家蚕一代杂交种成品卵(散卵)良卵率检验允许极差研究

家蚕一代杂交种成品卵(散卵)良卵率检验标准明确规定了良卵数或不良卵粒数平均值的计算方法,但其检验误差的允许值未做规定,因而无法评判检验结果的可靠性。以极差值估计检验误差,分析了影响成品卵良卵率检验误差的各种因素,提出了成品卵检查中良卵率的允许极差标准,以此作为衡量和控制蚕卵检验质量的指标,并通过对江苏省近几年成品卵检验的原始数据的统计分析加以验证。

Study on the Acceptable Range of Good Eggs Percentage of Product Eggs of Silkworm Hybrid

In "the testing rules for F1 hybrid eggs of silkworm",the method of counting the average number of good eggs and bad eggs was prescribed definitely.But the acceptable value of inspection error wasn't mentioned,which resulted in judging the reliability of inspection results hardly.In this paper,we estimated inspection error by range value,and analyzed the factors influencing the inspection error of good eggs percentage.At the same time,we established the acceptable range standard for inspecting good eggs percentage,and considered the standard as another index for scaling and controlling inspection quality of silkworm eggs.It was testified by the statistic analysis of original data from Jiangsu Province in recent years.
