摘要: 利用2005年度全國煙葉工商交接等級質(zhì)量監(jiān)督檢查資料對全國煙葉等級質(zhì)量進(jìn)行了分析,。結(jié)果表明，全國煙葉工商交接等級合格率在不同產(chǎn)煙省份間存在顯著差異,，變幅為44.9％~71.5％,。一般需求量大、質(zhì)量好的煙葉等級合格率較低,。除經(jīng)營管理方面的原因外,，對等級質(zhì)量進(jìn)行分析顯示，混部位,、混顏色,、混等級是合格率不高的主要問題。在原等級中混低的比例遠(yuǎn)遠(yuǎn)高于混高的比例,；上等煙葉混低的比例遠(yuǎn)遠(yuǎn)大于中,、下等煙葉混低的比例；中部煙葉混低的比例大于上部和下部煙葉混低的比例,。同時,，提出了提高煙葉等級質(zhì)量的關(guān)鍵在于誠信經(jīng)營、加強(qiáng)監(jiān)督和提高分級水平,。Abstract: The grade quality of tobacco leaves was analyzed using the data from national supervision of tobacco leaf grading quality during industry commerce handover in 2005. The results showed that there was a significant difference of national grade quality among different tobacco growing regions with a wide range of acceptable percentage from 44.9％ to 71.5％. The qualified rate was generally low for the leaf grade with large purchase quantities or fine quality. Beside the business and management factors, the main problem of the low qualified rate resulted from widespread existence of the mutual confusion of leaves among stalk positions, colors and grades. Analysis of the grading component indicated that the proportion of the low quality grade leaves was much higher than that of the high quality grade leaf mixed in original grade, while the ratio of the low quality grade leaf mixed in higher grade was much higher than that in middle and lower grades. In addition, the proportion of the low quality grade leaf mixed in the leaves from the middle portion of the plant was higher than that from the upper and lower positions. Some suggestions were made for improving grade quality of tobacco.
