1 种子纯度检验的迫切性我国所有作物种子的分级标准都是以纯度发芽率和净度三项标准作为定级依据的,其中以品种纯度作为定级的主要依据。如凡净度,发芽率两项中的一项比品种纯度级别低一级;两项其中无论一项或两项高于品种纯度级别的都按品种纯度等级定级。 1, the urgency of seed purity test Grading standards for all crops in China are based on the purity of germination rate and clarity of the three criteria as the basis for grading, of which the purity of the variety as the main basis for grading. Where the clarity, the germination rate of two varieties of a lower than the purity level of one; two of which one or two of which are higher than the purity level of species purity grade rating.
