Problems solved by technology

However, in the process of tobacco planting and processing, a large amount of straw and waste tobacco leaves are produced. At present, there are few ways and low levels of comprehensive utilization of these tobacco wastes. Most of them are discarded as wastes or incinerated. waste and environmental pollution
[0003] However, the use of tobacco as a natural insecticide has been documented hundreds of years ago, but its application range is limited and its use method is very primitive

Embodiment 1

[0025] The preparation method of the tobacco waste-oriented agricultural functional composition of the present invention mainly includes the following steps:

[0026] 1) After fully drying 2KG of tobacco waste, pulverize it in a pulverizer, and then sieve it under 40-200 mesh to obtain dry and uniformly dispersed tobacco powder;

[0027] According to the botanical active ingredients and proportioning of some functional compositions given in Table 1,

[0028] 2) Mechanically stirring and mixing the active ingredient of plant origin with an appropriate amount of solvent to obtain a solution containing the active ingredient of plant origin;

[0029] 3) Spraying the solution containing the plant-derived active ingredient evenly into the smoke powder to obtain a dry powder composition;

[0030] Among them, the formula combination is various combinations of smoke powder (component A) and plant-derived active ingredients, and the plant-derived active ingredients are mainly selected ...

Embodiment 2

[0036] A method for preparing a tobacco waste-oriented agricultural functional composition, prepared according to the method of Example 1, comprising the following steps:

[0037] 1) After fully drying 2KG of waste tobacco waste, pulverize it in a pulverizer, and then sieve it under 50 meshes to obtain uniformly dispersed and dry smoke powder, and accurately weigh 1.7g of dry smoke powder for later use;

[0038] 2) Put 0.02 g of dibutyl succinate in an eggplant-shaped flask, then add 3 to 5 mL of dichloromethane, stir to mix evenly, and obtain a solution containing dibutyl succinate;

[0039] 3) Spray the solution containing dibutyl succinate evenly into the smoke powder and mix them uniformly to obtain the dry powder composition 3.

[0040] Add 0.1 g of sodium dodecylbenzenesulfonate, 0.08 g of sodium lauryl sulfate, and 0.1 g of carboxymethylcellulose sodium to the active ingredients of the agricultural functional composition prepared above, and grind evenly Get pesticides....

Embodiment 3

[0042] A method for preparing a tobacco waste-oriented agricultural functional composition, prepared according to the method of Example 1, comprising the following steps:

[0043] 1) After fully drying 2KG waste tobacco, pulverize it in a pulverizer, and then sieve it under 150 mesh to obtain evenly dispersed dry tobacco powder; accurately weigh 1.7g of dry tobacco powder for later use;

[0044] 2) Weigh 0.02g of carvacrol and 0.02g of dibutyl succinate, place them in an eggplant-shaped flask, then add 5-8mL of anhydrous methanol, stir to mix evenly, and obtain carvacrol and succinate A solution of dibutyl acid;

[0045] 3) Spray evenly the solution containing carvacrol and dibutyl succinate into the cigarette powder, and mix them uniformly to obtain dry powder composition 10 .

[0046] Finally, 0.08 g of rhamnolipid, 0.08 g of sodium dodecylbenzenesulfonate, and 0.1 g of sodium lignosulfonate were sequentially added to the active ingredients of the agricultural functional co...

Abstract

The invention discloses a tobacco waste oriented agricultural functional composition, and a preparation method and application thereof. The agricultural functional composition is prepared from plant source active ingredients and tobacco powder, wherein the weight ratio of the plant source active ingredients to the tobacco powder is 1 to (20 to 1000); and the plant source active ingredients are selected from one or several kinds of cnidium lactone, eugenol, carvacrol, mint oil, 1-(2-hydroxyphenyl)-1-butanone, dibutyl succinate, pyrethrins and neem extracts. The composition of the type takes tobacco waste and the plant source active ingredients as bases; a preparation process is simple and is easy to implement; raw materials are cheap and are easy to obtain; and the composition is an insecticidal functional composition with wide application prospect.

Description

technical field [0001] The invention relates to the comprehensive utilization of tobacco waste resources, in particular to a tobacco waste-oriented agricultural functional composition and its preparation method and application. Background technique [0002] Tobacco is one of the important economic crops in my country. Its planting area and output rank first in the world, and it occupies an important position in my country's agricultural economy. However, in the process of tobacco planting and processing, a large amount of straw and waste tobacco leaves are produced. At present, there are few ways and low levels of comprehensive utilization of these tobacco wastes. Most of them are discarded or incinerated as wastes, causing natural resources waste and environmental pollution. [0003] However, as early as hundreds of years ago, there were records of people using tobacco as a natural insecticide, but its application range was limited and its use method was very primitive. A...
