Problems solved by technology

[0006] Aiming at the problems that existing tobacco leaves cannot be picked in the face of continuous rainy weather, mature leaves tend to turn green, delay the picking period, and increase the burden on tobacco farmers, the present invention provides a tobacco leaf surface spraying agent and the application of rutin, which can be added by adding reed Ding (C 27 h 30 o 16 ), naringin (C 27 h 32 o 14 ) and thiophanate-methyl (C 12 h 14 N 4 o 4 S 2 ) and a variety of nutrients to prevent tobacco leaves from turning green. At the same time, naringin has a strong ultraviolet absorption peak at 282nm to maintain the stability of chlorophyll in tobacco leaves and prevent it from over-ripe and easy to dry and black after baking. situation, maintaining a high baking quality

Embodiment 1

[0046] The preparation method of tobacco leaf surface spraying agent of the present invention, its steps are:

[0047] (1) Weigh 10 parts by mass (each part is 20g in this example) of thiophanate-methyl, put it into 100 parts of water, and stir to obtain an aqueous solution of thiophanate-methyl; the stirring time is 7 min, and the The stirring at the place is mainly for mixing evenly, and the requirement for stirring time is not high;

[0048] (2) Weigh 9 parts of alkylphenol polyoxyethylene ether and 6 parts of dimethyl sulfoxide according to the mass parts into the aqueous solution of thiophanate-methyl prepared in step (1), and stir while adding, Stirring time is 14 min, obtain A mixed solution;

[0049] (3) Weigh 15 parts of zinc sulfate, 8 parts of boric acid and 5 parts of potassium dihydrogen phosphate into the A mixed solution prepared in step (2) according to the parts by mass, and stir for 17 minutes to obtain the B mixed solution;

[0050] (4) Heat the B mixed so...

Embodiment 2

[0055] With Example 1, the difference is that the composition and mass parts of each material are: zinc sulfate: 10 parts; boric acid: 15 parts; potassium dihydrogen phosphate: 3 parts; rutin: 2 parts; dimethyl sulfoxide: 4 parts; naringin: 10 parts; thiophanate-methyl: 15 parts; alkylphenol polyoxyethylene ether: 3 parts; water: 200 parts; the stirring time in step (1) is 5 minutes; step (2) The stirring time in step (3) is 20 min; the stirring time in step (3) is 20 min; in step (4), the B mixed solution prepared in step (3) is heated to 40°C, and naringin is put into step (3) In the prepared B mixed solution, stir for 3 minutes, and keep the temperature of the solution at 40+3°C during the stirring process (because the ambient temperature is fluctuating, here indicates the fluctuation range, that is, the temperature is always between 40-43°C); step ( 5) Stir until the temperature of the mixed solution drops to 20°C and stop stirring.

[0056] Select 800 pieces of mature to...

Embodiment 3

[0058] Same as Example 1, the difference is that the composition and mass parts of each material are: zinc sulfate: 20 parts; boric acid: 10 parts; potassium dihydrogen phosphate: 10 parts; rutin: 1 part; dimethyl sulfoxide: 3 parts; naringin: 5 parts; thiophanate-methyl: 13 parts; alkylphenol polyoxyethylene ether: 6 parts; water: 150 parts; the stirring time in step (1) was 13 min; step (2 ) was 20 min; the stirring time in step (3) was 5 min; in step (4), the mixed solution of B prepared in step (3) was heated to 50°C, and naringin was added to step ( 3) In the prepared B mixed solution, stir for 4 minutes, keep the temperature of the solution at 50-2°C during the stirring process; stir in step (5) until the temperature of the mixed solution drops to 25°C and stop stirring.

[0059] Select 600 pieces of mature tobacco leaves in a plot on a rainy day, and measure the relative value of chlorophyll content, that is, the SPAD value. The result is that the SPAD value is between ...

Abstract

The invention discloses application of a tobacco leaf blade spraying agent and rutin and belongs to the field of production of pesticides. The tobacco leaf blade spraying agent comprises the following components in parts by mass: 10-20 parts of zinc sulfate, 8-15 parts of boric acid, 3-10 parts of monopotassium phosphate, 1-3 parts of rutin, 3-6 parts of dimethyl sulfoxide, 5-10 parts of naringin, 10-15 parts of thiophanate-methyl, 3-9 parts of alkylphenol polyoxyethylene ether and 100-200 parts of water. By adding rutin (C27H30O16), naringin (C27H32O14) and thiophanate-methyl (C12H14N4O4S2) as well as multiple nutrient elements are added for preventing revival phenomenon of tobacco leaves, and naringin has a strong ultraviolet absorption peak at the wavelength of 282nm, so that stable chlorophyll in the tobacco leaves is maintained, postmaturity of the tobacco leaves is prevented, the tobacco leaves can not be dried up or turn black after being baked, and high baking quality is maintained.

Description

technical field [0001] The invention belongs to the field of pesticide production, and in particular relates to a tobacco leaf surface spraying agent and the application of rutin. Background technique [0002] Tobacco leaves are raw materials for the tobacco industry. They are annual herbs, Solanaceae, with a plant height of about 1 meter. The petiole is not obvious or has a wing-like stalk. When touched by hand, the leaves are sticky, the panicle is terminal, the calyx is tube-shaped, the corolla is funnel-shaped, shaped like a bugle, and the end is pink. Capsule, yellow-brown seed, native to South America, cultivated all over the world. [0003] To prepare tobacco leaves into cigarettes, it needs to be picked after the tobacco leaves mature, and then baked. The general characteristics of tobacco leaf maturity are: the color (main color) changes from green to yellow-green; the veins become white and shiny; the leaves droop, naturally curved and arched, the leaf edge rolls...
