摘要
以铜绿微囊藻为研究对象,将微囊藻水华池塘分隔成数块小区进行控藻剂药效测试,通过测定藻蓝蛋白评价不同控藻剂对蓝藻的控制水平。结果表明,几种控藻剂对蓝藻防效效果有差异,其中复合处理组4与小球藻组合在实验第1,3,7,12,15天处理后的藻蓝蛋白含量和浊度值显著低于对照组,且DO显著高于对照组。这表明该控藻剂与小球藻联合对蓝藻的防治效果较好,且对水体的DO影响不大,克服了目前主流控藻剂使用后容易造成DO骤降带来的生态问题。
We selected microcystis aeruginosa as the research object,which was a dominant species of common cyanobacteria in water.The microcystis bloom pond was divided into several blocks.To evaluate the control effect of different algaecides on cyanobacteria,the phycocyanin in the body of cyanobacteria was detected.The several algaecides showed that it had different control effects on cyanobacteria,on 1,3,7,12 and 15 days,phycocyanin value and turbidity value of algaecides with chlorella vulgaris were significantly lower than that of control group,and its dissolved oxygen were significantly higher than that of control group.Algaecide with chlorella vulgaris can significantly inhibit the secondary recurrence of cyanobacteria.These results indicated that the algaecides with chlorella vulgaris had better control effect on cyanobacteria,and had no effect on dissolved oxygen in water.It overcame the ecological problems caused by the sudden drop of dissolved oxygen after the use of the current mainstream algaecides.
