Embodiment 1

[0016] Example 1 Prepare 1580 kg of anti-flocculation humic acid liquid water-soluble fertilizer.

[0017] The formula is: 125kg granular sodium humate (60% humic acid content), 200kg potassium dihydrogen phosphate, 350kg urea, 20kg 1% sodium alginate solution and 885kg reverse osmosis water.

[0018] The preparation method is: first dissolve 125kg granular sodium humate in 885kg reverse osmosis water, and stir for about 1 hour to fully dissolve, then slowly add potassium dihydrogen phosphate at a rate of about 10kg per minute, stirring while adding, when The solution becomes very viscous, viscosity ≥ 1000cp, when it is difficult to stir, stop adding potassium dihydrogen phosphate, after stirring for about half an hour, the fluidity of the solution is good, continue to add potassium dihydrogen phosphate, after adding potassium dihydrogen phosphate, continue to stir Dissolve it fully for about 1 hour, then add urea and sodium alginate solution with a mass fraction of 1% in sequ...

Embodiment 2

[0019] Example 2: Prepare 950 kg of deflocculating humic acid liquid water-soluble fertilizer.

[0020] The formula is: 70kg of sodium humate, 10kg of sodium alginate solution with a mass fraction of 1%, 210kg of urea, 120kg of potassium dihydrogen phosphate, and 540kg of reverse osmosis water.

[0021] The preparation method is as follows: first dissolve 70kg of sodium humate in 540kg of reverse osmosis water, and keep stirring until fully dissolved. The dissolution process takes about 1 hour. Then slowly add potassium dihydrogen phosphate, the addition rate is about 10kg per minute, stir while adding, when the solution becomes very viscous, viscosity ≥ 1000cp, when stirring is difficult, stop adding potassium dihydrogen phosphate, and wait for about half an hour to stir the solution After the fluidity is good, continue to add potassium dihydrogen phosphate. After the addition of potassium dihydrogen phosphate is complete, continue to stir for about 1 hour to fully dissolve i...

Embodiment 3

[0022] Example 3: Prepare 103.5 kg of anti-flocculation humic acid liquid water-soluble fertilizer.

[0023] The formula is: 9kg granular sodium humate (60% humic acid content), 12.5kg potassium dihydrogen phosphate, 22kg urea, 2kg sodium alginate solution with a mass fraction of 1%, and 58kg reverse osmosis water.

[0024] The preparation method is as follows: first dissolve 9kg granular sodium humate in 58kg reverse osmosis water, and stir for about 1 hour to fully dissolve, then slowly add potassium dihydrogen phosphate at a rate of about 10kg per minute, stirring while adding, when The solution becomes very viscous, viscosity ≥ 1000cp, when it is difficult to stir, stop adding potassium dihydrogen phosphate, after stirring for about half an hour, the fluidity of the solution is good, continue to add potassium dihydrogen phosphate, after adding potassium dihydrogen phosphate, continue to stir Dissolve it fully for about 1 hour, then add urea and sodium alginate solution wit...

Abstract

The invention discloses a deflocculating humic acid liquid water soluble fertilizer and a preparation method of the deflocculating humic acid liquid water soluble fertilizer. The deflocculating humic acid liquid water soluble fertilizer is prepared by the following raw materials in parts by weight: 0.06 to 0.09 parts of sodium humate, 0.01 to 0.03 parts of sodium alga acid solution with mass fraction of 1%, 0.21 to 0.23 parts of urea, 0.12 to 0.13 parts of monopotassium phosphate, and 0.54 to 0.58 parts of water. The preparation method comprises the following steps of: dissolving the sodium humate into the water, and agitating to fully dissolve; and then adding monopotassium phosphate, and agitating to fully dissolve; and finally adding the urea and the sodium alga acid solution in sequence, and agitating to fully dissolve so as to obtain the deflocculating humic acid liquid water soluble fertilizer, and subpackagging the obtained water soluble fertilizer to obtain the finished product. The deflocculating humic acid liquid water soluble fertilizer has high nutrient content, high stability in deflocculating, high water solubility, and high additional value.

Description

[0001] Technical field [0002] The invention relates to an anti-flocculation humic acid liquid water-soluble fertilizer and a preparation method thereof, and belongs to the technical field of agricultural fertilizers. Background technique [0003] As a green organic substance, humic acid is easy to obtain as raw material and does not produce secondary pollution. It has important application value in agriculture for improving soil, improving crop stress resistance, and improving the quality of agricultural products. With the development of my country's green environmental protection industry and the global low-carbon economy, the market space for humic acid technology and products is huge, and the new humic acid fertilizer industry will win better development. [0004] Most of the various humic acid fertilizer products currently on the market are divided into solid and liquid types. They are generally relatively low-end humic acid macronutrient fertilizers. They are general...
