Nicotine-reducing potassium-increasing agent for cured tobacco and application method thereof

Abstract

The invention discloses a nicotine-reducing potassium-increasing agent for cured tobacco and an application method thereof. The nicotine-reducing potassium-increasing agent for cured tobacco is composed of the components by weight: 0.2-3% of arginine, 0.3-7% of methionine, 2-7% of sodium silicomolybdate, 2-10% of P2O5, 2-9% of K2O, 0.01-1% of EDDHA (ethylenediamine di-2-hydroxyphenyl acetic acid)-Fe, 0.01-3% of EDTA (ethylenediamine tetraacetic acid)-Zn, 0.01-2% of EDTA-Mn, 0-2% of rapin lactone, 0-15% of sulfosalicylic acid, 0.1-10% of salicylic acid and the balance of water. A nicotine-reducing potassium-increasing composition for cured tobacco contains at least one of rapin lactone or 5-sulfosalicylic acid. According to the nicotine-reducing potassium-increasing agent for cured tobacco, nutritive elements, microelements for helping plants to absorb the nutritive elements and plant growth regulators for regulating plant growth are reasonably mixed, so that the element absorption and distribution of the tobacco are more balanced, the nicotine content of the cured tobacco is reduced, the potassium content of the cured tobacco is increased, the contents and ratio of nicotine and potassium in the cured tobacco conform to the requirements of high-quality cured tobacco, and the yield and quality of tobacco leaf are improved.

Description

technical field [0001] The invention belongs to the technical field of plant growth regulators, and in particular relates to an alkali-reducing and potassium-increasing agent for flue-cured tobacco and a use method thereof. Background technique [0002] Tobacco is an economic crop for leaves, and the quality requirements for tobacco leaves are particularly high. At present, due to the excessive amount of fertilization, the current tobacco leaves in my country have problems such as low overall quality, insufficient aroma, insufficient aroma concentration, high nicotine content, high starch content, and poor usability, especially in the production of flue-cured tobacco leaves. High, the potassium content of flue-cured tobacco leaves is insufficient, which affects the availability of tobacco leaves. The quality of this tobacco leaf has affected the production and export of high-quality cigarettes in my country, and also damaged the economic interests of tobacco farmers. At pre...

AI Technical Summary

Problems solved by technology

However, it has limited effect on regulating the reduction of nicotine content and increasing the absorption of potassium

[0003] At present, there is no overall technical solution suitable for flue-cured tobacco that can reduce alkali and increase potassium, make the content and ratio of nicotine and potassium in flue-cured tobacco more in line with the requirements of high-quality flue-cured tobacco, and effectively ensure the yield of tobacco leaves
