Problems solved by technology

The display of specimens of cured tobacco leaves in the prior art is in the form of compressed sheets, which cannot truly reflect the shape and texture of the cured tobacco leaves, and is not conducive to the display and research of the characteristics of the cured tobacco leaves. Concentrating on research, developed a batch production method of cured tobacco leaf specimens that can reflect the morphological characteristics of cured tobacco leaves as a whole, and achieved good test results

Abstract

The invention discloses tobacco leaf specimen treatment liquid and a flue-cured tobacco leaf specimen batch production and preservation method. The tobacco leaf specimen treatment liquid contains resin, isocyanate, acetone and polyethyleneglycol, the volume ratio of the resin to the isocyanate to the acetone to the polyethyleneglycol is 1: (0.5-1): (1-2): (0.005-0.01), and the resin, the isocyanate, the acetone and the polyethyleneglycol are sequentially added and are evenly mixed. The flue-cured tobacco leaf specimen batch production and preservation method comprises the steps of fixation, treatment by using the treatment liquid, leaf tidying and drying, preservation in inert gas and the like. By using specially prepared tobacco leaf specimen treatment agent, the produced flue-cured tobacco leaf specimens are ensured to be not apt to be mildewed, crushed and decolorized and can be prevented from being eaten by worms. According to tests, the produced flue-cured tobacco leaf specimens are compression-resistant and rubbing-resistant, leaves are not cracked after the leaves are repetitively pressed and the tobacco leaves can be restored to the original shape after pressure is relieved; and the suitable environmental temperature range for preservation is wide and the appearance and the shape of the specimens are not changed after the specimens are alternately preserved under environments at 60 DEG C and 20 DEG C.

Description

technical field [0001] The invention belongs to the technical field of tobacco research and specimen preparation, and in particular relates to a treatment liquid for tobacco leaf specimens with a simple method and a stable and reliable process, and a batch production and preservation method for cured tobacco leaf specimens. Background technique [0002] Plant leaf specimens can well preserve the natural shape of plant leaves, which can be used for teaching, display and research. Tobacco specimens are generally made of freshly picked fresh leaf specimens that have not been roasted, while roasted tobacco leaf specimens are very easy to produce. few. The display of the specimens of the cured tobacco leaves in the prior art is in the form of compressed sheets, which cannot truly reflect the shape and texture of the cured tobacco leaves, and is not conducive to the display and research of the characteristics of the cured tobacco leaves. With painstaking research, a batch product...
