Embodiment Construction

[0027] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0028] (1) Data selection: the present invention takes the Zimbabwean tobacco area as the specific embodiment of the foreign target tobacco area, and the flue-cured tobacco field climate data of the Zimbabwean tobacco area and the domestic arbitrary five selected tobacco area ecological climate index data are as table 1:

[0030]

[0031]

[0032] 2) Climate similarity analysis

[0033] Table 2 Climatic similarity between domestic selected smoking areas and Zimbabwean smoking areas

[0034]

[0035] The climate of the Zimbabwe tobacco area and the 5 tobacco areas selected in China are described in the form of vectors by 9 core meteorological f...

Abstract

The invention discloses a method for selecting and verifying the planting regions of foreign flue-cured tobacco varieties. The cosine value of an included angle between the same climate indexes of domestic selected tobacco regions and a foreign target tobacco region based on years of climate monitoring data of high-quality tobacco regions at home and abroad in order to evaluate the climate similarity among different tobacco planting regions, and the similarity is high if the value is close to 1; and the Euclidean distance value among the tobacco leaf quality indexes is calculated based on thedetection data of the appearance quality, the conventional chemical composition and the sensory quality of flue-cured tobacco leaves in the tobacco regions to evaluate the tobacco leaf quality similarity among different tobacco regions and verify the tobacco leaf quality similarity between the selected domestic tobacco regions and the foreign target tobacco region, the similarity is low if the distance value is large, and two algorithms are combined to finally determine a domestic tobacco planting region most close to the foreign target tobacco region in climate and quality styles. In the method of the embodiment of the invention, the Zimbabwe tobacco region is used as the foreign target tobacco region.

Description

technical field [0001] The invention relates to a method for selecting and verifying planting areas of imported flue-cured tobacco varieties, and belongs to the technical field of cigarette raw material industry. Background technique [0002] In the field production of flue-cured tobacco, experts at home and abroad agree that the style and characteristics of tobacco leaves are mainly determined by the ecological environment of the planting place, the variety of tobacco leaves and the production technology. Among them, the ecology determines the characteristics, the varieties highlight the characteristics, and the technical guarantee characteristics. At present, with the development of cigarette brands, the cigarette industry's demand for high-aroma, high-concentration and low-harm tobacco leaf raw materials has become increasingly prominent, which has become a key factor restricting the layout of raw material bases of major domestic cigarette companies. Imported tobacco lea...
