摘要
Abstract
In this paper, AOTF - NIR (AOTF - Near Infrared Reflectance Spectroscopy) technique was used to establish a rapid and nondestructive detection method for the determination of 5 chemical components of growing tobacco leaf in the field. Partial least square regressive method was used to build the calibration mathematical models between the NIR spectra information and the content of each chemical component based on the calibration set which consisted of 182 samples, and 30 samples in the validation set were predicted. The predictive results showed that the average relative errors of the prediction for nicotine, total nitrogen, total sugar, reducing sugar and potassium were 3.73% , 3. 89% , 3. 78% , 2. 88% and 4. 37% respectively. The original chemical values and predictive values of validation set samples were tested by the twin t -test, and no significant difference was found between them, indicating that the established mathematical models were available. The presented method was accurate, reliable, convenient and nondestructive, and it could be used for the rapid and quantitative detection of nicotine, reducing sugar, total sugar, total nitrogen and potassium of growing tobacco leaf in the field.关键词
