Problems solved by technology

Especially in the context of the current inventory of tobacco leaves, the number of remaining tobacco leaves is reduced, and the phenomenon of excessive nicotine content in the upper tobacco leaves is more common, which seriously affects the industrial availability of the upper tobacco leaves, resulting in the inability of the upper tobacco leaves to be used in large quantities in cigarette products. The sustainable development of tobacco agriculture has also greatly affected the economic income of tobacco farmers

Embodiment 1

[0021] A treatment agent for reducing the nicotine content in the upper tobacco leaves after topping. The treatment agent is composed of salicin hydroxamic acid and glucose, wherein the mass ratio of salicin hydroxamic acid to glucose is 1:2500.

[0022] The specific steps for reducing the nicotine content of the upper tobacco leaves by the slow release method:

[0023] Weigh the agar powder according to the mass volume fraction of 0.8%-1%, and measure the water, that is, add 0.8-1.0g agar powder per 1000mL of water; after mixing the agar powder and water, heat the agar powder to boiling with a microwave oven to fully dissolve the agar powder and No bubbles, then cool to 50-55°C for later use.

[0024] A certain amount of treatment agent was weighed and poured into the agar solution, and stirred evenly, the concentration of salicin hydroxamic acid was 20 mg / L, and the concentration of glucose was 50 g / L. Pour the solution into the glue filling box, the thickness of the glue f...

Embodiment 2

[0027] The specific steps for reducing the nicotine content of the upper tobacco leaves by the quick-acting method:

[0028] Take by weighing a certain amount of the treatment agent for reducing the nicotine content of upper tobacco leaves provided by Example 1, pour it into water, make the concentration of salicin hydroxamic acid be 20mg / L, and the concentration of glucose be 50g / L, and then add 1mL Tween 20 was used as an adhesive, and stirred evenly for later use.

[0029] After the tobacco plants are topped, the upper tobacco leaves are sprayed once with a sprayer immediately, and the upper tobacco leaves are sprayed once after the lower tobacco leaves are harvested.

[0030] apply effects

[0031] The upper tobacco leaves after topping were treated with the methods of Examples 1 and 2 respectively, and the blank was used as a control.

Abstract

The invention provides a treatment agent and a treatment method of reducing a nicotine content of an upper tobacco leaf of a cured tobacco and belongs to the field of plant growth regulation. The treatment agent and the treatment method solves the problem of influence on the quality of the tobacco leaf due to quick increase of the nicotine content of the upper tobacco leaf after topping. The treatment agent is a mixture of salicylhydroxamic acid and glucose. The invention further provides the treatment method of reducing the nicotine content of the upper tobacco leaf after the topping. The method comprises the steps of dissolving salicylhydroxamic acid and glucose in agar gel to prepare an agar gel block, fixedly placing the agar gel block at a cutting surface of a topping stem of a tobacco plant, or spraying a mixed solution of salicylhydroxamic acid and glucose onto the upper tobacco leaf after the topping of the tobacco plant and harvesting of a lower tobacco leaf. The treatment agent of reducing the nicotine content of the upper tobacco leaf of the cured tobacco is simple in formula, significant in effect, and flexible in use method, can significantly reduce the nicotine content of the upper tobacco leaf after the topping and improves the quality of the tobacco leaf.

Description

technical field [0001] The invention belongs to the field of plant growth regulation, and in particular relates to a treatment agent and a treatment method for reducing the nicotine content of upper tobacco leaves of flue-cured tobacco. Background technique [0002] During the cultivation and management of tobacco, topping is required to promote the vegetative growth of tobacco leaves. However, after topping, a series of changes have taken place in the metabolism of the tobacco plant, especially in the upper tobacco leaves, and the content of nicotine increases rapidly. Especially in the context of the current inventory of tobacco leaves, the number of remaining tobacco leaves is reduced, and the phenomenon of excessive nicotine content in the upper tobacco leaves is more common, which seriously affects the industrial availability of the upper tobacco leaves, resulting in the inability of the upper tobacco leaves to be used in large quantities in cigarette products. The sus...
