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 invention provides a method for evaluating the chemical quality of tobacco leaves, which can effectively fuse index weights of chemical components determined by different methods, further improvesthe balance of the index weights, and considers the correlation, difference and gray property of the chemical components. The situation that the grade limit value is not easy to determine possibly occurring in tobacco chemical quality set pair analysis is considered; the relation degree is determined according to the grade to which the measured value of the chemical component belongs, and the homogeneity, the difference degree and the contrary degree are quantified by the weight value, so that the possibility of inconsistent result judgment caused by selection of different grade limit valuesis reduced, and the chemical quality evaluation method better conforms to 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...
