对沿黄地区主养鲤鱼和主养草鱼池塘溶解氧进行比较研究,结果是:草鱼池溶解氧条件优于鲤鱼池,但二者差异不显著;二池塘溶解氧都与水温和透明度关系密切;二池塘溶解氧昼夜和季节差异都显著,但垂直差异不显著。
The results showed that the dissolved oxygen in grass carp pond was better than carp pond, but the difference was insignificant. The dissolved oxygen in the two ponds was closely related to water temperature and transparency. Diurnal ponds diurnal and seasonal differences were significant, but the vertical difference was not significant.
