Four substances including 2-methyl ethyl acetoacetate and barley straw extract distilled from bulrush as well as cetyl trimethyl ammonium bromide and isothiazo lintone were used for the comparison experiment in inhibiting the growth of Microcystis aeruginosa in various phases. Result showed that inputting chemicals in the lag phase has better effect than in the log phase, and adding in lag phase can effectively inhibit the algae growth. Although feeding allelopathic substance at log phase can lead to certain restraining effect, it cannot result in the effective inhibition of algae growth, which can be well achieved by feeding CTAB and isothiazo lintone below 10mgl/L during log phase.
