Embodiment 1

[0044] Component A: 6 parts of potassium fulvic acid, water solubility ≥ 90%, humic acid ≥ 60%.

[0045] Component B: 50 parts of urea, broken below 2.0mm.

[0046] Component C: 25 parts of urea phosphate, which is prepared by the following method: add crude phosphoric acid with a content ≥ 26% into crude phosphoric acid tank 1, add phosphate rock powder of 1-2% of the weight of crude phosphoric acid and stir, and then move into Add 0.5-1.5% sodium carbonate to crude phosphoric acid tank 2, stir, pressurize through a 0.5mm sieve to take the permeate, add urea with 50-70% weight of pure phosphoric acid, dissolve and react, pass through a 0.5mm sieve, heat and concentrate under negative pressure , cooled and crystallized, centrifuged and dried to obtain the product urea phosphate.

[0047] Component D: 16 parts of potassium chloride.

[0048]Component E: 3 parts of trace element complex, produced and prepared according to the following steps: add 500-600 parts by weight of wat...

Embodiment 2

[0051] Component A: Humic acid with water solubility ≥ 95% is 8 parts of fulvic acid potassium salt, humic acid content ≥ 60%; Component B: 45 parts of urea, crushed to less than 1.0mm; Component C: Potassium dihydrogen phosphate 20 parts; component D: 25 parts of potassium nitrate; component E: 2 parts of trace element complex.

[0052] Component E is formulated as follows: take 42, 21, 213, 128, 85 and 11 parts by weight of ferrous sulfate, copper sulfate, zinc sulfate, boric acid, manganese sulfate and ammonium molybdate respectively, and add 550 Parts by weight of water, heated to 70°C, first add 25 parts by weight of organic complexing agent EDTA and 60 parts by weight of citric acid into the reaction kettle and stir until dissolved, then add copper sulfate, zinc sulfate, ferrous sulfate, boric acid, manganese sulfate, Ammonium molybdate is added in order. When adding, add the last one after it is completely dissolved. After complete dissolution, the complexation reaction...

Embodiment 3

[0056] Component A: 6.5 parts of ammonium fulvic humate with water solubility ≥ 90% and humic acid content ≥ 70%; Component B: 45 parts of urea; Component C: a mixture of 10 parts of monoammonium phosphate and 10 parts of potassium dihydrogen phosphate ; Component D: 26 parts of potassium chloride; Component E: 2.5 parts of trace element complexes.

Abstract

The invention discloses a water soluble fertilizer and a production method thereof, in particular to a water soluble humic acid multi-element solid fertilizer and a production method thereof. The water soluble humic acid multi-element solid fertilizer is made by mixing water soluble humic acid, water soluble nitrogenous fertilizer, water soluble phosphorous fertilizer, water soluble potassic fertilizer and water soluble complex trace elements. Compared with the prior art, the water soluble humic acid multi-element solid fertilizer can reduce the transporting and packing cost, can be rapidly dissolved without agglomeration when in use, is applied along with water, and has the advantages of strong points, high nutrient content, complete nutrition, good water-solubility, combination of organic and inorganic matters as well as high effect of fertilizer and utilization rate. The utilization rate of product nitrogen reaches 60%, the utilization rate of phosphorus is 30-35%, and the utilization rate of potassium is 60-70%, so that the fertilizer application utilization rate is increased by more than 10% compared with the conventional fertilizer.

Description

technical field [0001] The invention relates to a water-soluble fertilizer and a production method thereof, in particular to a water-soluble humic acid multi-component solid fertilizer and a production method thereof. Background technique [0002] The application of fertilization with water technology in modern water-saving agriculture has significant effects of saving water, fertilizer and labor. However, fertilization with water has higher requirements for special fertilizers: the nutrient concentration in the fertilizer is high, it is completely soluble in water under field temperature conditions, can quickly dissolve in irrigation water, has good fluidity, and will not block filters and drippers. It contains less impurities, has little interaction with irrigation water, will not cause drastic changes in the pH of irrigation water, and is less corrosive to irrigation equipment systems. [0003] The water-soluble fertilizers currently on the market can be divided into gen...
