Problems solved by technology

[0006] However, in practice, in order to improve the control effect, farmers often increase the dosage or mix another medicament at will. This kind of unscientific medication not only fails to achieve the effect of increasing potassium and reducing chlorine in tobacco, but also leads to the waste of plant growth regulators. Residue exceeding the standard

preparation example Construction

[0044] According to one aspect of the present invention, a kind of preparation method of flue-cured tobacco extracting potassium chlorine reducing agent, described method comprises the following steps:

[0045] First, indole acetic acid, gibberellin and epibrassinolide were prepared as solutions respectively, then the solutions of indole acetic acid, gibberellin and epibrassinolide were added to lanolin in sequence, and heated at 35-45°C Stir and mix evenly for 10 to 16 hours under certain conditions to obtain the flue-cured tobacco extracting potassium and chlorine reducing agent.

[0046] The preparation method of the flue-cured tobacco extracting potassium dechlorination agent provided by the present invention comprises the following steps: first, indole acetic acid, gibberellin and epibrassinolide are respectively configured as solutions, and then indole acetic acid, gibberellin and The lactone solution is sequentially added into the lanolin, and stirred and mixed for 10-1...

Embodiment 1～8

[0059] A potassium-increasing and dechlorinating agent for flue-cured tobacco, which is mainly prepared by mixing indole acetic acid, gibberellin and epibrassinolide in lanolin. The indole acetic acid is indole acetic acid.

[0060] The specific qualities of indole acetic acid, gibberellin, epibrassinolide and lanolin in Examples 1-8 are shown in Table 1.

[0061] Table 1: The concrete weight of each raw material in embodiment 1~8

[0062]

[0063] The preparation method of above-mentioned flue-cured tobacco extracting potassium chlorine reducing agent comprises the following steps:

[0064] (1) Prepare the solution: take the raw materials according to the weight in the above table, and then configure the solutions of indole acetic acid, gibberellin and epibrassinolide respectively. The specific configuration method of the solution is:

[0065] Dissolve indole acetic acid in 25mL of ethanol, add 25mL of water, shake well and avoid light for later use;

[0066] Dissolve g...

experiment example 1

[0075] In order to show that the flue-cured tobacco potassium dechlorination agent of the present invention can make the absorption and distribution of tobacco potassium ions and chloride ions more balanced, reduce the content of chloride ions in flue-cured tobacco, increase the content of potassium ions in flue-cured tobacco, and make the content and ratio of chlorine and potassium in flue-cured tobacco more in line with high-quality Technical effects of flue-cured tobacco requirements. Now add the flue-cured tobacco potassium-increasing and chlorine-reducing agent for flue-cured tobacco prepared in Examples 1 to 8 and Comparative Examples 1 to 12 into the tobacco-specific growth regulator applicator disclosed in CN207369668U, and then put it on the flue-cured tobacco rod after topping for application. The application rate on the tobacco stems is 1.0g. Meanwhile, a control group (CK) not administered any accelerator was used as a control.

[0076] In this experimental exampl...

Abstract

The invention provides a potassium extraction and chlorine reduction agent for flue-cured tobacco as well as a preparation method and application of the potassium extraction and chlorine reduction agent and relates to the technical field of flue-cured tobacco planting. The potassium extraction and chlorine reduction agent for flue-cured tobacco is mainly prepared by mixing and compounding indoleacetic acid, gibberellins and epibrassinolide in wool fat. In long-term tobacco agriculture production practice, the inventor researches to find that in the case the indoleacetic acid, gibberellins andepibrassinolide are mixed and compounded in the wool fat to be applied to tobacco planting, compared with single dose use of the various components, the potassium extraction and chlorine reduction agent disclosed by the invention can achieve an obvious effect of regulating growth of the flue-cured tobacco, and can further achieve the effects of balancing absorption and distribution of the potassium ion and chloride ion in tobacco, reducing the chloride ion content in tobacco and improving the potassium ion content in the tobacco. Therefore, the content and ratio of chloride and potassium in the flue-cured tobacco meet the requirements of high-quality flue-cured tobacco, the yield and quality of the tobacco are improved, and the problems that the chloride ion content is high and the potassium ion content is low in the flue-cured tobacco leaf can be further effectively solved.

Description

technical field [0001] The invention relates to the technical field of flue-cured tobacco planting, in particular to a flue-cured tobacco potassium-decreasing agent and a preparation method and application thereof. Background technique [0002] Tobacco is the most widely planted foliar economic crop in the world, and my country's tobacco planting area and output rank first in the world. With people's concern about smoking and health issues and the increasingly fierce competition in international trade, the quality of tobacco and its products has gradually become the focus of competition in the tobacco market. The quality of tobacco and its products includes many aspects such as appearance quality, internal quality, physical characteristics, chemical composition and safety. [0003] As we all know, the potassium content in tobacco leaves can improve the appearance quality of tobacco leaves and the stability of chemical components, and at the same time help to improve the com...
