摘  要:
研究了家蚕卵产后经过 1~ 7d、10~ 2 0d解除滞育的孵化条件。蚕卵产下后在 2 5℃保护 1~ 7d的未完全滞育卵 ,用 1 0 75kg/L盐酸 ,4 6℃液温分别浸渍 5、10、2 0、2 5、4 0、4 5、5 0、70min ,实用孵化率可以达到 90 %左右。当蚕卵产下后在 2 5℃保护经过 10~ 2 0d时 ,用高温冲击加浸酸的方法可以解除其滞育 ,实用孵化率可达 90 %左右。

摘  要:
The eggs stored at 25 ℃ for 1-7 days after oviposition were treated by hydrochloric acid whose specific gravity is 1 075 for 5,10,20,25,40,45,50,70 min respectively at 46 1 ℃,the practical hatching rate still achieved 90% or above.After storage at 5 ℃ for 10-20 days,the deep diapaused eggs were shocked by hot air at 38-39 ℃ and then treated by hydrochloric acid,the hatching rate was also above 90%.
