摘 要:【目的】探索桑蚕一代杂交种成品卵质量检验新方法,提高成品卵质量检验的准确性、高效性及可操作性。【方法】分别采用直接计数蚁蚕法、称量计算蚁蚕法、直接计数良卵法,进行蚕种孵化率和良卵数调查,并比较3种方法的调查效率。【结果】采用称量法计算蚁蚕头数与直接计数蚁蚕头数的结果无显著性差异,采用直接计数良卵数与实际良卵孵化值误差达到极显著水平;在效率方面,直接计数良卵法耗时是直接计数蚁蚕法的56.75%,而称量计算蚁蚕法耗时仅是直接计数蚁蚕法的21.83%,节省约4/5的调查时间,工作效率极大提高。【结论】将称量计算蚁蚕法应用于良卵数和孵化率调查是可行的,且具有操作性好、省时、省工、效率高,准确性高等优点。[Objective]The present study was conduced to develop a new, accurate and efficient method for inspecting quality of silkworm F1 hybrids egg products. [Method]Hatching rate and number of good eggs were determined by direct counting of newly-hatched larva, weighing newly-hatched larva and direct counting of good eggs. These three methods were compared with each other for their efficiency. [Result]There was no significant difference between weighing and direct counting on newly-hatched larva, while significant difference occurred between the number of good eggs using direct counting method and the actual number of newly-hatched larva. For efficiency of the method, the time-consuming for direct counting of good eggs was 56.75% of direct counting of newly-hatched larva, while that of weighing method was only 21.83% of direct counting of newly-hatched larva, indicating that approximately 4/5 investigation time was saved so to enhance the work efficiency enormously. [Conclusion]Weighing newly-hatched larva method was found time and labor-saving, highly effective and accurate, and easy to be operated, hence it is feasible to apply weighing method to investigate the number of good eggs and hatching rate.
