摘　　要：[目的]为筛选能够有效防治烟草漂浮育苗系统有害藻类的药剂。[方法]采用叶绿素含量测定法,测定了10种药剂对小球藻和颤藻的抑制效果及其最佳使用质量浓度。[结果]硫酸铜、高锰酸钾、70%甲基硫菌灵WP和硫酸亚铁对小球藻有良好抑制效果,抑制率分别达92.4%、84.3%、83.3%、81.3%;800 mg/L高锰酸钾对颤藻防效最好,达91.3%,500 mg/L的硫酸铜和700 mg/L 70%甲基硫菌灵WP防效也均在75%以上。[结论]高锰酸钾、硫酸铜和70%甲基硫菌灵WP可作为有效药剂对漂浮育苗系统小球藻和颤藻进行防治。[Aims]This study aims to screen out the chemicals for controlling that effectively harmful algae in the floating seedling system of tobacco.[Methods]The chlorophyll content method was used to determine the inhibitory effects and optimal concentration of 10 algicides on Chlorella and Oscillatoriales.[Results]The results indicated that copper sulfate,potassium permanganate,thiophanate-methyl 70%WP and ferrous sulfate showed good inhibitory effect on Chlorella and the inhibition rates were 92.4,84.3,83.3 and 81.32%,respectively.800 mg/L potassium permanganate showed the best control effect with 91.25%on Oscillatoriales,copper sulfate 500 mg/L and thiophanate-methyl 70%WP 700 mg/L also displayed control effect of above 75%.[Conclusions]Potassium permanganate,copper sulfate and thiophanate-methyl 70%WP can be used as effective algicides to control Chlorella and Oscillatoriales.
