摘要
对漂白粉的杀菌效果，对对虾毒性、对单胞藻和虾池水环境因子的影响进行了试验研究。池水有效氛浓度为０．３～０．５×１０（－６），不会对对虾和池内单胞藻造成危害，并可使氨氮含量降低，ＰＨ值增加，对溶解氧、化学耗氧量等无明显影响。治疗虾病时，先使用漂白粉，然后投喂药饵，可取得较好效果。
An experiment was conducted on the effect of using bleaching powder to kill bocterta,on itS toxicity to the prawn and on the influence on the unicellulsr alal as well as the factors of the waterenvironment Of the prawn POnd. The experimental result showed that if the effective chlorine concentration was at 0. 3￣ 0' 5 X 10-6,there was no harm to the prawn and unicellular alal in poal. On the contrary,this concentration could make the content of NHk-N reduced,the value of PH lucre￣ and there was no evident influence on COD and DO. When treated Prawns for their disease,first spreading bleaching POwder,then feeding medicine PelletS could produce bettsr result.
