摘要: 【目的】为完善烤烟质量评价体系和制定烟草种植区划提供技术支撑。【方法】以湖南省烟区2005年烤烟样品为材料,运用专家咨询法、多元统计方法、模糊数学方法、地统计学分析等构建了烤烟外观质量量化评价体系,并进行外观质量评价指标间的关系和湖南烟区烤烟外观质量区域特征分析。【结果】烤烟外观质量评价指标间存在极显著的相关关系;不同等级烟叶外观质量分值是:X2F<B2F<C3F,差异极显著;不同品种烟叶外观质量分值不存在统计学上的差异;不同生态区域烟叶外观质量分值是:湘南烟区<湘中烟区<湘西北烟区,差异极显著;烟叶外观质量指数高值区域出现在湖南西部,向东逐渐递减,空间差异明显;进行评价的湖南X2F、C3F、B2F等级烤烟外观质量主要集中在3类烟和2类烟,1类烟较少,不同等级、不同生态区域烟叶外观质量类型差异明显。【结论】应用专家咨询法、因子分析和模糊数学方法建立的烟叶外观质量量化评价体系具有合理性,对某区域烟叶外观质量进行综合评价是可行的。

Abstract: 【Objective】Technological support was offered for perfecting the system of flue-cured tobacco quality evaluation and establishing regional assignment of tobacco planting by constructing the evaluating quantitatively system of appearance quality of flue-cured tobacco and being verified preliminarily. 【Method】The evaluating quantitatively system of appearance quality of flue-cured tobacco was constructed by adopting expert consultation, factor analysis, cluster analysis, fuzzy mathematics, statistical description, analysis of variance, analysis of correlation, geo-statistical analysis et al with flue-cured tobacco samples from tobacco-growing areas of Hunan in 2005, the correlation of evaluating indexes of appearance quality and region characteristic of appearance quality of flue-cured tobacco in Hunan were analyzed by that.【Result】There are extreme significance positive correlation between evaluating indexes of appearance quality. Evaluating indexes of appearance quality was clustered to 3 types: chroma, chromatic homogeneity, oil; mature, growth status, leaf structure, body; smooth or green-yellow. The sequence of the appearance quality score: X2F<B2F<C3F, and the score difference was extreme significance in different grades. There was not statistical difference of appearance quality score in different varieties. The sequence of the appearance quality score: Xiangnan<Xiangzhong<Xiangxibei, and the score difference was extreme significance in different ecological regions. The appearance quality index in spatial distribution reduced gradually from the high score area in west Hunan to the low score area in east Hunan, and the spatial difference of appearance quality index was distinctness. The styles of appearance quality of flue-cured tobacco in Hunan concentrate mainly on number three and number two, and less on number one. The difference of styles of appearance quality was distinctness in different grades and ecological regions.【Conclusion】The rationality of evaluating quantitatively system of appearance quality of flue-cured tobacco constructed by adopting expert consultation, factor analysis, fuzzy mathematics was verified, and that was doable to evaluate synthetically the region characteristic of appearance quality of flue-cured tobacco.
