Abstract

The invention discloses a field flue-cured tobacco regulator. By using water as a solvent, the field flue-cured tobacco regulator comprises the following raw materials in weight-volume ratio: 0.2-0.4 kg / L potassium nitrate, 0.2-0.4 kg / L potassium dihydrogen phosphate, 2.0-3.0 kg / L magnesium chloride, 5.0-6.0 g / L calcium nitrate, 0.5-1.5 g / L sodium borate, 0.2-0.6 kg / L potassium humate, 8-25 mg / L abscisic acid, 12-28 mg / L auxin, 0.3-1.8 mg / L brassinolide and a right amount of ethanol. The invention also discloses a preparation method and application of the regulator. The regulator disclosed by the invention can promote the field ripening enduring ability of the flue-cured tobacco, so that the tobacco has uniform maturity and yellowing, thereby enhancing the yield and quality of the flue-cured tobacco.

Description

Technical field [0001] The invention relates to the field of flue-cured tobacco regulators, and more specifically, to a field flue-cured tobacco regulator, and a preparation method and application thereof. Background technique [0002] Tobacco leaf maturity is closely related to tobacco leaf color, physiological and biochemical indicators, physical properties, chemical composition, smoking quality and safety. It is an important quality factor for cigarette companies to determine the quality of tobacco leaves. The maturity of tobacco leaves includes field maturity and graded maturity. Generally, the field maturity is good, and the tobacco leaves after correct curing and modulation have good graded maturity. [0003] The temperature in the mature season of tobacco leaves in southeastern my country is gradually increasing, and the rainfall is more concentrated. The field tobacco leaves in the environment of high temperature and high humidity can easily lead to high temperature and fo...
