Embodiment 1

[0026] When picking 4-6 tobacco leaves at the top of the tobacco plant, (1) take 50 tobacco plants as a control, and harvest the tobacco leaves normally; (2) take 50 tobacco plants for experimental treatment, dig up the tobacco plants by their roots, and retain the soil on the roots , try to keep the root system intact; transfer the tobacco plants to a greenhouse that can shade the sun, place the tobacco plants leaning against the supports neatly; shield the greenhouse where the tobacco plants are placed from the sun; spray the roots of the tobacco plants every day according to the actual situation Apply appropriate amount of water to keep the roots moist, treat for 2 days, and then harvest the tobacco leaves. The control tobacco leaves and test tobacco leaves were cured according to the tobacco leaf curing process, and the cured tobacco leaves were subjected to sensory quality evaluation and routine chemical composition analysis. The sensory quality evaluation results showed ...

Abstract

The invention provides a method for lowering nicotine and starch content on upper tobacco leaves. When upper portion tobacco leaves are prepared to be picked, tobacco plants with roots are transferred into a greenhouse or house in which sunlight is shielded and are placed centralizedly for treatment for 2-8 days. The method for lowering nicotine and starch content on the upper tobacco leaves effectively promotes conversion of substance of starch, nicotine and the like in the tobacco leaves, the contents of the substances of the starch, the nicotine and the like are lowered, the chemical component coordination of the tobacco leaves is improved, and the maturity and quality of the tobacco leaves are improved.

Description

technical field [0001] The invention relates to tobacco leaf harvesting and tobacco leaf preparation methods, in particular to a method for reducing the nicotine and starch content of upper tobacco leaves, and belongs to the field of tobacco processing. Background technique [0002] Tobacco leaf raw materials are the foundation of the cigarette industry. The chemical composition and coordination of tobacco leaves determine the quality of tobacco leaves, and also determine the smoke characteristics of tobacco leaves and their products to a large extent. Tobacco leaves can be divided into lower leaves, middle leaves and upper leaves according to the growing parts. The lower leaves are generally thinner, light in color, loose in tissue, low in oil, low in total nitrogen and nicotine content, good in combustion, poor in hygroscopicity, low in aroma substances and latent aroma substances, flat in taste, irritating and Small miscellaneous flavors, high stalk content. The middle ...
