目前,国内外种子带菌检验中,试验样品容量标准悬殊颇大,并多属于经验数量,甚至不顾不同种子的单粒重,以规定的种子重量作为试验样品量的统一标准。由此往往不能准确地反映种子批的有关信息,给生产带来一定的经济损失。为此,作者研究出一种合理确定种子带菌检验试验样品容量的数理统计方法。具体方法是: 对种子批带菌率作抽样检验时的样品容量,可按下式计算
At present, the domestic and foreign seed germ tests, the test sample capacity standard is quite large, and mostly belong to the number of experience, even regardless of the single seed weight of different seeds, with the provisions of the seed weight as a unified standard test sample size. Which often can not accurately reflect the relevant information of the seed batch, to bring some economic losses. To this end, the authors developed a reasonable mathematical determination of seed carrying capacity of test samples of mathematical statistics. The specific method is: the seed batch rate of bacteria for sampling when the sample size can be calculated as follows
