| 摘 要： | 该文提出了种子质量标准的试验与分析方法，研究了试验观测值的数学模型，引进了“本真值”新概念，创立了以本真值为标准尺度的标准值计算方法。品种纯度标准值（ＣＰＳＶ）等于纯度试验平均值（Ｘｃ）与纯度试验标准误（Ｓｅｃ）之差，即ＣＰＳＶ＝Ｘｃ－Ｓｅｃ；种子净度标准值（ＳＰＳＶ）等于净度试验平均值（Ｘｓ）ｇｎ ｕｑｖｈｙａ ｙａｃｗｓｆｕｗｙｋｇｄ（Ｓｅｓ）之差，ＳＰＳＶ＝Ｘｓ－Ｓｅｓ；发芽率标准值（ＧＰＳ

| Abstract: | Methods of experiment and analysis of seed quality standard were produced, And studies on mathematical model of observed value were done. A new concept of " Native Value" was introduced. The calculating method of standard value was originated with native value being standard scale. Cultivar purity standard value (CPSV) equals experimental means of cultivar purity (Xc) minus standard erro (Sec), i. e. CPSV=Xc -Sect Seed purity standard value (SPSV)equals experimental means of seed puity (Xs)minus standard erro(Ses). i. e. SPSV = Xs -Ses;Germination percentage standard value (GPSV) equals experimental means of germination percentage (Xg) minus standard erro (Seg). i, e. GPSV = Xg -Seg; Moisture content standard value (MCSV) equals experimental means of moisture content (Xm) plus standard erro (Sem). i. e. MCSV = Xmm Sem. |
