Flue-cured Tobacco Leaf Quality Division And Evaluation In Bijie City Of Guizhou Province

This paper mainly in Bijie city eight flue-cured tobacco county as the research object, widely collect and refer to the relevant material, mainly produced in smoke area scientific and reasonable setting typicality and representative tobacco, soil sampling point, carry out the flue-cured tobacco quality characteristics and the ecological environment conditions of the relationship between fixed test research, to the appearance of the tobacco leaf quality, physical characteristics, chemical quality, sensory quality carries on the analysis, the appraisal, and according to different regional climate, soil and ecological characteristics of Bijie tobacco leaf quality division.From2009to2010, I colleced and triumed the datum in the Qixingguan, Qianxi, Jinsha, Dafang, Zhijin, Xianning, Narong, Hezhang of Bijie city by general investigating and sampling.The results show that tobacco nicotine content exceed to the appropriate content range, total sugar and reducing sugar content were more than the toplimited of the appropriate content range, total nitrogen and potassium content were less than the the appropriate content range, the content of chlorine ion were less than0.8%, the chemical ingredients content were more coordinated. Better tobacco quality with the completely tobacco odor types, better aroma quality, high odor quantity, less mixed gas, good taste, fine tobacco gas flexibility and better comfortable or comfortable aftertaste, better combustibility. In general, it has main characters with the golden appearance, lubrication, better maturity, high sugar content, low comparatively nicotine content, good aroma style, better aroma quality and taste. So we may divide the character of the tobacco quality into three types which are the fen-flavour type in the western, partial fen-flavour type in the central and medial fen-flavour type in the eastern of Bijie.This paper studies results will provide the a theoretical reference with the flue-cured tobacco planting regionalization, quality controlling,tobacco base construction, characteristics tobacco development, breeding and popularization of new tobacco varieties, infrastructure construction and modern tobacco agriculture development.
