Abstract

The invention discloses a method for curing tobacco leaves of the flue-cured tobacco variety RG11 matured under the condition of rainy and little sunshine. According to the baking characteristics of the tobacco leaves of the flue-cured tobacco variety RG11 under the condition of rainy and little sunshine, the whole process of tobacco leaf baking is carried out according to the temperature, humidity The tobacco leaf curing process is divided into three stages and seven steps, including the early yellowing stage, the middle yellowing stage, the late yellowing stage, the early color fixing stage, the late color fixing stage, the early gluten-drying stage, and the late gluten-drying stage. The quality of the finished tobacco leaves has been greatly improved; this curing method is highly operable, and can significantly improve the quality of the flue-cured tobacco variety RG11 and the proportion of high-quality tobacco, and reduce the rate of blue smoke; Variety RG11 has a unique style, which improves the planting income of flue-cured tobacco variety RG11.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf curing, in particular to a tobacco leaf curing method of the flue-cured tobacco variety RG11 matured under the conditions of abundant rain and little sunshine. Background technique [0002] Curing is one of the important measures of tobacco leaf production. The fresh tobacco leaves harvested in the field must be roasted to reflect its excellent quality and high commodity value. The curing characteristics of tobacco leaves are restricted by many factors such as variety, soil and climate, among which the most important factor is the variety. Different flue-cured tobacco varieties have different curing characteristics. At present, the flue-cured tobacco curing process is generally a three-stage curing process, that is, the curing process is divided into three stages: yellowing, color fixing, and tendon drying. Temperature 36-38°C, yellowing complete temperature 40-42°C, wet bulb temperature 1-4...
