After mainenervations being drawn out and being dried for 4 hours at 60℃,1156 samples of tobacco leaves from different tobacco producing-area were made into powder (≤0.13 mm). Reducing sugar, total sugar, nicotine, nitrogen, potassium and chlorine of more than 1000 samples from different tobacco producing-area were determined with classical chemical or instrumental methods. By scanning these samples with Fourier transform Near Infrared spectrometer (MARIXT-I produced by Bucker) we obtained their spectrograms, pretreated the spectrograms with a chemometrics software (OPUS 5.5) to debase the noises influence on spectrum information, and built a chemometrics model by means of Partial Least2Squares. The chemometric model was optimized some times and validated with some other samples.
