[0024] Step (1) Tobacco Leaf Selection and Compilation

[0025] (1-1) Determination of the tobacco leaves to be tested

[0026] The nutritional conditions, location and maturity of the tobacco leaves to be tested should be balanced and consistent.

[0027] (1-2) Labeled tobacco leaves

[0028] In order to ensure the accuracy of the test, representative tobacco leaves were determined before the tobacco leaves were installed in the barn, and 18 rods (clips) were processed for each, and their fresh weights were weighed and listed on the record. At the positions of 2, 4, and 6 meters in the room, there are 1 rod (clip) in the middle of the bottom, middle, and upper layers; after the tobacco leaves have regained moisture after curing, they are graded and analyzed for economic properties.

Abstract

The invention discloses a stable-temperatureslow curing method for tobacco Xiangyan 5. Picked Xiangyan 5 tobacco leaves are woven and placed in a flue-curing barn for curing, wherein the curing adopts a three-stage type stable-temperatureslow curing step including a yellowing stage, a color fixation stage and a stem drying stage. With the adoption of the stable-temperature slowcuring process and cooperative control of other parameters such as tobacco weaving and the like, cured tobacco leaves are low in green rate, produce little black smokeand have low mixed-color tobacco proportion and high yellow tobacco proportion; besides, mature degree and looseness degree of the cured tobacco leaves are high; the leaf body is good; oil content is high; the ratio of mid-high grade of tobacco is high; tobacco leaves are high in average priceand good in benefit.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf curing, in particular to a curing process for Xiangyan No. 5 tobacco leaves. Background technique [0002] The new flue-cured tobacco line HN0508 was approved by the National Tobacco Variety Committee and named Xiangyan No. 5. Xiangyan No. 5 has excellent comprehensive traits: For example, 1. Excellent agronomic traits: low temperature resistance, no early flowering, good upper leaf opening, and the number of effective leaves can be stabilized at about 20. It is resistant to black shank and common mosaic The disease resistance is better than that of K326; 2. It is easy to bake: the field is layered and yellowed, it is resistant to maturity, the upper leaves are not easy to hang ash, and the appearance quality of raw tobacco is better than that of K326; The price and high-quality smoke rate are obviously better than K326, which is equivalent to or slightly better than Yunyan 87. 4. High indu...
