摘要

Under the premise of simulating the growth environment of algae in natural conditions,the responses of Microcystis aeruginosa to stress of Rabbosia japonica were studied.The results showed that the maximum specific growth rate of M.aeruginosa inhibited by water extract from R.japonica was-0.083 d-1,and the inhibition effects on the electrical conductivity and pH of M.aeruginosa solution were significant with long duration.When the concentration of water extract from R.japonica was low,the maximum inhibition rate of M.aeruginosa was lower than 20%.When the concentration was 500 or 1 000 mg/L,the inhibition rate was higher than 50%after 144 h.It was proved that the inhibition effect of high concentrations of R.japonica on M.aeruginosa was significant and stable,which can provide reference for the control of water bloom in aquaculture water.
