Embodiment 1

[0024] see figure 1 , the embodiment of the present invention provides a kind of method of producing potassium humate, the method comprises:

[0025] 101: Pulverize the raw material containing humic acid to 20 mesh, add it to the reaction kettle, add 2 molar concentration of sulfuric acid under stirring with water, so that the pH value is in the range of 3.0-3.2.

[0026] Wherein, the raw material containing humic acid is weathered coal, lignite, or carbon mud; in order to ensure the fineness of the raw material containing humic acid, the raw material containing humic acid is crushed to at least 20 meshes. The reaction kettle can be an enamel reaction kettle or a stainless steel reaction kettle. Moreover, during the process of adding sulfuric acid with 2 molar concentration, the pH value of the reactant can be tested by pH test paper, and the pH value can be controlled in the range of 3.0-3.2.

[0027] 102: Add potassium permanganate under stirring, and raise the temperature...

Embodiment 2

[0034] see figure 2 , the embodiment of the present invention provides a kind of method of producing liquid fertilizer, and the method utilizes the potassium humate produced in embodiment 1 to produce liquid fertilizer, and the method comprises:

[0035] 201: Add 700 kg of water, 180 kg of ammonium dihydrogen phosphate and 200 kg of potassium dihydrogen phosphate into the reactor, and stir to dissolve the ammonium dihydrogen phosphate and potassium dihydrogen phosphate.

[0036] Wherein, the reaction kettle can be an enamel reaction kettle or a stainless steel reaction kettle.

[0037] 202: Slowly add 150 kg of potassium hydroxide into the reaction kettle under stirring.

[0038] At this point, the reaction generates heat to form a homogeneous liquid.

[0039] 203: Add 90 kg of urea into the reaction kettle.

[0040] 204: Add 120 kg of potassium humate into the reaction kettle under stirring to generate a homogeneous liquid to obtain a liquid fertilizer.

[0041] Wherein,...

Embodiment 3

[0044] The embodiment of the present invention provides a kind of liquid fertilizer, and this liquid fertilizer utilizes the potassium humate produced in embodiment 1 and the production method of embodiment 2 to obtain, and the active ingredient contained in this liquid fertilizer is:

[0045] Humic acid: 80-90 g / L; Phosphorus: 210-230 g / L; Potassium: 200-220 g / L; Nitrogen: 60-70 g / L.

[0046] The liquid fertilizer described in the embodiment of the present invention is produced by potassium humate. The total content of nitrogen, phosphorus and potassium in the liquid fertilizer reaches more than 450 grams per liter, and the pure humic acid reaches 80 grams per liter. The content of active ingredients is high and can promote photosynthesis. Function and root development; the liquid fertilizer does not contain any synthetic growth regulators, non-toxic and pollution-free, stable performance, and can be stored for a long time; the fertilizer effect is stable, quick and effective,...

Abstract

The invention discloses methods for producing humic acid potassium and liquid fertilizer, belonging to the technical field of agriculture. The method for producing humic acid potassium comprises the steps: smashing raw materials of humic acid into at least 20 meshes, adding water, blending, adding vitriol with the concentration of 2 mol so that the pH value is within the range of 3.0-3.2; adding potassium permanganate while blending, and rising the temperature to 55-60 DEG C; blending and reacting for at least 2h, adding potassium hydroxide liquid with the concentration of 35 percent, and rising the temperature to 70-80 DEG C so that the pH value is within the range of 8.5-9.5; reacting for at least 0.5h, taking out supernatant liquor of a reacting substance, and drying to obtain humic acid potassium. The method for producing liquid fertilizer comprises the steps: dissolving 18 parts by weight of monoammonium phosphate and 20 parts by weight of monopotassium phosphate into 70 parts by weight of water; adding 15 parts by weight of potassium hydroxide while blending; adding 9 parts by weight of carbamide; and adding 12 parts by weight of humic acid potassium while blending and producing liquid fertilizer. The invention also discloses the liquid fertilizer.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a method for producing potassium humate and liquid fertilizer and the liquid fertilizer. Background technique [0002] Fertilizer is the food of crops. With the development of agricultural technology, fertilizer has developed from farmyard manure and solid fertilizer to liquid fertilizer. Liquid fertilizer is a new type of high-efficiency compound fertilizer, which has a series of advantages, such as: no dust and other pollution during production, transportation and use; no caking; can be mixed with most pesticides and herbicides; It can be used in a variety of ways, such as foliar spray or irrigation. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] The content of effective components such as nitrogen, phosphorus and potassium in the existing liquid fertilizer is low, an...
