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℃ ,石蛙孵化开始出现畸形苗 ,32℃是其孵化的致死水温

摘  要:
It's suggested by the preliminary experiment,conducted by means of hatching seedlings of ranaspinosas in the gentle flow of groundwater,that the temperatures of water have a great effect on the ranaspinosa seedlings in rate of emergence;21-23℃ are the most suitable water temperatures for hatching;when the temperature is above 25℃,deformed seedlings begin emerging during the incubation;and that the water temperature of 32℃ is lethally high for hatching.
