摘要
采用乙醇法测定了3种药剂对烟草苗床藻类叶绿素含量的影响。结果表明,随施药浓度的增大抑制率呈上升趋势。在试验浓度范围内,高锰酸钾、代森锰锌对两种藻类均有较好的抑制效果,浓度大于500mg/L时,抑制率均在80%以上,三氯化铁对颤藻的抑制效果较低。
The effects of three agricultural chemicals on chlorophyll content of algae on tobacco seedbed were tested by the ethanol method. The results showed that the inhibition rate gradually enhanced with the increase of chemical concentration. In the range of experimental concentrations, the two dominant kinds of algae were well inhibited by permanganate potassium and mancozeb. When the concentration was over 500 mg,/L, the inhibition rate was more than 80%. The inhibiting effect of ferric trichloride was lower on Oscillatoria.
