工商交接备货烟叶等级质量分析

Analysis on Grade Quality of Leaf Tobacco in Business Stock for Sale

本文根据全国烟叶工商交接等级质量监督检查资料对商业备货烟叶等级质量问题进行了分析。结果表明,不同备货单位间等级质量有很大差异,而且商业企业备货的烟叶等级质量决定工商交接烟叶等级合格率的高低。等级质量问题分析表明,备货烟叶等级合格率不高的主要原因是存在混部位、混颜色、混等级等现象。在原等级中混低的比例远远高于混高的比例,调拨量大、价格较高的烟叶等级合格率较低,中部烟叶等级合格率显著低于上部和下部。本文对提高烟叶等级质量也提出了有关建议。

The stock-tobacco grade quality was analyzed using sampling data from supervision of grade quality of countrywide flue-cured tobaccos during business-deal period in 2005. The results indicated that the grade quality of stock-tobacco in a corporation governed the qualification rate of the leaf grade of the industry-commerce deal, although there was significant difference of the tobacco grade quality among various enterprises. Analysis of the component of the origin grades illustrated that a main problem of the low qualified rate of the stock-tobacco was a widespread existence of the mutual confusion of leaves among positions from the plant, among colors, and among grades. In origin grade, the proportion of the mixed low-quality-grade leaves was far higher than that of the high-quality-grade leaves mixed. Moreover, the eligible percentage of the tobacco grade was low for leaf grades with large purchase quantity or high price, while the qualification rate of leaves from the middle portion of the plant was quite lower than that of the tobacco from the upper and lower portion. Some suggestions were made for improving grade quality of tobacco.
