Embodiment 1

[0019] Configuration and use of embodiment 1 regulator A

[0020] Weigh 45g of potassium citrate, 15g of calcium chloride, 15g of potassium dihydrogen phosphate and dissolve in 15L of water, adjust pH=5.5-6.5 with dilute hydrochloric acid; weigh 1.5g of forchlorfenuron, 1.5g of indole acetic acid, 1.5g of water Dissolve cylic acid and 1.5 g of phenyl salicylate in 100 mL of ethanol, then pour it into the aqueous solution and mix well to obtain conditioner A.

[0021] In a normal-growing field of Yunyan 87 in a production area in Hubei Province, one mu was selected to spray the upper six leaves with conditioner A on a sunny morning after the middle leaves were harvested, and the adjacent one-mu field was used as a blank control.

Embodiment 2

[0022] Configuration and use of embodiment 2 regulator B

[0023] Weigh 90g of potassium citrate, 30g of calcium chloride, 30g of potassium dihydrogen phosphate and 90g of potassium chloride and dissolve them in 30L of water, adjust the pH to 5.5-6.5 with dilute hydrochloric acid; weigh 3g of forchlorfenuron, 3g of indole acetic acid, Dissolve 3g of salicylic acid and 3g of phenyl salicylate in 200mL of ethanol, then pour it into the aqueous solution and mix well to obtain conditioner B.

[0024] In a field with normal growth of Yunyan 87 in a certain producing area in Hubei Province, one mu was selected for foliar spraying with conditioner B on a sunny morning after topping, and the adjacent one mu of field was used as a blank control.

Embodiment 3

[0025] Example 3 Configuration of Modulators C and D and their use

[0026] Weigh 45g of potassium citrate, 15g of calcium chloride, 15g of potassium dihydrogen phosphate and 45g of potassium chloride and dissolve them in 30L of water, adjust the pH to 5.5-6.5 with dilute hydrochloric acid; weigh 1.5g of forchlorfenuron, 1.5g of indole Acetic acid, 1.5 g of salicylic acid and 1.5 g of phenyl salicylate were dissolved in 100 mL of ethanol, then poured into the aqueous solution and mixed well to obtain conditioner C.

[0027] Weigh 15g of potassium citrate, 5g of calcium chloride, 5g of potassium dihydrogen phosphate and 15g of potassium chloride and dissolve them in 10L of water, adjust the pH to 5.5-6.5 with dilute hydrochloric acid; weigh 0.5g of forchlorfenuron and 0.5g of indole Acetic acid, 0.5 g of salicylic acid and 0.5 g of phenyl salicylate were dissolved in 50 mL of ethanol, then poured into the aqueous solution and mixed well to obtain conditioner D.

Abstract

The invention relates to an upper leaf upgrading field physiological regulator, as well as a preparation method and using method thereof. The physiological regulator comprises a component (I) and a component (II), wherein, in mass concentration, the component (I) is prepared from forchior fennron, heteroauxin, salicylic acid and phenol salicylate, and the component (II) is prepared from potassiumcitrate, calcium chloride and monopotassium phosphate. The physiological regulator can be used for regulating the metabolism of reactive oxygen of upper leaves under intensive light, relieving high-temperature intensive light and other adversity stresses, promoting upper leaf field unfolding, reducing the content of nicotine, regulating the sugar-alkali ratio and potassium content, increasing thecontent of flavoring substance of upper leaves and improving the sensory evaluation quality of upper leaves.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation, and in particular relates to a field physiological regulator for improving the quality of upper tobacco leaves and a preparation method and application method thereof. Background technique [0002] The upper leaves make a great contribution to the overall yield and quality of flue-cured tobacco, accounting for 30%-45% of the total yield of the whole plant. The upper leaves with good quality play an important role in the formulation of modern hybrid cigarettes and low-tar flue-cured tobacco leaf groups. It plays a leading role and contributes greatly to the flavor and style of cigarettes. However, in the current agricultural production, problems such as poor upper leaves, tight organizational structure, and uncoordinated internal chemical components are prominent, resulting in low availability and high inventory pressure. The uncoordinated chemical composition is mainly manifested in ...
