| 摘 要： | 通过抽取４个组合５个性状（株高、茎径、茎数、锤度和丛重）不同容量的随机样本，比较其统计平均数和方差与２４０株所构成的总体平均数和方差的差异．以置信区间为基础，估算α＝５％，Ｋ＝１０％的水平下，至少需要１７０株实生苗的样本容量才能较准确地反映出所有性状的平均数和方差．

| Abstract: | Random samples with different capacities of 5 traits in 4 cross-combinations were taken out to make comparison of the averages and variances of samples with those of the population composed of 240 seedlings,and to indicate that at least 170 seedlings were used to reflect the population average and variances in all 5 investigated traits at the level of α=5%and K=10%on the basis of incredible regions. |
