Problems solved by technology

The impact of sodium humate and potassium humate on crops has been explained above. Although the ammonium salt of humic acid is more conducive to application, the ammonium humate that is currently commonly used is based on traditional mixed accumulation ammonization, Raymond mill grinding ammonization, etc. The method is to make humic acid ammonium, and the solubility of the final ammonium humic acid product is generally low, and the weeding effect is not good when used in combination with herbicides

Embodiment 1

[0026] The ammonium humate provided by the present invention and its preparation method are specifically illustrated by this embodiment. The preparation method of ammonium humate of the present invention comprises:

[0027] Process the weathered lignite into powder, determine the water content in it is about 20wt%, and the content of humic acid in the weathered lignite powder is about 55.21%;

[0028] The above-mentioned weathered lignite powder and ammonium bicarbonate are mixed in a reactor with a stirring and rolling device in a ratio of 70:30, driven by a 15-20KW motor, and welded at intervals on the circumference of the rotating shaft in the reactor. Stirring plates and rolling rollers keep the temperature of weathered coal powder and ammonium bicarbonate mixture at 16-35°C, stir and roll at a speed of 30r / min to obtain ammonium humate of the present invention, wherein the rolling rollers can be A rolling roller with a rolling pressure of 1.6 to 2 kg is applied on a unit...

Embodiment 2

[0037] Another ammonium humate provided by the present invention and its preparation method are specifically described through this example. The preparation method of the ammonium humate of the present embodiment comprises:

[0038] Process the weathered lignite into powder, determine the water content in it is about 20wt%, and the content of humic acid in the weathered lignite powder is about 55.21%;

[0039] After mixing the above-mentioned weathered lignite powder and ammonium bicarbonate in a ratio of 75:25, under the drive of a 15-20KW motor, use the stirring plate and rolling roller welded on the circumference of the rotating shaft at intervals to keep the weathered coal powder and ammonium bicarbonate The temperature of the mixture is 16-35°C, stirred at a speed of 30r / min, and rolled for 1.5hr to obtain the ammonium humate of the present invention, wherein the rolling roller is a rolling pressure that can apply 1.6-2kg rolling pressure per unit area The rollers, the a...

Embodiment 3

[0042] The herbicide complex provided by the present invention and its weeding method are specifically illustrated through this example.

[0043] A kind of herbicide complex, the ammonium humate obtained by the method of embodiment 1 and glyphosate are added with water and form, the content of described ammonium humate is 1g / L, and the content of described glyphosate is 5.5g / L .

[0044] The herbicide complex solution is sprayed with a sprayer to kill weeds. Use respectively the glyphosate aqueous solution 1 (the content of glyphosate is 5.5g / L) that does not add ammonium humate as contrast 1, and the glyphosate aqueous solution 2 (the content of glyphosate is 20g / L) that does not add ammonium humate L) As a control 2, the ammonium humate of the present invention is verified to promote the herbicide weeding effect.

[0045] Test location: Wugudi Village, Shulinzhao Town, Dalat Banner, Inner Mongolia.

[0046] The condition of the test field: it was set on a non-cultivated l...

Abstract

The invention provides humic acidic ammonium and a preparation method and application thereof. the preparation method of humic acidic ammonium comprises the following steps: mixing weathered coal and ammonium bicarbonate in a weight ratio of 2-4:1, and stirring and rolling at 16-35 DEG C to perform amination reaction and prepare humic acidic ammonium, wherein the the stirring rate is 30-40r / min, the stirring time is 1-2hr, and the rolling pressure is 1.6-2kg / cm<2>. The invention also provides the humic acidic ammonium prepared by the above method and the application thereof in the complex synergism of the herbicide. The invention also provides a herbicide complex which is the aqueous solution combined by the humic acidic ammonium and organophosphorus herbicide, and another herbicide complex which is the aqueous solution combined by the humic acidic ammonium, sulfonylurea herbicide and phenoxyacetic acid herbicide. The solubility of the humic acidic ammonium prepared by the method of the invention is more than 90%, and the humic acidic ammonium has various active components and can ensure that the herbicide effect of the herbicide complex is exerted.

Description

technical field [0001] The invention relates to ammonium humate and its preparation method and application, in particular to ammonium humate with a solubility of more than 90% and multiple active components, its preparation method and application. Background technique [0002] Humic acid is a macromolecular organic compound that exists widely in nature. It has the functions of increasing fertilizer efficiency, improving soil, stimulating crop growth, and improving the quality of agricultural products. However, humic acid in nature exists in a mineralized state combined with calcium, magnesium, etc., and humic acid in a mineralized state cannot be absorbed and utilized by plants. Only sodium salt, potassium salt and ammonium salt can be used to make it soluble. Salt can be used as a source of fertilizer. The sodium salt and potassium salt of humic acid have a strong stimulating effect on the root system of crops, and the concentration needs to be controlled during applicatio...
