effects of Cyperus alternifolius aquatic weed on growth of Microcystis aeruginosa and also identified some allelochemicals released by this aquatic plant. We found that the accumulation of allelochemicals in planting water solutions inhibited the growth of M. aeruginosa, especially after long cultivation time, which caused the accumulation of allelochemicals. The inhibitory rates of planting water solutions 5, 10 and 15 days after culture on M. aeruginosa were 29.3 %, 44.5 % and 59.0 %, respectively. Eleven compounds 8-fatty acids and 3-phenolics, with potential allelopathic activity, were identified in the extracts of planting water. These findings provide a basis for the use of artificial floating-bed plants to control the toxic cyanobacteria.
