Problems solved by technology
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.
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 macroelements, thus affecting the final yield of crops.
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, and then form precipitation, humic acid and trace elements become invalid , causing great waste; in addition, the sediment will also block the nozzle of the sprayer, which is not conducive to farmers' use

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 addingCa, 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
A kind of preparation method of water-soluble fertilizer containing humic acid 1. Technical field: 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: 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. 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. Some trace elements are directly added to humic acid, but potassium humate or sodium humate will react with acidic tr...
