烤烟标准修订等级转化分析

Analysis on Transition of Revised Standard of Flue-cured Tobacco Grading

摘要: 为了证明烤烟标准修订稿在分级操作上的科学性和实用性，依据中国烟叶公司提出的烤烟标准修订稿（24级）文字描述制定了等级转换方法，通过转换前后的等级数量和部位对比统计，主收相邻等级加权得分方差分析对烤烟标准修订稿进行了等级转换分析。结果表明，转换后的等级包容了现行国标的所有38个等级，转换后等级数量减少为24个级，等级部位清晰，主收等级级差明显，操作性强，易掌握。因此，作者认为修订稿的烤烟标准具备先进性、科学性和可操作性。

Abstract: In order to verify the applicability and scientificity of revised standard of flue-cured tobacco grading system, a strategy of grade transition based on the text description in revised standard of flue-cured tobacco was designed, and the number and stalk position of grades were counted before and after transition. The weighted scores of adjacent grades were analyzed with one-way ANOVA. The result indicated that 38 grades were totally transferable to 24 grades of revised standard. The stalk position of grades and grade differences between adjacent grades exhibited more significant than before transition. The revised standard is practicable and easy to learn. Consequently, the revised standard of flue-cured tobacco was applicable, scientific and basically feasible.
