生石灰清塘是我国淡水养鱼业中一种传统的清塘方式 ,弄清其水质变化规律 ,对池塘水质控制及鱼苗的适时下塘 ,都有重要意义。据李永函等[1] 试验表明 ,生石灰清塘后 ,池水的化学成份和生物因子都同时发生着有规律的变化。此种规律在本试验条件下 (水温 2 6℃、池底轮虫冬卵量 2
Clear lime pond is one of the traditional methods of clear pond in freshwater fish farming in our country. It is of great significance to clarify the regularity of its water quality and to control the pond water quality and timely pond of fry. According to Li Yong et al [1] test showed that after the quick lime pond, the chemical composition of water and biological factors at the same time there are regular changes. This rule under the conditions of this experiment (water temperature 26 ℃, the amount of rotifers in the bottom of the pond 2
