Method for increasing yield and improving quality of upper tobacco leaf

Abstract

Here is a method for production increasing and quality improving of tobaccoí»s upper leaves, whose characteristics are: Using wood or bamboo to make carrier swab; taking ethyl as solvent to confect fruitone solution; after the fruitone dissolves completely, add emulsification film former to execute drug solution; air the swab after dipping in the drug solution to crank out carrier swab; after tobacco plant is top-removed, intervene the carrier swab between the third and the forth leaves slantingly, and one swab is ok for one plant. Through using plant growing modifier effectively in this invention, tobaccoí»s upper leaves can be accelerated to increase and output can be boosted; also its nicotine content can be decreased and the kalium content can be increased, accordingly the quality of tobacco and its industrial usability is modified.

Description

Technical field: [0001] The invention relates to a method for regulating plant growth, more specifically a method for regulating the yield and quality of tobacco upper leaves. Background technique: [0002] Tobacco is harvested from leaves, and nicotine in tobacco leaves is a physiologically functional substance required by smokers, but the nicotine content must be within an appropriate range, too high or too low will affect the quality of tobacco leaves. The upper leaves of tobacco in my country mainly have the following problems: [0003] 1. The nicotine content is too high, which is difficult for the cigarette industry to utilize; [0004] 2. The potassium content of tobacco leaves is low, which affects the combustion performance of tobacco leaves; [0005] 3. The leaves are small and thick, which leads to a reduction in yield and affects the economic benefits of tobacco farmers and tobacco companies. [0006] At present, the following methods are often used in tobacco...

AI Technical Summary

Problems solved by technology

[0003] 1. The nicotine content is too high, which is difficult for the cigarette industry to utilize;

[0004] 2. The potassium content of tobacco leaves is low, which affects the combustion performance of tobacco leaves;

[0005] 3. The leaves are small and thick, resulting in reduced yield and affecting the economic benefits of tobacco farmers and tobacco companies

If it rains within 24 hours after application, the effect will be significantly reduced

[0014] 3. The effect of foliar spraying is relatively concentrated, with fast action and high intensity, but the timeliness is short, generally only lasts for 15-25 days, and it takes 50-60 days to grow from spraying to upper leaf harvesting, often It will lead to the increase of nicotine in the later stage. If the number of spraying is increased, it will lead to problems caused by increased usage
