摘要
利用地下水微流水状态下孵化石蛙卵子 ,初步试验结果表明 :水温对石蛙卵子的出苗率影响很大 ,2 1～ 2 3℃是其最适宜的孵化水温 ,当水温高于 2 5℃ ,石蛙卵子开始出现畸形苗 ,3 2℃是其孵化的致死水温 .
It′s suggested by the preliminary experiment, conducted by means of hatching seedlings of rana spinosa in the gentle flow of groundwater, that the temperature of water has a great effect on the rana spinosa seedlings in rate of emergence; 21～23 ℃ is the most suitable water temperature for hatching; when the temperature goes above 25 ℃, deformed seedlings begin emerging during the incubation; and that a water temperature of 32 ℃ is lethally high for hatching.
