Embodiment 1

[0024] First pour 800-1000 liters of water into the reaction kettle, turn on the heating device of the reaction kettle, keep the water temperature at 50-70°C, weigh 300 kg of humic acid raw materials into the reaction kettle and stir to dissolve, then add 200 kg of urea, and wait for the urea to dissolve , then add 110 kg of monoammonium phosphate and 140 kg of potassium nitrate, control the temperature at 50-70°C, and stir for 30-60 minutes. Soil essence is dissolved and fully mixed with the above materials, and finally add water to a total volume of 1500 liters, and cool to below 30°C to obtain the product.

Embodiment 2

[0026] First pour 400-500 liters of water into the reaction kettle, turn on the heating device of the reaction kettle, keep the water temperature at 50-70°C, weigh 200 kg of humic acid raw materials into the reaction kettle and stir to dissolve, then add 140 kg of urea, and wait for the urea to dissolve , then add 70 kg of monoammonium phosphate and 100 kg of potassium nitrate, control the temperature at 50-70°C, and stir for 30-60 minutes. Dissolve the earth essence and mix it well with the above-mentioned materials. Finally, add water to a total volume of 800 liters, and cool to below 30°C to obtain the product.

Embodiment 3

[0028] First pour 600-700 liters of water into the reaction kettle, turn on the heating device of the reaction kettle, keep the water temperature at 50-70°C, weigh 250 kg of humic acid raw materials into the reaction kettle and stir to dissolve, then add 170 kg of urea, and wait for the urea to dissolve , then add 90 kg of monoammonium phosphate and 120 kg of potassium nitrate, control the temperature at 50-70°C, and stir for 30-60 minutes. Soil essence is dissolved and fully mixed with the above materials. Finally, add water to a total volume of 1000 liters, and cool to below 30°C to obtain the product.

[0029] The invention has the advantages of simple manufacture, easy operation and high applicability, and solves the industrial production problems of the humic acid water-soluble fertilizer with single function, complex production process and various raw materials. The fertilizer has the advantages of improving soil physical and chemical properties, obvious and lasting fert...

Abstract

The invention discloses a humic acid-containing water-soluble fertilizer with a soil loosening function and a preparation method thereof. The preparation method comprises the step of dissolving and chelating the following raw materials in a reactor: high-quality polyacrylamide crystal which is an agricultural soil loosening agent, water-soluble humic acid, urea, monoammonium phosphate and potassium nitrate to produce the water soluble fertilizer which can be used for breaking through soil hardness, loosening soil, improving air permeability of soil, promoting microorganism activity of soil and enhancing fertilizer seepage force of soil and contains major elements, medium trace elements, humic acid and amino acid. The water-soluble fertilizer combines organic and inorganic matters, combines major elements and trace elements, and has the advantages of balancing nutrition, improving soil, improving the utilization ratio of nutrients and improving the yield and quality of crops.

Description

technical field [0001] The invention relates to a water-soluble fertilizer and a preparation method thereof, in particular to a humic acid-containing water-soluble fertilizer with soil loosening function and a preparation method thereof. Background technique [0002] Traditional fertilizers can easily cause fertilizer loss, eutrophication of water bodies, and damage to soil structure. As a new type of environmentally friendly fertilizer, water-soluble fertilizers avoid the shortcomings of traditional compound fertilizers. Water-soluble fertilizers are easy to use, can be sprayed, flushed, and can be used in combination with drip irrigation to improve fertilizer utilization. Water-soluble fertilizers also have advantages that traditional compound fertilizers do not have, that is, they can improve crop quality and reduce physiological diseases of crops. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a humic aci...
