摘要
为了解八大香型烤烟的力学特性、外观质量差异以及二者之间的关系,选取八大香型烤烟典型烟区的C3F等级烤烟测量力学特性,并对烤烟外观质量进行评定打分,采用通径分析对烤烟力学特性与外观质量的关系进行分析。结果表明,八大香型烤烟以福建三明烟区烤烟柔软性最好,柔韧性较强,但黏附力较差;许昌烟区烤烟柔韧性与黏附力较强,但柔软性较差;重庆产区与遵义产区烤烟的柔软性较好,但重庆产区烤烟柔韧性较差;其他产区烟叶各力学指标表现适中。江川烟区烤烟的外观质量最好,遵义烟区、重庆烟区以及许昌烟区烤烟的外观质量次之,诸城烟区与牡丹江烟区烤烟的外观质量再次之,郴州烟区与三明烟区烤烟的外观质量较差。烤烟的穿透力对烤烟色度的直接通径系数达到-0.770,剪切力对烤烟颜色、成熟度的直接通径系数分别达到0.954、0.983,黏附力对烤烟油分的直接通径系数达到0.960,柔软度对烤烟叶片结构的直接通径系数达到0.936,拉力强度对烤烟颜色的直接通径系数达到-0.949。烤烟力学特性对外观质量有较大的影响,可以为烤烟质量客观评价提供依据。
In order to study the differences and relationship of mechanical properties and appearance quality in eight flavor types of flue-cured tobacco,C3F grade of flue-cured tobacco in eight flavor types was selected to measure the mechanical properties,and the appearance quality was evaluated and scored.Path analysis was used to analyze the relationship between mechanical properties and appearance quality of flue-cured tobacco.The results showed that the softness of flue-cured tobacco in Sanming region of Fujian Province was the best,and the flexibility was strong,but the adhesion was poor;the flexibility and adhesion of flue-cured tobacco in Xuchang were stronger,but the softness was poor;the softness of flue-cured tobacco in Chongqing and Zunyi production areas was better,but the flexibility of flue-cured tobacco in Chongqing production area was poor;the mechanical indexes of tobacco leaves in other production areas were moderate.The appearance quality of flue-cured tobacco in Jiangchuan was the best,followed by Zunyi,Chongqing and Xuchang,Zhucheng and Mudanjiang,Chenzhou and Sanming.The direct path coefficient of penetration to color of flue-cured tobacco was-0.770,the direct path coefficient of shear force to color and maturity of flue-cured tobacco was 0.954 and 0.983,the direct path coefficient of adhesion to oil content was 0.960,the direct path coefficient of softness to leaf structure was 0.936,and the direct path coefficient of tensile strength to color was-0.949.The mechanical properties of flue-cured tobacco have great influence on the appearance quality,which can provide the basis for objective evaluation of flue-cured tobacco quality.
