Problems solved by technology

In recent years, with the rapid development and application of information technology and the promotion of homogenization of advanced cultivation techniques, the quality and style of domestic flue-cured tobacco leaves have shown a tendency to converge. Increased the difficulty of leaf group formulation for formulators, which ultimately affected the quality and characteristics of cigarette products
Therefore, how to change the quality and style of flue-cured tobacco is a technical problem generally studied by those skilled in the art. Method" (application number 201110073505.7) has proposed two solutions, but both have problems such as complex methods, high requirements, and difficult implementation

Embodiment 1

[0019] Flue-cured tobacco Yunyan 87 was selected as the implementation object.

[0020] The first step: planting. The planting was carried out in Fangxian County, Shiyan City, Hubei China Tobacco's tobacco raw material base. The specific planting site was selected at Xiping Experimental Station in Fangxian County.

[0021] The second step: harvest. Flue-cured tobacco reaches maturity standards (the main veins of the lower leaves are all white and shiny, 1 / 3 of the branch veins are white, the leaf surface is yellow-green, the leaf tips are drooping, the leaf margins are slightly withered, and the hairs are less lost; the main veins of the middle leaves are all white and shiny, and the branch veins are 1 / 3 ~2 / 3 turns white, with yellow and yellow-white patches on the leaf surface, yellow-green obvious, the leaf ears are slightly yellow to light yellow, and some hairs are off; the main veins of the upper leaf are all white and shiny, and the branch veins 2 / 3 become white, and the lea...

Embodiment 2

[0029] The flue-cured tobacco Yunyan 87 was selected as the implementation object, and the method steps were the same as those in Example 1, except that the urea sprayed on the kilogram leaf surface was 0.05 g.

Embodiment 3

[0031] The flue-cured tobacco Yunyan 87 was selected as the implementation object, and the method steps were the same as in Example 1, except that the urea sprayed on the leaf surface of kilograms was 0.2g.

Abstract

The invention discloses a preparation method for cured tobacco leaves. The method comprises the steps of cured tobacco plantation, tobacco leaf harvest and curing. In the step of tobacco leaf harvest, the tobacco leaves are harvested from bottom to top one by one according to tobacco leaf growth positions, 4-5 tobacco leaves are harvested each time, urea solution is evenly sprayed onto surfaces of the tobacco leaves after harvesting, urea sprayed onto the leaf surfaces per kg is 0.05-0.2g; and the tobacco leaf curing comprises the steps of tobacco leaf withering, yellowing, browning and killing-out. Characteristic aroma of the prepared cured tobacco leaves is remarkably weakened, aroma quality style is similar to air-cured tobacco leaves, strength is slightly high, satisfaction is strong, concentration is high, the cured tobacco leaves are full and mellow, irritation is small, smoke is smooth, the application range is greatly expanded, and technical support is provided for enriching tobacco leaf quality styles and meeting diversified raw materials requirements of low-tar low-harm cigarette products.

Description

Technical field [0001] The invention belongs to the technical field of tobacco production, and specifically relates to a method for preparing flue-cured tobacco leaves. Background technique [0002] In the process of long-term cultivation of tobacco, due to the differences in natural environment, cultivation conditions, preparation methods and use requirements, various types have been formed. According to tobacco leaf quality characteristics, biological characteristics and cultivation methods, cultivated tobacco in my country can be divided into 6 types: flue-cured tobacco, sun-cured tobacco, air-cured tobacco, burley tobacco, oriental tobacco and yellow flower tobacco. Different types of tobacco leaves are different in appearance, chemical composition, smoke characteristics, and uses. The tobacco industry makes appropriate blends according to their quality characteristics to produce tobacco products that meet the requirements and flavors of different people. [0003] Flue-cured t...
