育珠池与鱼池主要理化因子昼夜变化规律比较研究

2003年7月16日至17日对淡水珍珠池与养鱼池水质进行对比分析,结果表明:珍珠池与鱼池的理化因子中水温和pH变化趋于一致,透明度鱼池高于珍珠池.溶氧含量的变化最大,其平均溶氧含量鱼池高于珍珠池,从垂直变化来看,珍珠池表、底层溶氧量相差在(3.56-5.26)mg/L之间,而鱼池无明显的垂直分布现象.主要营养盐中,N的含量珍珠池高于鱼池,而P的含量鱼池较珍珠池高.从垂直分布来看,珍珠池与鱼池底层均高于表层、中层.

Study on the Change Regulation of Main Physics and Chemistry Factor of Pearl Pond and Fish Pond in Day and Night

Analysis of the comparison between' freshwater -pead - pond and fish - pond on water condition has been made on July 16th and 17th,2003.It showed that the water temperature and the pH variety about the physics and chemistry factor of the pearl -pond and the fish- pond jump together,the fish pond's clarity was higher than the pearl - pond.The amount of dissolved oxygen in water las the deal biggest variety, the fish - pond's average dissolved oxygen perpendieulary had a deal higher level than the pearl - pond' s.see from perpendicular variety,pearl- pond form with the bottom' s annount of dissolved oxygen differing in the 3.56 - 5.62mgs/L from the surface, but fish - pond didn' t have the obviously distributes phenomenon.Main nourishment salt inside, the amount of N in the deal pearl - pond was higher than the fish - pond, but the P in the deal fish - pond was less than the pearl - pond. Distribute to see from the perpendicularity, the nourishment salt in the bottom was more than that in middle and surface.
