摘要: 对精养鱼池的水体及淤泥进行多次采样,用统计学分析处理,结果表明:硝化类细菌总体上与各主要理化因子的相关性较强(R>0.60),其中氨化菌主要与溶氧相关程度较高;反硝化菌主要与有效磷相关程度较高;亚硝化菌主要与氨氮负相关程度较高;硝化菌主要与亚硝酸盐相关程度较高.硝化类细菌与异养菌之间的相关性则更强,如反硝化菌与厌养菌(R=0.944,P=0.001)、反硝化菌和好氧异养菌(R=0.32,P=0.003)皆显著正相关,亚硝化菌和厌氧异养菌(R=-0.76,P=0.009)显著负相关;而在硝化类细菌之间的相关程度却较弱(R＜0.60),表明池塘硝化类细菌对水质具有一定的调控作用,但相互之间的依赖性不强,各自相对独立地发挥作用.Abstract: A good number of samplings were taken from pond water and pond botton soil The statistic analytic results show that the biomass of the nitrite bacteria(including ammonifying bacteria, nitrobacteria, nitrifying bacteria and denitrifying bacteria)in general are closely correlated with various physicochemical factors(R0.06):Ammonifying bacteria are mainly correlated with dissolved oxygen; denitrifying bacteria are reverselly correlated with available phosphorus; nitrobacteria are reversely correlated with ammoniac nitrogen; Nitrifying bacteria are closely correlated with nitrites The bacteria are more closely correlated with heterotrophic bacteria:aerobic heterotrophic bacteria are significantly correlated with anaerobic heterotrophic bacteria; Denitrifying bacteria are significantly correlated with anaerobic heterotrophic bacteria; Denitrifying bacteria are significantly with aerobic heterotrophic bacteria Nitrobacteria are significantly reversed correlated with anaerobic heterotrophic bacteria But the proportion is quite weak among all the nitrite bacteria(R0.60)which indicates that the nitrite bacteria has a somewhat regulating function in water quality and there is no interdependant relation, each plays a role in its own.
