摘　　要：[目的]为调节和改善养殖微生态环境平衡和合理用药提供科学依据。[方法]以分离自养殖水体的硝化细菌为试验材料,运用生态毒理学的方法,在实验室条件下研究常用杀菌剂二氧化氯、高锰酸钾、甲醛、硫酸铜与硫酸亚铁合剂对其生长的影响。[结果]0.1mg/L二氧化氯、0.6 mg/L高锰酸钾、20 mg/L甲醛、0.7 mg/L硫酸铜与硫酸亚铁(5∶2)合剂对硝化细菌生长的影响较小,同时对水体中的病原微生物有较好的防治效果。[结论]在水产养殖中,应选用适宜浓度的杀菌剂对水体进行消毒。[ Objective ] The research aimed to provide scientific basis for adjusting and improving the balance of aquaculture micro-ecosystem and the reasonable application of drugs. [ Method] Using nitrifying bacteria isolated from aquaculture water as test materials, the effects of common bactericides C102, KMnO4, formaldehyde, the mixture of copper sulfate and ferrous sulfate bythe ratio of 5：2 on the growth of nitrif ying bacteria under the laboratory conditions were studied by the ecotoxicology method. [ Result] 0.1 mg/L C102, 0.6 mg/L KMn04, 20 mg/L formaldehyde, 0.7 mg/L mixture of copper sulfate and ferrous sulfate by the ratio of 5：2 had small effects on the growth of nitrifying bacteria and better control effects on aquatic pathogenic microorganism in water body. [ Conclusion] In the aquiculture ,suitable concentration of bactericides should be used to disinfect the water body.
