Method for preparing water-cured ripe tobacco leaves in shading environment

Abstract

The invention discloses a method for preparing water-cured ripe tobacco leaves in a shading environment, which is characterized in that shading and water culture are synergistically carried out; shading refers to that tobacco plants growing in the field are cut off at the roots or stems and then concentrated in the shading environment, so photosynthesis of tobacco leaves is prevented; in the stepof water culture, the cut ends of the cut tobacco plants are immersed in water, sufficient water is provided for the tobacco plants, and physiological metabolism of tobacco leaves in the ripping process is maintained; and when the maturity of the tobacco leaves reaches the process maturity requirements, subsequent blending and drying processing are carried out. According to the invention, life vitality of tobacco leaves growing on tobacco plants can be maintained while photosynthesis is inhibited, so physical and biochemical changes of the tobacco leaves are converted to the direction beneficial to quality improvement, the maturity of the tobacco leaves is improved, particularly, the leaf structure of the upper tobacco leaves is looser and softer, the industrial availability is improved, and the purposes of disaster prevention, disaster reduction, quality guarantee and stable harvesting are achieved.

Description

technical field [0001] The invention belongs to the technical field of tobacco harvesting and modulation, in particular to the tobacco leaf maturity technology. Background technique [0002] The types of artificially planted tobacco are divided into flue-cured tobacco and air-cured tobacco (mainly Burley tobacco, oriental tobacco) according to the modulation method. The modulation process is a process of physical and biochemical changes inside the tobacco leaves accompanied by dehydration and drying. The tobacco leaf modulation process starts from field harvesting (or harvesting) fresh tobacco (Raw) to the end of leaf drying, and the key technology is tobacco leaf maturity (Maturity). [0003] The well-known definition of tobacco leaf maturity refers to the degree of maturity of the cured tobacco leaf, which is the degree or state that the internal physical and biochemical changes in the appearance of the tobacco leaf meet the requirements of cigarette processing and meet th...

AI Technical Summary

Problems solved by technology

[0013] 3. Due to the crop rotation arrangement, when the planting season of the tobacco crop comes, the tobacco leaves that are not mature enough in the field have to be harvested in advance

[0014] 4. Since the capacity of the barn is basically fixed, when the number of mature tobacco leaves harvested in the field cannot meet the capacity requirements of the barn, other tobacco leaves that are not mature enough in the field have to be harvested in advance

[0015] 5. When the nutrients accumulated by the tobacco leaves are uncoordinated or excessive or insufficient, it is difficult to make the tobacco leaves reach the ideal maturity state in the field growth stage

[0016] 6. When the tobacco harvesters are not sure about the maturity of the tobacco leaves, they mistakenly harvest the tobacco leaves that are not mature enough

[0018] 1. Tobacco leaves that do not reach the process maturity state in the field growth stage are difficult to achieve the ideal maturity state when entering the modulation stage

[0019] 2. Even if the tobacco leaves reach the mature state in the field growth stage, if the modulation is not done properly in the modulation stage, there will be a problem of insufficient ripening after modulation

Harvesting fresh tobacco leaves is to pick the tobacco leaves growing on the stems of the tobacco plants in the field. There are problems such as damage, suffocation and suffocation during the operation process, and premature dehydration of some leaf tissues, which will make the activity of the tobacco leaves worse and affect the quality of the tobacco leaves. The biochemical changes are normal; the maturity of each part of the tobacco leaves harvested with stems is inconsistent, and the uniformity (Uniformity) of the tobacco leaves after conditioning is poor, and there are more mixed colors (Mixed color) and damage (Injury); the upper leaves have stems Although harvesting can improve the quality of tobacco leaves after conditioning to a certain extent, it requires more fuel and more curing time for the conditioning process of flue-cured tobacco

[0022] As mentioned above, agricultural production is limited by many objective factors, making it difficult to achieve the desired maturity of tobacco leaves

In actual production, the problem of insufficient maturity of tobacco leaves is common, especially the upper tobacco leaves have poor maturity and rigid structure, which affects the industrial usability of tobacco leaves
