Embodiment 1
[0036] In the method for determining the origin of flue-cured tobacco in this embodiment, the tobacco leaf positions of the tobacco leaves to be determined are not distinguished, including the following steps:
[0037] 1) Establish a discriminant model for the quantitative indicators of tobacco leaf color and the place of flue-cured tobacco production. The discriminant models for different regions are as follows:
[0043] In formula (1) ~ formula (5), X 1 Positive red and green index a * ; X 3 Is the difference between the front...
Embodiment 2
[0051] In the method for determining the origin of flue-cured tobacco in this embodiment, the tobacco leaf to be determined as the upper leaf includes the following steps:
[0052] 1) Establish a discriminant model for the quantitative indicators of tobacco leaf color and the place of flue-cured tobacco. The discriminant models for different regions are as follows:
[0058] In formula (6) ~ formula (10), X 1 Positive red-green index a * ; X 2 Is the positive yellow-blue index b * ; X 3 Is the difference between the front and back brightness ΔL * ; X 4 Is the...

Abstract
The invention relates to a discrimination method of flue-cured tobacco producing areas. The discrimination method comprises the following steps: establishing a discrimination model involving a positive red-green index, a positive yellow-blue index, positive and negative brightness difference, positive and negative whiteness index difference, positive and negative total color difference, a positivewhiteness index and positive color saturation of tobacco leaves and the flue-cured tobacco producing areas; detecting quantitative color indexes of tobacco leaves to be discriminated, and substituting into the discrimination model. By the discrimination method of the flue-cured tobacco producing areas, provided by the invention, the screened quantitative color indexes such as the positive red-green index, the positive yellow-blue index and the like have very strong correlativity with the flue-cured tobacco producing areas; by a modeling method, regional appearance characteristics of the tobacco leaves from different producing areas can be reflected very well, so that the flue-cured tobacco producing areas can be effectively identified by using the established discrimination model; the quantitative color indexes can be conveniently detected by using a colorimeter, the detection process is simple, and requirements on the detection environment and samples are low; the discrimination method has a very good application prospect in the process of precisely evaluating the quality of the tobacco leaves and automatically classifying and sorting the tobacco leaves.
Description
Technical field [0001] The invention belongs to the field of tobacco leaf evaluation, and specifically relates to a method for identifying the producing area of flue-cured tobacco. Background technique [0002] Tobacco is an important economic crop in my country, and the quality of tobacco leaves is closely related to genetic factors, cultivation measures, preparation techniques and the environment of the production area. Among them, the environment of the production area (altitude, temperature and humidity, climatic conditions, etc.) has an extremely obvious impact on the quality of tobacco leaves. The quality and style of tobacco leaves in different production areas in my country are significantly different. There are both classic divisions of strong flavor, fresh flavor, and intermediate flavor. There are further subdivided eight fragrance ecological regions. Different styles of tobacco leaves provide a rich raw material foundation for various types of Chinese cigarettes dev...
