Problems solved by technology

[0002] At present, in order to reduce the cost of many humic acid liquid fertilizers in China, the humic acid is mostly sodium humate, which will pollute the environment in the remaining residue after extraction.
[0003] In addition, many humic acid fertilizers are mainly based on humic acid and macroelements, ignoring the addition of several trace elements
At present, farmers pay more attention to the use of macronutrient fertilizers. Trace elements are ignored because of their small amo

Embodiment 1

[0031] Take 70kg of weathered coal containing more than 50% humic acid, add 480kg of water and 12kg of 90% potassium hydroxide, react for 3 hours at a temperature of 50-60 degrees, and centrifugally filter on a centrifuge at 3000 rpm to extract humic acid Potassium 500kg; add 130kg of urea, 140kg of potassium dihydrogen phosphate, 5kg of boric acid, 1kg of ammonium molybdate; then dissolve 13kg of complexing agent ethylenediaminetetraacetic acid with 151kg of water, then add 7kg of ferrous sulfate, 5kg of copper sulfate, 4kg of Zinc sulfate, 20kg magnesium sulfate, 20kg calcium nitrate, 4kg manganese sulfate, heated to dissolve. All the materials were mixed and then emulsified, and the finished product was obtained after emulsifying for 4 hours.

Embodiment 2

[0033] Take 70kg of peat containing more than 60% humic acid, add 330kg of water and 13kg of 90% potassium hydroxide, react for 4 hours at a temperature of 50-60 degrees, and centrifugally filter on a centrifuge at 3000 rpm to extract potassium humate 320kg; add 80kg of dissolved urea, 50kg of potassium dihydrogen phosphate, 12kg of boric acid, and 2kg of ammonium molybdate; add 25kg of complexing agent ethylenediaminetetraacetic acid and 250kg of water to dissolve, then add 110kg of ferrous sulfate and 42kg of copper sulfate , 32kg zinc sulfate, 30kg magnesium sulfate, 30kg calcium nitrate, 17kg manganese sulfate, heated and dissolved. All the materials were mixed and then emulsified, and the finished product was obtained after emulsifying for 4 hours.

Abstract

The invention relates to a manufacture method for water solubility fertilizer containing humus acid. It includes the following steps: adding water and raw material, and KOH as extracting agent, keeping temperature at 50-60 degree centigrade, distilling for 1-2 hours, taking centrifuging, filtering potassium humate, exhausting residue, dissolving N, P, K, and B, dissolving complex agent and adding Ca, Mg, Cu, Fe, Zn, and Mn, heating to dissolving; mixing the materials gained from the above steps, grinding for 3-4 hours under the effect of emulsification pump.

Description

1. Technical field: [0001] The invention relates to a method for preparing fertilizer, in particular to a method for preparing water-soluble fertilizer containing humic acid. 2. Background technology: [0002] At present, in order to reduce the cost of many humic acid liquid fertilizers in China, the humic acid is mostly sodium humate, which will pollute the environment in the remaining residue after extraction. [0003] In addition, many humic acid fertilizers are mainly based on humic acid and macroelements, ignoring the addition of several trace elements. At present, farmers pay more attention to the use of macronutrient fertilizers. Trace elements are ignored because of their small amount, but the role of trace elements cannot be replaced by macronutrients, thus affecting the final yield of crops. [0004] Some trace elements are directly added to humic acid, but potassium humate or sodium humate will react with acidic trace element raw materials to form flocculation, a...
