摘要
采取常规采收、除芽采收(T1)和留芽采收(T2)3种采收方式,测定K326烤烟的农艺性状、化学指标、经济指标,分析采收方式对K326上部烟烘烤过程中挂灰程度的影响。结果表明:留芽采收烤后烟叶总糖、还原糖、淀粉含量、单叶质量、挂灰程度均比常规采收降低,其中淀粉含量和挂灰程度分别降低60.6%和59.7%;除芽和留芽采收处理烟叶的绿原酸、咖啡酸、莨菪亭含量较常规采收降低,留芽采收较常规采收分别降低9.4%、8.3%和9.1%。与常规采收相比,留芽采收能提升4%的上部烟均价。
In this study,3 harvesting methods including conventional(CK),bud removal(T1)and bud retention(T2)were used to collect upper leaves of flue-cured tobacco K326.The agronomic,chemical,and economic indicators of the upper leaves were meaured to investigate the effect of different harvesting methods on the degree of browning leaf during baking process.The results showed that the total sugar,reducing sugar,starch,dry leaf weight and degree of leaf browning of flue-cured tobacco leaves in bud retention treatment were all lower than those in conventional treatment,the decrease of starch content and browning leaves degree reaching 60.6%and 59.7%.However,chlorogenic acid,caffeic acid and scopolamine in leaves with bud removal and bud retention treatments were lower than those in conventional treatment,which in bud retention treatment were respectively 9.4%,8.3%and 9.1%lower compared to conventional treatment.In addition,bud retention harvesting could increase the average price of upper tobacco leaves by 4%.
