摘　　要：采用围隔实验法考察不同虾蟹共作稻渔系统对养殖尾水的净化效果。结果表明:稻田及分别投放小龙虾和河蟹等稻渔共作系统均对养殖尾水净化作用显著,且相互间基本无显著差异(P>0.05);稻渔系统对水体中氨氮、亚硝氮、TN和TP的最大去除率分别为67.48%、78.13%、37.97%和53.05%;养殖尾水中I Mn与悬浮物于1 d~2 d、氨氮于2 d~4 d、TN于4 d~8 d、TP于8 d~16 d后显著降至较低水平;混养小龙虾和河蟹未对稻田净化水体产生显著扰动影响。In this paper,the purification effects of different rice-fish farming systems on aquaculture wastewater were studied through enclosure experiments.Results showed that paddy field,rice-crayfish and rice-crab farming systems all had significant purification effects on aquaculture wastewater,and there was no significant difference among different systems(P>0.05).The maximum removal rates of ammonia nitrogen,nitrite nitrogen,TN and TP were 67.48%,78.13%,37.97%and 53.05%,respectively.I Mn and suspended solids in aquaculture wastewater were reduced to a minimum in 1~2 days,ammonia nitrogen was in 2~4 days,TN was in 4~8 days and TP was in 8~16 days.In addition,the co-culture of crayfish and crab in paddy fields had no significant disturbance on the purification of aquaculture wastewater.
