Embodiment 1

[0035] A method of increasing the usability of upper tobacco leaves, said method comprising the steps of:

[0036] The first step is to determine the maturity standard of the upper tobacco leaves of flue-cured tobacco, that is, the top 1 and / or 2 leaves are mainly yellow, the main veins are all white and shiny, and most of the lateral veins are white, specifically the proportion of the lateral veins. At least 2 / 3, the angle of the stem and leaf is close to a right angle, that is, the angle between the stem and the leaf is not less than 82°, the leaf is curved and arched, the arch angle is 135°-165°, the leaf surface is shrunken, and the yellow mature spots on the leaf surface are obvious ;

[0037] Among them, the judging method based on yellow is: take photos of tobacco leaves through high-resolution equipment, which refers to mobile phones or cameras with a pixel size of not less than 20 million pixels, and import the photos into Adobe Photoshop CC 2018 for image processing ...

Embodiment 2

[0052] A method of increasing the usability of upper tobacco leaves, said method comprising the steps of:

[0053] The first step is to determine the maturity standard of the upper tobacco leaves of flue-cured tobacco, that is, the top 1 and / or 2 leaves are mainly yellow, the main veins are all white and shiny, and most of the lateral veins are white, specifically the proportion of the lateral veins. At least 2 / 3, the angle of the stem and leaf is close to a right angle, that is, the angle between the stem and the leaf is not less than 82°, the leaf is curved and arched, the arch angle is 135°-165°, the leaf surface is shrunken, and the yellow mature spots on the leaf surface are obvious ;

[0054] Wherein the method for judging that the parietal leaf is mainly yellow is as follows: take photos of tobacco leaves by high-resolution equipment, import the photos into Photoshop image processing software, sample them with a straw tool, and determine the color value with RGB color m...

Embodiment 3

[0067] A method of increasing the usability of upper tobacco leaves, said method comprising the steps of:

[0068] The first step is to determine the maturity standard of the upper tobacco leaves of flue-cured tobacco, that is, the top 1 and / or 2 leaves are mainly yellow, the main veins are all white and shiny, and most of the lateral veins are white, specifically the proportion of the lateral veins. At least 2 / 3, the angle of the stem and leaf is close to a right angle, that is, the angle between the stem and the leaf is not less than 82°, the leaf is curved and arched, the arch angle is 135°-165°, the leaf surface is shrunken, and the yellow mature spots on the leaf surface are obvious ;

[0069] Wherein the method for judging that the parietal leaf is mainly yellow is as follows: take photos of tobacco leaves by high-resolution equipment, import the photos into Photoshop image processing software, sample them with a straw tool, and determine the color value with RGB color m...

Abstract

The invention discloses a method for improving the availability of upper tobacco leaves, which comprises the following three steps: first, judging the maturity standard of upper tobacco leaves of flue-cured tobacco; 2, postponing the harvest period when the mature standard is reached; 3, performing stratified baking after harvesting: controlling wet bulb temperature and temperature difference between dry bulb and wet bulb in yellowing period, prolonging yellowing period time, dehumidifying at high speed before fixing color, and controlling total baking time. The first step discloses a new accurate judgment method of the upper tobacco leaf maturity standard. The second step includes: S1, control time limit; S2, harvest time point; S3, harvest selection; S4, collecting and shipping. The third step includes: S1, controlling the wet bulb temperature and the temperature difference between the dry bulb and the wet bulb; S2, prolonging the yellowing period time; S3, dehumidifying at high speed before fixing color; 4: grasping the baking time. The method is remarkably effective in improving the external quality and the internal quality of the upper tobacco leaf from the processes of the maturity of the upper tobacco leaves, the picking method and the curing process, and effectively improving the usability of the upper tobacco leaf.

Description

technical field [0001] The invention relates to the technical field of tobacco value enhancement, in particular to a method for improving the availability of upper tobacco leaves. Background technique [0002] Nowadays, most of the purchases of tobacco leaves are for the purchase of middle-grade tobacco leaves of flue-cured tobacco. However, in the actual tobacco leaf production process, the output of upper tobacco leaves accounts for 35%-40% of the total output. The supply of middle-grade tobacco leaves is affected by the production structure. Due to limitations, it is difficult to meet market demand. Relying solely on the top tobacco leaves in the middle to produce cigarettes limits the overall utilization of base tobacco leaves. Therefore, the development and utilization of top tobacco is a trend and a challenge to increase cigarette production. For a long time, cigarette products on the market have been in short supply. status. [0003] In the traditional production pr...
