测定了10％苄嘧磺隆可湿性粉剂对固氮鱼腥藻的生长效应以及光合色素的影响，探究其生态毒性。结果表明：低质量浓度处理下（＜0.1 mg/L），苄嘧磺隆刺激固氮鱼腥藻的生长，使其干重和细胞数呈现稳步增长趋势，对光合色素含量影响不显著。高质量浓度苄嘧磺隆（1 mg/L 和10 mg/L）显著抑制固氮鱼腥藻的生长，对其生长速率、干重、细胞数及光合色素等产生明显的影响。
測定瞭10％芐嘧磺隆可濕性粉劑對固氮魚腥藻的生長效應以及光閤色素的影響，探究其生態毒性。結果錶明：低質量濃度處理下（＜0.1 mg/L），芐嘧磺隆刺激固氮魚腥藻的生長，使其榦重和細胞數呈現穩步增長趨勢，對光閤色素含量影響不顯著。高質量濃度芐嘧磺隆（1 mg/L 和10 mg/L）顯著抑製固氮魚腥藻的生長，對其生長速率、榦重、細胞數及光閤色素等產生明顯的影響。

Effects of 10% bensulfuron methyl WP on the growth and photosynthetic pigment of Anabaena azotica were determined to explore its ecological toxicity.The results indicated that under low concentration (<0.1 mg/L),bensulfuron methyl could stimulate the growth of Anabaena azotica,the dry weight and cell num-ber showed a steady growth trend,but there was no significant effect on the content of photosynthetic pigment. High concentration of bensulfuron methyl (1 mg/L and 10 mg/L)inhibited the growth of Anabaena azotica signifi-cantly,and they had a clear effect on the growth rate,dry weight,cell number and photosynthetic pigment.
