【摘要】 通过不同除草剂质量浓度下鱼腥藻的生长状况比较及EC50的比较研究了新磺酰脲类除草剂单嘧磺隆对3种鱼腥藻的毒性作用,发现低剂量的单嘧磺隆(0.01～0.001mg/L)对藻类的生长无显著影响,而较高剂量(10～100mg/L)则会抑制藻类生长,3种鱼腥藻对单嘧磺隆的敏感性依次为:满江红鱼腥藻>固氮鱼腥藻>水华鱼腥藻。更多还原

【Abstract】 The effects of different concentrations of monosulfuron on growth of algae and value of EC50 were investigated. monosulfuron at low concentrations (0.01~0.001 mg/L) have no significant influence on the growth of three species of algae while at high concentrations (10~100 mg/L) monosulfuron inhibits all three algae’s growth. The algal sensitivity to monosulfuron shows following sequence: Anabaena azollae> Anabaena azotic > Anabaena flos-aquae.更多还原
