不同调制方式和施氮量下烤烟和白肋烟糖含量差异分析
Effects of Different Nitrogen Application Rate and Curing Methods on Contents of Sugars in Flue-cured Tobacco and Burley Tobacco
摘要
Abstract
Field experiments with K326,Zhongyan 100,Dabai 1 and TN90 as materials were set up to ex-plore the reason for the differences of carbohydrate contents between flue-cured tobacco and burley tobac-co by investigating the changes of carbohydrate contents under the different conditions of nitrogen applica-tion rate and curing methods.Results showed that tobacco type had the most important influence on the contents of total sugars and reducing sugar,the second was curing methods,and the last was nitrogen ap-plication rate.The contents of total sugars and reducing sugar of K326 and Zhongyan 100 in air-curing condition showed a decreasing trend compared with flue-curing condition,but still at a higher level.Al-though the contents of total sugars and reducing sugar of burley tobacco in flue-curing had a certain rise, which was still at the low level.The ratios of reducing sugar and total sugars in both middle and upper leaves of Zhongyan 100 were approximately 0.95,and there was no significant difference among different curing methods.However, the significant difference was observed in both middle and upper leaves of TN90 among different curing methods in ratios of reducing sugar and total sugars, and the ratios were showed as flue-curing>flue-curing after air-curing>air-curing.关键词
