Embodiment 1

[0035] This embodiment provides a method for preparing a fermented and decomposed material of sweet potato vines: crush the sweet potato vines to a particle size of less than 10 mm, add water and mix evenly, the quality of the water is 0.5 times the quality of the sweet potato vines, add hydrogen peroxide until no bubbles are generated, add Mix EM strain and enzyme bacteria, urea and molasses evenly. The mass of EM strain and enzyme bacteria is 2% of the mass of sweet potato vine (the mass ratio of EM strain and enzyme bacteria is 1:3), and the quality of urea is sweet potato. 0.5% of the mass of the vine, the mass of the molasses is 5% of the mass of the sweet potato vine, fermented at room temperature to decompose, turn the heap and stir every 3 days during the fermentation process, and dry to a moisture content of less than 30% after decomposing, that is, the sweet potato vine is fermented Decomposed material.

Embodiment 2

[0037] This embodiment provides a method for preparing a wheat bran fermented and decomposed material: crush the wheat bran to a particle size of less than 10 mm, add water and mix evenly, the quality of the water is 1.5 times that of the wheat bran, add hydrogen peroxide until no bubbles are generated So far, add EM strain and enzyme bacteria, ammonium sulfate and molasses, mix well, the quality of EM strain and enzyme bacteria is 0.5% of the quality of wheat bran (the mass ratio of EM bacteria and enzyme bacteria is 1:1), The mass of ammonium sulfate is 2% of the mass of wheat bran, and the mass of molasses is 1% of the mass of wheat bran, fermented at room temperature until decomposed, during the fermentation process, the heap is turned and stirred every 2 days, and dried to a moisture content of less than 30%, namely, the fermented and decomposed material of wheat bran is obtained.

Embodiment 3

[0039] This embodiment provides a method for preparing a fermented and decomposed material of apple tree leaves: crush the apple tree leaves to a particle size of less than 10 mm, add water and mix evenly, the quality of the water is 1 times the quality of the apple tree leaves, add hydrogen peroxide until no bubbles are generated So far, add EM strain and enzyme bacteria, urea and molasses, mix evenly, the mass of EM strain and enzyme bacteria is 1% of the mass of apple tree leaves (the mass ratio of EM strain and enzyme bacteria is 3:1), urea The mass of the molasses is 1.5% of the mass of the leaves of the apple tree, and the mass of the molasses is 2.5% of the mass of the leaves of the apple tree. It is fermented at room temperature until it is decomposed. During the fermentation process, the heap is turned and stirred every 2 days. After decomposing, it is dried to a moisture content of less than 30%. , that is, the fermented and decomposed material of apple tree leaves is...

Abstract

The invention relates to the technical field of pesticide residue reduction, in particular to a composition for reducing pesticide content of plants and a preparation method thereof. The composition for reducing the pesticide content of the plants comprises the following components in percentage by mass: 30%-40% of fulvic acid, 30%-42% of a fermented and decomposed material of plant residues, 0.01%-1% of a chelating agent, 0.01%-1% of an organic silicon surfactant, 10%-20% of tomato stems and leaves, 5%-10% of tobacco stems and 5%-10% of castor stems and leaves. According to the invention, the composition for reducing the pesticide content of the plants can stably and efficiently reduce the content of organic nitrogen, organic phosphorus and pyrethroid pesticides in the plants, nutrients can be provided for the plants to promote the growth of the plants, and meanwhile, the tomato stems and leaves, the tobacco stems and the castor stems and leaves in the composition have the effect of expelling insects and can further reduce the usage amount of pesticides. The composition for reducing the pesticide content of the plants is easy to store, convenient to use and suitable for popularization and application, and has very high social value.

Description

technical field [0001] The invention relates to the technical field of reducing pesticide residues, in particular to a composition for reducing pesticide content in plants and a preparation method thereof. Background technique [0002] With the development and progress of society, the use of organic compound pesticides is increasing, and their residues in plants are also increasing, which poses an increasing threat to human health. Organic compound pesticides mainly include organochlorine, organophosphorus, carbamate, organonitrogen, organosulfur and pyrethroid pesticides. Organic nitrogen pesticides are nitrogen-containing organic compounds used to control plant diseases, insects and weeds. There are many varieties of such pesticides and a wide range, including insecticides, fungicides and herbicides. In addition to stomach poisoning and contact killing, some products also have strong internal absorption properties. Organic nitrogen pesticides are mainly carbamate compou...
