浅谈棉花颜色级与品级的关系

Research on Relationship Between Cotton Color Grade and Cotton Grade

根据三年全国仪器化公证检验数据,统计了品级指标在颜色图上的分布,分析了棉花颜色级和品级的关系,二者的关系是:既有基本的共同点又有评判内容方法上的区别,基本的共同点是均反映了棉花质量,而且关系是相辅相成,不是根本上的对立的分级体系;区别就是表现了棉花质量评判内容及方法的不同。最后通过分析二者的关系得出结论:颜色图划分基本方向是符合人眼观察棉花颜色的。

According to the cotton official classification data in the past three years, we summarized the distribution of cotton grade index in cotton color grade chart. In the same time, the relationship between cotton color grade and cotton grade were analysed. The result is, cotton color grade and cotton grade have both similarities and differences. They both reflect the cotton quality, and they are complementary. The difference between the two systems is the quality evaluation content and method. In a word, the line direction in the cotton color grade chart accords with the human eye observation of cotton color.
