【摘要】 养殖中国对虾（Penaeuschinensis）的试验塘，以防病养虾塘水质管理模式加以管理，养殖周期为87~159天，取得较好的经济效益。虾塘水的主要理化因子基本符合要求，NH3-Nt＜1mg/L，0．005mg/L≤NO2≤0．016mg/L，溶氧处于过饱和状态，CODMn＜12mg/L、池塘单位水柱毛产氧量约为7g/（m2·d），总耗氧量约为5~11g/（L·d），并借助增氧机补足池水所缺需氧量。更多还原

【Abstract】 The test ponds for culturing Chinese prawn (Penaeus chinensis ) were managed under the modl of water quality management for preventing prawn diseases. The culture periods were 87 -159 days and good economic benefits were obtained. The main physical-chemical factors were fit with prawn’s requirements, such as NH3- N＜1mg/L, CODMn＜12mg/L, 0.005mg/L＜ NO2-N＜0.016mg/L, O2% ＞100%. Gross oxygen daily productions and total oxygen consumptions of water column in each square meter of prawn ponds were about 7g/(m2·d). The lack contents of oxygen in prawn ponds were made up definciencies by aerators.更多还原
