Problems solved by technology

[0011] However, the traditional method mainly focuses on the color changes of tobacco leaves and main veins, and does not realize that the maturity of tobacco leaves is the result of physiological and biochemical changes in the substances in tobacco leaves

Embodiment 1

[0064] Embodiment 1: according to the tobacco leaf that the method for the present invention gathers

[0065] 1. Harvesting of tobacco leaves

[0066] Harvest as follows:

[0067] (1) Lower leaves

[0068] Leaf veins, 2 / 3 of the main veins turn white, from the base of the leaf to more than the tenth branch or more than 65% of the leaf area turns yellow or basically turns yellow, both sides of the branch are slightly green; the hair on the tip of the leaf is slightly receded, and the angle between the stem and the leaf is close to 90° °.

[0069] (2) Middle leaves

[0070] The greenness of the leaves is reduced, the surface of the leaves is light yellow, the tips and margins of the leaves turn yellow and white, the main veins are completely white, 1 / 3 to 2 / 3 of the branch veins turn white, the base of the leaves is yellowish, and 80% of the leaves are from the base to the sixth branch The leaf area turns yellow or basically turns yellow, and the sides of the branch veins a...

Embodiment 2

[0075] Example 2: Tobacco leaves harvested according to traditional methods

[0076] 1. Harvesting of tobacco leaves

[0077] The tobacco leaves of Example 1 are collected from the same field and the same year, and the planting methods of the tobacco leaf varieties and tobacco seedlings are also the same.

[0078] Specifically, harvest according to the following methods:

[0079] Lower leaves: leaf surface yellow-green, 6-7 percent yellow, main veins whitened by more than 1 / 2;

[0080] Middle leaves: the leaf surface is light yellow, 7-8 percent yellow, and more than 2 / 3 of the main veins turn white;

[0081] Upper leaves: Leaf surfaces are light yellow, 8-9 percent yellow, and more than 3 / 4 of the main veins turn white.

[0082] 2. Baking of tobacco leaves

Embodiment 3

[0084] Embodiment 3: the comparison of the macro index of the tobacco leaf harvested by different methods

[0085] 1. Experimental samples

[0086] The tobacco leaves of different harvesting methods of Examples 1 and 2 were processed through the same curing process.

[0087] 2. Experimental method

[0088] The metrics for comparison are shown in Table 1 below.

[0089] Leaf structure, chroma, and oil content are judged according to the national standard of "Cured Tobacco" (GB 2635-92, Flue-cured Tobacco [S]) and physical standard samples.

[0090] 3. Experimental results

[0091] As in Table 1 below.

[0092] Table 1: Comparison of macro indicators of tobacco leaves harvested by different methods (upper leaf, middle leaf and lower leaf are compared as a whole)

[0093]

[0094] The results show that the performance of the roasted tobacco leaves harvested by the method of the present invention is relatively consistent in maturity, and the roasted leaves have no or ver...

Abstract

The invention belongs to the tobacco field, and relates to a method for determining maturation of tobacco leaves and a method for harvesting tobacco leaves. According to the appearance of different growth characteristics of the tobacco leaves in the filed, the determination can be carried out according to color of each part of the tobacco leaf, the whitening degree of main and branch vein, fuzz shedding condition and size of stem and leaf, so that maturation harvest of the tobacco leaf at each part can be reached. Compared with a traditional method, the method increases operability and accuracy of the tobacco leaves, concrete index and different degrees and levels for determining can be highlighted; so that the method has stronger pertinency, regularity and comprehensiveness, and is easy to be grasped, and is suitable for harvesting the tobacco leaves after optimizing a structure of the current tobacco leaves.

Description

technical field [0001] The invention belongs to the field of tobacco, and relates to a method for harvesting tobacco leaves and a method for preparing cigarettes. The invention also relates to a tobacco leaf curing method or a tobacco leaf processing method. Background technique [0002] Field maturity is divided into physiological maturity and technological maturity from the perspective of tobacco physiology and cigarette industry demand. Generally speaking, the maturity of tobacco leaves refers to the degree of change in physiological and biochemical transformation suitable for the raw materials required by the cigarette industry after the growth and development of tobacco leaves and the accumulation of dry matter, including the coordination of chemical components and the suitability of physical states, that is, process maturity. . [0003] Physiological maturity means that the tobacco plant is in the later stage of growth and development, and the dry matter accumulation...
