Herbicide used in early period of field rice planting and preparation method of herbicide

Abstract

The invention provides herbicide used in the early period of field rice planting. The herbicide is prepared from, by weight, 35-45 parts of acetochlor, 35-45 parts of atrazine, 15-19 parts of rhizoma atractylodis, 6-9 parts of burnt cortex phellodendri, 15-18 parts of rhizoma pinelliae, 12-14 parts of semen coicis, 5-7 parts of radix achyranthis bidentatae, 9-14 parts of waxgourd seeds, 30-50 parts of fructus momordicae, 50-60 parts of vinegar, 50-60 parts of peanuts, 50-60 parts of malt sugar, 1000-1200 parts of green tea, 70-80 parts of orange juice, 50-70 parts of tomato juice, 5-10 parts of rhizoma polygonati odorati, 200-220 parts of soybeans, 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 and 10-15 parts of MaiBaoSu. The herbicide used in the early period of field rice planting and a preparation method of the herbicide have the advantages that the prepared herbicide is professionally used for removing weeds in the early period of field rice, the upward trend of the rice is not influenced, meanwhile the herbicide is permeated into the ground after being dissolved in water, and nutrient supply to the rice in the early period can be further achieved; by means of the method, plant diseases and insect pests are reduced, high quality and high yield are achieved, the yield of the rice is greatly raised, and the rice produced through the method is plumpy in particle, rich in nutrient and applicable to popularization.

Description

Technical field: [0001] The invention designs a field herbicide, in particular to a field rice planting early 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 field rice planting early herbicide and a preparation method thereof. [0004] The technical problem to be solved by the present invention is realized by the f...
