Field rice planting middle-stage herbicide and preparation method thereof

Abstract

The invention relates to a field rice planting middle-stage herbicide. The field rice planting middle-stage herbicide is prepared from, by weight, 35-45 parts of acetochlor, 35-45 parts of atrazine, 15-19 parts of radix polygoni multiflori, 6-9 parts of fried platycodon roots, 15-18 parts of scorch-fried bombyx batryticatus, 12-14 parts of bulbus fritillariae cirrhosae, 5-7 parts of scorch-fried pericarpium papaveris, 9-14 parts of pear peels, 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 sugar refinery filter mud, 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 coprinus comatus, 80-90 parts of bean curds, 5-10 parts of ganoderma lucidum, 5-10 parts of salt, 5-10 parts of chicken essence, 5-10 parts of sesame oil, 200-210 parts of Ceylon black tea, 1,000-1,100 parts of boiled water, 100-110 parts of evaporated milk, 55-60 parts of white sugar, 20-25 parts of peanut kernels, 10-15 parts of milkvetch roots and 10-15 parts of radix angelicae sinensis. The prepared herbicide is specially used for removing field rice planting middle-stage weeds, the growth vigor of rice is not affected, the herbicide is dissolved in water and penetrates underground, and nutrition supply to the early-stage rice can be achieved.

Description

Technical field: [0001] The invention designs a field herbicide, and in particular relates to a field rice planting medium-term 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 rice and a preparation method thereof. [0004] The technical problem to be solved by the present invention i...
