Regulating Effect of Biomass Ash Extract Liquor by Using a Foliage Spray Pattern on Quality of Middle and Upper Flue-cured Tobacco Leaves
摘要
Abstract
[Objective]The regulating effect of biomass ash extract liquor by using a foliage spray pattern on middle and upper flue-cured tobacco leaves was explored to provide a reference for rational utilization of flue-cured tobacco biomass burning waste in quality improvement of flue-cured tobacco.[Method]Yunyan 87 was used as the experimental material and a randomized block design was adopted.The leaves were sprayed with water once(CK1),twice(CK2)and three times(CK3)as controls.The leaves were sprayed with biomass ash extract liquor once(T1),twice(T2)and three times(T3)with an interval of 1 d,respectively.The leaf length,leaf width,relative chlorophyll content(SPAD value),chemical quality and neutral aroma substances of the initial cured tobacco leaves of 6 treatments were determined and compared.[Result]Spraying biomass ash extract liquor could increase leaf length,leaf width and SPAD value content of flue-cured tobacco,and improve chemical quality,and total sugar,reducing sugar and potassium content of the initial cured tobacco leaves,which reached production requirements of high-quality tobacco.According to the chemical composition usability evaluation index(CCUI)of the initial cured tobacco leaves,the score of middle and upper tobacco leaves of T3 reached 0.781 4 and 0.717 2 respectively.A total of 44 common components including linalool,geranylacetone,megastigmatrienone,and so on were detected from the initial cured tobacco leaves.Spraying biomass ash extract liquor had a significant effect on content of carotenoid degradation products,chlorophyll degradation products,Maillard reaction products,phenylalanine degradation products and cembratriendid alkyl degradation products in middle and upper tobacco leaves.Total content of aroma substances in middle and upper tobacco leaves of T3 reached 99.455 0 μg/g and 68.074 0 μg/g respectively.[Conclusion]Spraying biomass ash extract liquor on surface of tobacco leaves can improve agronomic characters of tobacco and increase chemical composition and aroma content of the initial cured tobacco leaves.The optimal foliage spraying pattern of biomass ash extract liquor for tobacco leaves includes three times on 7 d after topping with an interval of 1 d.关键词
