Abstract

The invention discloses a herbicide used for a wheat field. The herbicide is characterized by being composed of, by weight, 3-15 parts of sodium chlorate, 4-6 parts of sodium borate, 5-15 parts of nitrophenol, 8-17 parts of amide herbicides, 4-6 parts of aqueous suspension emulsion and 10-20 parts of phenoxy herbicides. According to the herbicide used for the wheat field, the formula is simple, material taking is easy, the advantages of the phenoxy herbicides and amide herbicides are integrated, the characteristics of a conductive herbicide and a hormone herbicide are considered, and the economic benefits of planting can be increased. The preparation method is simple and easy to operate, and the herbicide will not pollute the environment during usage, prevents water eutrophication, improves the weed-removal effect and can guarantee that crops will not be hurt by weeds in the whole growth period through one-time chemical usage.

Description

technical field [0001] The invention belongs to the field of wheat planting, and in particular relates to a herbicide for wheat and a preparation method thereof. Background technique [0002] Wheat is the general name of wheat plants. It is a monocotyledon and a gramineous plant widely planted all over the world. The caryopsis of wheat is one of the staple foods of human beings. After being ground into flour, it can be used to make bread, steamed buns, biscuits, and noodles. and other foods; after fermentation, it can be made into beer, alcohol, liquor (such as vodka), or biofuel. Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin, vitamin A and vitamin C, etc. [0003] At present, in wheat planting, chemical pesticides and herbicides are usually used to prevent weeds. When the environmental pollution caused by the large-scale use of chemical fertilizers and pesticides is becoming more and more serious, at the same time, chemical pe...
