Plant growth regulator for improving upper leaf enlargement, nicotine reduction and potassium increase after topping

Abstract

The invention provides a plant growth regulator for improving upper leaf enlargement, nicotine reduction and potassium increase after topping. The plant growth regulator is prepared by taking by weight, 0.001-99.990% of gibberellic acid, 0.001-99.990% of heteroauxin, malonic acid, 0.001-99.990% of 2,4-d, 0.001-99.990% of dimethylformamide, 0.001-99.990% of nonylphenol polyoxyethylene ether and 0.001-99.990% of cyclohexanone, mixing the raw materials with uniformly stirring to prepare mixed solution and mixing, by weight, 60-70% of the mixed solution and 30-40% of potassium dihydrogen phosphate buffer solution with uniform stirring. By spraying the plant growth regulator to upper tobacco leaves, the growth period of a tobacco field is shortened, upper tobacco leaf enlargement, nicotine reduction and potassium increase can be promoted, tobacco leaf output is increased, and ashy tobacco leaves after baking of the upper tobacco leaves can be decreased. Besides, the tobacco leaves are slightly loose in structure, slightly dark, slightly high in gloss and sufficient in aroma, a single upper leaf is slightly heavy, the proportion of high-quality and medium-quality tobaccos is effectively increased, and accordingly economic income of tobacco growers is increased.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a plant growth regulator for improving upper leaf openings, reducing alkali and increasing potassium after topping. Background technique [0002] The low usability of the upper tobacco leaves is one of the main problems in the production of flue-cured tobacco in the tobacco leaf producing areas of the country today. Because the upper tobacco leaves are exposed to strong light and good ventilation, their dry matter accumulates a lot, and the leaves are not easy to open. Thick, dense leaf cells, dense and stiff tissue structure, less water content, slow maturation, and more ash on the tobacco leaves after roasting, dark color, high nicotine, starch, protein content, low reducing sugar and sugar alkali, Tobacco leaves have poor aroma, insufficient aroma, and strong irritation, etc., which lead to poor industrial usability and difficulties for the cigarette industry, t...

Because the upper tobacco leaves are exposed to strong light and good ventilation, their dry matter accumulates a lot, and the leaves are not easy to open. Thick, dense leaf cells, dense and stiff tissue structure, less water content, slow maturation, and more ash on the tobacco leaves after roasting, dark color, high nicotine, starch, protein content, low reducing sugar and sugar alkali, Tobacco leaves have poor aroma, insufficient aroma, and strong irritation, etc., which lead to poor industrial usability and difficulties for the cigarette industry, thus restricting the market operation of upper tobacco leaves
