Problems solved by technology

[0006] The purpose of the present invention is to provide a method for evaluating the chemical quality of tobacco leaves, so as to solve the arbitrariness of calculating the weight of chemical components by using the subjective weighting method in the above-mentioned technology, the calculation steps of the combination weight are not clear, and the chemical quality set of tobacco leaves is limited to the analysis model. Defects such as evaluation ratings

Abstract

The present invention provides an evaluation method for the chemical quality of tobacco leaves. The present invention can effectively integrate the weights of chemical composition indexes determined by different methods, further improve the balance of index weights, and take into account the correlation and difference of chemical composition and grayness; the present invention considers that the analysis of the chemical quality set of tobacco leaves may have a situation that the grade boundary value is not easy to determine, and determines the degree of connection according to the grade of the measured value of the chemical composition, and quantifies the degree of identity, difference and opposition with weight values, reducing It eliminates the possibility of different judgments caused by the selection of different grade threshold values, and is more in line with the reality of chemical quality evaluation.

Description

technical field [0001] The invention belongs to the field of tobacco leaf quality evaluation, in particular to a method for evaluating the chemical quality of tobacco leaves. Background technique [0002] The chemical quality of tobacco leaves is an important part of the quality of tobacco leaves. The comprehensive evaluation of tobacco leaf chemical quality can provide reference and basis for tobacco planting division, selection of tobacco leaf varieties, adjustment of production measures, etc.; comprehensive evaluation of tobacco leaf chemical quality refers to the evaluation of chemical composition indicators and their corresponding The closeness of the standard or suitable range, because the chemical composition index contributes differently to the tobacco leaf quality, therefore, it is necessary to assign different weights to the chemical composition index. [0003] In order to overcome the shortcomings of a single weighting method, the academic community has proposed a...
