Effects of Different Leaf Length,Width and Single Leaf Weight on Tobacco Quality After Roasting in Guangyuan
In order to explore the appropriate leaf length,leaf width and leaf weight range of high-quality cured tobacco leaves in Guangyuan and provide data support for the production of high-quality flue-cured tobacco in Guangyuan,10 tobacco farmers with representative planting levels were selected to take 2 kg samples of X2F,C2F,C3F and B2F from 5 purchase lines in Jiangue County,Guangyuan City,Sichuan Prov-ince in 2021. The tobacco leaf quality was evaluated according to different leaf length width and single leaf weight. The results showed as fol-lows:with the increase of leaf length,the contents of total sugar and reducing sugar in X2F,B2F tobacco decreased,and the contents of nico-tine and potassium increased with the increase of C3F. The content of total sugar and reducing sugar increased gradually with the increase of leaf width. The content of total sugar in tobacco leaves of X2F and C3F grades increased with the increase of single leaf weight,while the con-tent of potassium decreased. The total appearance quality of X2F increased first and then decreased with the increase of leaf width and single leaf weight. With the increase of leaf length,the total appearance quality of C2F and C3F increased gradually,and the total appearance quality was ranked from high to low as>75 cm,>65-75 cm,>55-65 cm,≤55 cm.With the increase of leaf length,leaf width and single leaf weight,the sensory quality scores of C2F,C3F and B2F mainly showed the trend of first increase and then decrease.With the increase of leaf length and width,the scores of C2F and B2F were firstly increased and then decreased.The comprehensive quality of X2F tobacco leaves was better when the leaf length was controlled at>50-60 cm,leaf width at>15-19 cm and single leaf weight at>7-11 g. When the leaf length of C2F was>55-65 cm,the leaf width was>15-23 cm and the weight of single leaf was>9-13 g,the comprehensive quality of C2F tobacco was better. When the leaf length of C3F was>65-75 cm,the leaf width was>15-23 cm and the single leaf weight was>8-12 g,the comprehensive quali-ty of C3F tobacco was better. When the leaf length of B2F was controlled at>55-65 cm,the leaf width was controlled at>15-23 cm,and the single leaf weight was controlled at>9-15 g,the comprehensive quality of B2F tobacco was better.
