泥螺苗种消毒药物筛选及消毒效果

根据毒性试验结果，选取氯霉素（SC=47.55mg/L)，福尔马林（SC=13.47mg/L)，漂精片（SC=3.78mg/L)。敌百虫（SC=7.79mg/L)和高锰酸钾（SC=0.422mg/L)等5种药物，组合成20mg/L氯霉素 300mg/L福尔马林，5mg/L漂精片 20mg/L短短是虫，20mg/L氯霉素 20mg/L敌百虫，5mg/L漂精片 300mg/L福尔马林和10mg/L高锰酸钾5种溶液，进行泥螺苗种浸泡消毒试验，并对其消毒效果进行评价，结果显示，各种组合药液均能在短时间内明显降低泥螺苗种体表的细菌总量，但对不同菌属细菌的杀灭效果不同，根据细菌数量统计及细菌菌群鉴定分析，认为5mg/L漂精片 20mg/L敌百虫组合为泥螺苗种的最佳消毒药物。

Study on Selecting Disinfectants for Bullacta Exarta and their Disinfecting Effects

According to the result of toxicity test, several disinfectants were selected for the disinfection of larvae Bullacta exarata. The disinfecting effects of different solutions, including 20 mg/L Chloramphenicolum +300 mg/L Liqour formaldehyde, 5 mg/L Bleaching power +20 mg/L Trichlophonus, 20 mg/L Chloramphenicolum +20 mg/L Trichlophonus, 5 mg/L Bleaching power +300 mg/L Lipour formaldehyde and 10 mg/L Potassium Permanganate were examined and discussed in this paper. It was showed that all the solutions used had significant disinfecting effects, while the 5 mg/L Bleaching power +20 mg/L Trichlophonus solution was the most effective disinfectant according to the bacteriological counts and identification.
