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...
