摘 要 ：通过10种中草药水提液对铜绿微囊藻抑制效应的实验，筛选出五倍子具有较强的抑藻效果。结果显示：五倍子水提液抑制铜绿微囊藻的最大比生长率为-0.834 d^-1，对叶绿素a的抑制率显著，且持续时间长，低浓度组50 mg·L^-1处理3 h抑制率超过50%，高浓度组500和1 000 mg·L^-1处理24 h后抑制率均超过90%。证明五倍子抑藻作用具迅速、持续稳定的特点，对治理水华的发生有较大的应用前景。

Abstract:Through the experiments of inhibitory effects of water extracts from 10 Chinese herbal medicines on Microcystis aeruginosa, Galla chinensis was selected with strong effect. The results showed: the maximum specific growth rate of inhibition on M.aeruginosa by water extract from G.chinensis was 0.834 d^-1, the inhibition on chlorophyll a was significant with long duration. After 3 h treatment by low concentration group of 50 mg·L^-1, the inhibition rate was higher than 50%. After 24 h treatment by high concentration groups of 500 and 1 000 mg·L^-1, the inhibition rate was higher than 90%. Algal inhibition of G.chinensis figured out the characters of rapidity, sustainability and stablity, which has a great prospect of application in controlling water bloom.
