Abstract:

Currently, tobacco leaves of the formula processing was processed according to the grades and parts of the whole tobacco leaf, which ignored the information of chemical substance of the regional distribution in the single tobacco leaf. 48 sampling points within general chemical composition (nicotine, total sugar, K+, Cl-) measured were extracted from single flue-cured tobacco leaf by self-made hole with thin wood. Using geostatistical software (GS+) for windows, SPSS, Management zone analyst software analyze. The results showed that the ratio of nugget variance to sill variance of nicotine, total sugar, potassium ion, chloride ion > 75% indicated weak spatial dependence, but large spatial variability from Kriged map of general chemical composition; Only principal component 1, in 4 substances eigenvalue with 2.864 was greater than 1, accounting for 71.64% variable; The single flue-cured leaf can be accurately divided into four regions. It should be able to provide useful information for threshing and redrying, blending leaf groups of cigarette factory.
