Herbicide used in middle period of field corn planting and preparation method of herbicide

Abstract

The invention provides herbicide used in the middle period of field wheat planting. The herbicide is prepared from, by weight, 35-45 parts of acetochlor, 35-45 parts of atrazine, 15-19 parts of roasted flos farfarae, 6-9 parts of stir-fried radix platycodonis, 15-18 parts of cortex acanthopanacis, 12-14 parts of bulbus fritillariae cirrhosae, 5-7 parts of roasted pericarpium papaveris, 9-14 parts of pericarp of bretschneider pear, 30-50 parts of fructus momordicae, 50-60 parts of vinegar, 50-56 parts of straw, 10-15 parts of plant ash, 10-20 parts of filter mud from a sugar refinery, 1-2 parts of probiotics, 10-15 parts of diafenthiuron, 10-15 parts of methomyl, 10-15 parts of pyridaben, 10-15 parts of MaiBaoSu, 60-70 parts of dictyophora indusiata (Vent.ex Pers.)Fisch. mushroom, 80-90 parts of Chinese dates, 5-10 parts of gallus gallus domesticus brisson, 5-10 parts of salt, 5-10 parts of chicken extract, 5-10 parts of sesame oil, 200-210 parts of ceylon tea, 1000-1100 parts of boiled water, 100-110 parts of evaporated milk, 55-60 parts of white sugar, 20-25 parts of groundnut kernels, 10-15 parts of radix astragali and 10-15 parts of radix angelica sinensis. The prepared herbicide is professionally used for removing weeds in the middle period of field corn, the upward trend of the corn is not influenced, meanwhile the herbicide is permeated into the ground after being dissolved in water, and nutrient supply to the corn in the middle period can be further achieved.

Description

Technical field: [0001] The invention designs a field herbicide, in particular to a field corn planting mid-stage herbicide and a preparation method thereof. Background technique: [0002] Chemical weeding is the development trend of modern agriculture. Chemical herbicides have been widely used in most of my country's farmlands at present, which has produced great economic benefits. There are shortcomings in herbicide varieties. After many years of herbicide use, most weeds have developed resistance to varying degrees. At the same time, the existing herbicides are not based on the corresponding weeding for the early, middle and late crop growth. The weeding effect is average. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a mid-planting herbicide for field corn and a preparation method thereof. [0004] The technical problem to be solved by the present invention is realized by ...
