为揭示不同产区烤烟表面颜色光谱特性及差异,采用Color-Eye7000A分光光谱仪测定了国内不同产区C3F等级烟叶表面颜色光谱.结果表明:不同产区烟叶表面颜色的平均反射光谱呈现相似的曲线形态,在可见光波长范围,随着波长的增加,反射率逐渐增大,没有高峰和低峰;不同产区烟叶表面颜色在6个颜色波段的反射比率均表现为红色波段最高,其次是橙色波段、绿色波段、黄色波段、蓝色波段,紫色波段最低;不同产区烟叶表面颜色光谱差异的重要信息区主要集中在绿色波段(490～560nm)和红色波段(630～700nm).

　　In order to reveal characteristic and difference of color spectrum of flue-cured tobacco in different producing areas,the color spectrum measurement of C3F tobacco leaves in different producing areas were carried on the Color-Eye 7000A spectroradiometer.The results showed that the average reflective spectrum of tobacco leaves surface color appeared similar curve.In visible light range,reflectivity was continuously increasing with the increase of wavelength,and there were no high or low peak.Reflection ratio in the six color bands tobacco of...
