云南KRK26品种不同采收成熟度对烟叶质量的影响
Effects of Different Harvesting Maturity Degrees on Yield and Quality of Flue-cured Tobacco KRK26 in Yunnan Province
摘要
Abstract
[Objective] To effectively enhance the production technology level and leaf quality in winter and spring of flue-cured tobacco KRK26 in Dehong Tobacco Area of Yunnan Province.[Method] We researched the effects of different harvesting maturity degrees on the dry weight-fresh weight ratio and leaf-stalk ratio of tobacco leaves,appearance quality of flue-cured tobacco leaves,quality and yield of flue-cured tobacco,and chemical components of tobacco leaves.[Result] Appropriate maturity standard in lower leaves was full white and shiny main veins,1/2 white branch vein and obviously yellow on leaf surface.The mature standard indice of the middle leaves were full white and shiny main veins,2/3 white branch vein,uniformly yellow on leaf surface,dry leaf tips and leaves edge,and pale yellow leaf auricles.The maturity standard of the upper leaves were full white and shiny main veins,2/3 white branch vein,yellow bubble on leaf surface,markedly increased stem and leaf angles,dry leaf tips and leaves edge,pale yellow leaf auricles and a small amount of brown spot disease.[Conclusion] Different positions of tobacco leaves could be harvested and cured when achieving the maturity standard,which was helpful to enhance the yield and quality of flue-cured tobacco KRK26.The tobacco yield,output value,average price would reach 2 250.0 kg/hm2,62 700.0 yuan/hm2 and 27.8 yuan/kg,resoectivelv.关键词
