Problems solved by technology

[0005] At present, the method of topping is often used in agricultural production to increase the nicotine content of tobacco, but this method is limited by many factors such as varieties and cultivation conditions.
Since there are many factors affecting the nicotine content in tobacco leaves, controlling a single factor cannot guarantee stable tobacco leaf quality

Abstract

The invention discloses a method for increasing tobacco nicotine yield per unit land area. According to the method, comprehensive management control is carried out on each stage of tobacco cultivation and a conditioning and drying stage, a series of measures for increasing the nicotine content of tobacco leaves such as low ridging, high-density cultivation, budding topping without axillary bud removal, harvesting from top to bottom, rolling fixation and the like are adopted for optimization control, and the synthesis and degradation rules of nicotine in the tobacco leaves in the growth process and the modulation process are fully combined, so that stable production of the high-nicotine-yield tobacco leaves is achieved, traditional tobacco leaf production transformation and diversified development are achieved, the international competitiveness of tobacco under the new situation is improved, and an industrial chain of tobacco agricultural production under the new situation is formed. The high-nicotine tobacco leaf production requirement is combined, highly mechanized production is adopted, the labor input in the tobacco production process is reduced, the labor cost is reduced, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation, and in particular relates to a method for increasing the yield of tobacco nicotine per unit land area. Background technique [0002] In recent years, with the rapid growth of heat-not-burn tobacco products and electronic cigarettes, the market size of new tobacco products will further expand, and global new tobacco products will grow rapidly. [0003] At present, electronic cigarettes, the main products of new tobacco products, mainly include heated cigarettes and steam-type cigarettes. The nicotine of heated cigarettes mainly comes from tobacco sheets, and the sheets are originally made of waste tobacco leaves, so the sheets themselves contain nicotine, but due to the The taste of cigarettes is not as good as that of traditional cigarettes, so a small number of heated cigarettes will also have additional nicotine added. Vaping electronic cigarettes need to completely add nicotine (n...
