| 摘 要： | 精养虾池中，影响浮游植物丰度的主因子由大至小依次为磷酸盐〉氨氮〉铁〉亚硝酸氮〉盐度〉酸碱度〉硝酸氮〉温度〉锰〉溶解氮。肖游植物的Ｓｈａｎｎｏｎ－Ｗｅａｖｅｒ指数与水质的富营养程度密切相关，前期该指数普遍小于后期，主要随着水质富营养化程度增高。该指数降低；该的指数的大小还直接与虾的成活率呈负相关（Ｒ＝－８．８）。水中理化因子的含量与虾的成活率相关程度不高，但理化因子的变异系数与虾的成活率密切相关（Ｒ

| Abstract: | The main factors affecting the phytoplankton fecundity are nitrogen in NO3or NH4 , phosphorus in phosphate, manganese, etc in the shrimp ponds. The correlative co-efficiency between phytoplankton Skannan-weaver index and eutrophy is significant (R=0. 90 or so). This index is also related to the shrimp survival rate. The correlative co-efficiency between physicochemical factor and shrimp survival rate is not significant, but the varl able coefficient of physicochemical factors is highly ralated to shrimp survival rate. Through adding the photosynthetic bacterium and chloride dioxide (ClO2) to clean water body in pond, the occurrence of shrimp disease reduces. |
