在一般情况下,人们为了控制蓝藻,通常采用使池水达到0.7ppm的硫酸铜全池泼洒,但由于硫酸铜对鱼类毒性较大,一般不宜使用。笔者在88年的7月份在一口1.2亩的池塘内试用塘泥全池泼洒来压制蓝藻过多繁殖,取得了很好效果。塘泥泼洒的具体方法是,当判断水体中蓝藻较多时,用罱子罱取塘泥3～4担,将塘泥稀释成泥浆全池均匀泼洒,隔3天后,再重复一次,经一周后观察 Under normal circumstances, people in order to control the cyanobacteria, usually used to reach 0.7ppm pool of copper sulfate Quanchiposa, but because of copper sulfate toxicity of fish, generally unfit for use.
