摘要
In order to find out the differences in qualified rate of acquisition grade of C3F flue-cured tobacco, investigation and analysis were carried out on the tobacco leaves of B2F grade mixed into the C3F grade in tobacco stations of Changning City in 2009 and 2011. Results showed that C3F belonged to the first-grade tobac- co of middle leaves, which was easily confused with B2F. The average qualified rate of C3F was 72% in 2009; while that was 82% in 2011 after implementing pro- fessional grading and loose tobacco acquisition, which enhanced by 10%. Phenom- ena of mixed grade, mixed position and mixed color were significantly improved; and there were no mixed green or mixed impurity.
为了探寻C3F烤烟收购等级合格率差异性,2009和2011年对常宁市各烟草站(点)收购C3F烟叶中混入B2F等级情况进行了调查分析。结果表明,C3F属于中部烟叶的上等烟,在烟叶等级分级上易与B2F混淆。2009年C3F平均合格率为72%,2011年实行了专业化分级和散烟收购,C3F平均合格率为82%,比2009年提高10个百分点,混等级、混部位、混颜色等现象得到明显改善,无混青、混杂等现象。
