Abstract:

In order to reveal the spatial variation of sugar, nicotine in Yongzhou Tobacco, and to provide guidance for area planning, procurement of raw materials by tobacco industrial enterprises. In this paper, C3F grade flue-cured tobacco samples were collected in Yongzhou Hunan from 2007 to 2009, The spatial variability of total sugar, reducing sugar, nicotine content and total sugar nicotine ratio were been analyzed by geostatistics. The results showed that the sugar content of tobacco was 27.4%-29.2%, reducing sugar content was 25.8%-27.5%, the nicotine content was 2.4%-2.6% and sugar to nicotine ratio was 12.1-13.6 in most of tobacco Yongzhou. The spatial distribution of total sugar, reducing sugar contents in tobacco and sugar to nicotine ratio showed as the same decreasing trended from east to west, nicotine content was in the opposite, as a decreasing trend from west to east. Nicotine was within the suitable range of high quality tobacco in Hunan Province, the total sugar, reducing sugar, total sugar to nicotine ratio of tobacco in most Yongzhou were highly out of the range except the west Dao Coutny and northern Jiangyong County.
