Method for increasing the thickness of tobacco flakes on the lower middle portion of flue-cured Yunnan tobacco and increasing fragrance

Abstract

The invention relates to the technical field of flue-cured Yunnan tobacco production and crude tobacco processing, in particular to a method for increasing the thickness of tobacco flakes on the lower middle portion of flue-cured Yunnan tobacco and increasing fragrance, and the method comprises the following steps of tobacco field selection, flat land type transplanting, proper resettling stage prolonging, brassinolide spraying, early harvesting of tobacco leaves on the lower middle portion and fragrance increasing of the tobacco leaves on the lower middle portion. The fragrance increasing of the tobacco leaves on the lower middle portion comprises the following steps of fresh tobacco picking and sorting, layered dense tobacco loading, low-temperature and medium-humidity color changing in a curing barn, medium-temperature and low-humidity color fixing in the curing barn and medium-temperature and medium-humidity rib drying in the curing barn. According to the method for increasing the thickness of the tobacco flakes on the lower middle portion of the flue-cured Yunnan tobacco and increasing the fragrance, the leaf identity, the oil content and the fragrance on the lower middle portion of a tobacco plant are improved, the consistency of the appearance quality of the flue-cured tobacco is guaranteed, and the quality of the flue-cured tobacco is improved. The method is used for overcoming the defects in the prior art.

Description

technical field [0001] The invention relates to the technical fields of flue-cured tobacco production and raw tobacco processing, in particular to a method for increasing the thickness of the middle and lower slices of the flue-cured tobacco and increasing the aroma. Background technique [0002] The characteristics of tobacco leaves are closely related to the ecological environment of tobacco planting. Hunan Luzhou-flavor tobacco leaves have the characteristics of rich aroma, good smoke permeability, strong burnt sweetness, mellow and full-bodied, and comfortable aftertaste. It is an important part of the development of Chinese cigarettes. An important raw material for cigarette harm reduction and tar reduction, which is of great significance for in-depth development. [0003] Chenzhou City, Hunan Province belongs to the subtropical monsoon climate zone, with mild climate, abundant rainfall, sufficient light and heat, and long frost-free period. The soil is mostly red soil,...

AI Technical Summary

Problems solved by technology

However, affected by specific factors such as the environment, Hunan Chenzhou tobacco leaves still have problems such as thin identity, insufficient oil content, and insufficient aroma in the middle and lower tobacco leaves, resulting in poor industrial availability of the middle and lower tobacco leaves, that is, the middle and lower tobacco leaves are difficult to meet the requirements of tobacco production. Therefore, improving the quality of the middle and lower tobacco leaves has become a key factor restricting the high-quality development of the tobacco area.
