摘　　要：介电分选是一种新型的种子分选方法,具有结构简单、适应性强、分选效果好和可按种子活力进行分级的特点。电导率是反映种子活力的一个重要指标,分选电压是影响介电分选效果的一个重要因素,为了探讨电导率与分选电压之间的关系,介绍了棉种介电分选的原理,并在不同的分选电压条件下对棉种电导率进行了测定,同一条件下重复测定5次,所得数据用DPS统计软件进行分析处理。结果表明,分选电压对棉种电导率有影响,且回归效果显著。Dielectric separation is one of the advanced methods to separate seed.The characteristics are simple structure,good adaptability reliable separating effect,and classifying seeds according to the vigor differences.Electrical conductivity is a important index reflecting seed vigor.Voltage is a key factor affecting separation effect.For discussing the relation between electrical conductivity and separation voltage,this article introduced the principle of seed dielectric separation,tested electrical conductivities under different separation voltage and repeated measurement 5 times.At the same time,the test data were processed by DPS.The results showed that separation voltage had influence upon electrical conductivity,and the regression effect significent.
