Embodiment 1

[0019] A kind of preparation method of herbicide, comprises the steps:

[0020] Glyphosate compound preparation steps: 600 parts by weight of glyphosate, 6 parts by weight of acifluorfen, 10 parts by weight of isooctyl fluroxypyr and 80 parts of sodium naphthalenesulfonate are mixed and carried out for ultra- Finely pulverized to form the glyphosate complex;

[0021] The preparation step of the attenuated additive: putting live housefly larvae and live leech into a pulping machine in equal parts to make a slurry, and then put it into a rotating interlayer fermenter for fermentation for 10 days, and obtained the attenuated additive by filtering and freeze-drying to make powder; as well as,

[0022] Mixing step: add 50 parts by weight of the attenuating additive to the glyphosate compound, and carry out gravity-free mixing in a pear-knife type gravity-free mixer to obtain the herbicide.

Embodiment 2

[0024] A kind of preparation method of herbicide, comprises the steps:

[0025] Glyphosate compound preparation steps: 1000 parts by weight of glyphosate, 10 parts by weight of fluorfen, 30 parts by weight of isooctyl fluroxyacetic acid and 100 parts by weight of sodium naphthalenesulfonate are mixed for ultra- Finely pulverized to form the glyphosate complex;

[0026] Preparation steps of the attenuated additive: put the living housefly larvae and the living leech in equal parts into a pulping machine to make a slurry, then enter the rotary interlayer fermenter for fermentation for 15 days, and filter and freeze-dry to make powder to obtain the attenuated additive; as well as,

[0027] Mixing step: add 100 parts by weight of the attenuating additive to the glyphosate compound, and carry out gravity-free mixing in a pear-knife-type gravity-free mixer to obtain the herbicide.

Embodiment 3

[0029] A kind of preparation method of herbicide, comprises the steps:

[0030] Glyphosate compound preparation steps: 800 parts by weight of glyphosate, 8 parts by weight of acifluorfen, 15 parts by weight of isooctyl fluroxypyr and 80 parts of sodium naphthalenesulfonate are mixed and carried out for ultra- Finely pulverized to form the glyphosate complex;

[0031] Preparation steps of the attenuated additive: put the living housefly larvae and the living leech in equal parts into a pulping machine to make a slurry, then enter the rotary interlayer fermenter for fermentation for 12 days, and filter and freeze-dry to make powder to obtain the attenuated additive;

[0032] Mixing step: add 60 parts by weight of the attenuating additive to the glyphosate compound, and carry out gravity-free mixing in a pear-knife-type gravity-free mixer to obtain the herbicide.

Abstract

The invention relates to an herbicide and a preparation method thereof. The method for preparing the herbicide comprises the following steps: preparing a glyphosate compound, namely mixing 600-1000 parts by weight of glyphosate, 6-10 parts by weight of fluoroglycofen, 10-30 parts by weight of fluroxypyr-mepthyl and 80-100 parts by weight of naphthalene sulfonic acid sodium salt, and performing superfine grinding on the mixture, thereby forming the glyphosate compound; preparing an attenuation additive, namely putting living musca domestica larva and living leeches with equal parts into a pulping machine to prepare pulp, fermenting the pulp in a rotary interlayer fermentation tank for 10-15 days, filtering and freeze-drying to prepare powder, thereby obtaining the attenuation additive; andmixing, namely adding the glyphosate compound into 50-100 parts by weight of the attenuation additive, and performing gravity-free mixing in a colter gravity-free mixer, thereby obtaining the herbicide.

Description

technical field [0001] The invention relates to a herbicide and a preparation method thereof. Background technique [0002] Glyphosate is often used in herbicides. Glyphosate is a broad-spectrum organophosphorus herbicide with excellent herbicidal performance. It is easily absorbed by plant leaves and transmitted to the whole plant. It has a high effect on annual and perennial weeds. active. However, glyphosate is very harmful to the human body. Not only is excessive consumption toxic, but a small amount of intake may also have long-term or chronic effects on health. Many studies at home and abroad have confirmed that glyphosate has varying degrees of damage to the liver and kidneys, mucous membranes (digestive tract and skin), nerves, respiratory and cardiovascular systems, and can cause cancer and teratogenicity in severe cases. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a herbicide and its preparation m...
