Weeding powder for preventing tillage deterioration and preparation method thereof

Abstract

The invention relates to a weeding powder for preventing tillage deterioration. The weeding powder is prepared from the following medicinal materials in parts by weight: 70 to 80 parts of sapindus episperm extracting solution, 65 to 75 parts of Japanese glorybower, 53 to 63 parts of syringa oblate, 46 to 56 parts of petroleum ether, 39 to 49 parts of walnut tree root, 31 to 41 parts of medicago sativa, 24 to 34 parts of triethanolamine, 18 to 28 parts of fragrant eupatorium herb extracting solution, 10 to 20 parts of calcium acetate, 10 to 20 parts of compound enzyme, 7 to 17 parts of vitexicar-pin, 6 to 16 parts of potassium dodecyl sulfate, 5 to 15 parts of maltodextrin, 3 to 13 parts of parthenium hysterophorus, 1 to 10 parts of secondary alkyl sodium sulfonate, 2 to 12 parts of karaya gum and 3 to 13 parts of common nepenthes. The invention also discloses a preparation method. The weeding powder has the advantages that by compounding the raw materials, the water solubility is good; the weeding powder can be singly used or compounded with other weeding agents, the efficiency is high, the environment-friendly effect is realized, and the easiness in producing resistance is avoided; the weeding powder can be completely degraded in soil, and the safety to crops is good.

Description

Technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicide powder for protecting farming deterioration and a preparation method thereof. Background technique [0002] Herbicides mainly inhibit, hinder or interfere with various important physiological and biochemical processes of plants, so that weeds cannot grow normally and die. In recent years, various herbicides have been used in large quantities in our country. The use of herbicides has reduced costs for farmers, reduced labor, and increased productivity. It is a manifestation of the progress of modern agricultural production. However, due to blind abuse, large or excessive use of various herbicides not only affects agricultural production and crop yields, but also brings serious negative effects to the ecological environment, such as water and soil pollution, reduced soil detoxification capabilities, and local microclimate damage. . [0003] With the expansion of the imple...

AI Technical Summary

Problems solved by technology

[0006] 3. The increase in the amount of herbicides has increased the degree of environmental pollution to a certain extent;

[0007] 4. Serious occurrence of weeds in conservation tillage farmland reduces grain production and lowers commerciality

[0012] 1. The broad-spectrum effect of control is not enough, and the control ability is not strong, especially the control effect on the underground part of Cyperus rotundum and Sorrel safflower;

[0013] 2. The dosage is large and the utilization rate is low, resulting in a large amount of residue, which is harmful to crops, soil, humans and animals;

[0014] 3. Certain weeds have developed resistance to a single dosage form;

[0015] 4. It is easy to cause drug injury;

[0016] 5. There are precedents for microencapsulating pesticides in the existing technology, but the disadvantages are that the encapsulation rate is not high, the degree of miniaturization and fluidity of the prepared microcapsules is insufficient, and the preparation process is not optimized, etc.
