Analysis on Time Variance Characteristic for Chemical Composition and Coordination of Flue-cured Tobacco Leaf in Pengshui County of Chongqing City
摘要
Abstract
[ Objective] The study aimed to obtain the time variation characteristics for the quality of tobacco leaf in Pengshui County. [ Method] The chemical compositions and their coordination indicators for 3 groups of upper leaf(B2F) , middle leaf (C3F) and lower leaf (X2F) in the flue-cured tobacco in the successive 4 years from 2007 to 2010 in Pengshui County, Chongqing City were analyzed. [ Result] In the tobacco leaf production for the successive 4 years, the coefficients of variation of the chlorine content in the upper, middle and lower leaves of the tobacco in Pengshui County were all more than 30% , and the contents of other chemical compositions kept stable basically. In the various indexes that characterized the chemical compositions coordination, the variation coefficients of the potassium -chlorine ratio in the upper, middle and lower leaves were all more than 30% , and that of two sugar ratio and sugar-alkali ratio kept stable basically. [ Conclusion] In addition to the indicators of chlorine content and the potassium-chloride ratio in the tobacco in Pengshui County, other indicators were stable basically. So, it should adjust the chlorine content in the tobacco leaf through the fertilizer-water management to make the chemical compositions in the tobacco leaf more stable and harmonious.关键词
