Example Embodiment
[0020] A preparation method of humic acid-containing water-soluble fertilizer with enhanced crop resistance, including the following steps:
[0021] Step 1: Place urea, ammonium sulfate, potassium nitrate, potassium tripolyphosphate and polyglutamic acid in a grinder to grind and grind to 80-200 mesh;
[0022] Step 2: Place the mixture ground to 80-200 mesh in Step 1 in the blender;
[0023] Step 3: Add humic acid, EDTA chelated zinc, amino acid chelated boron and EDTA chelated manganese to the blender where the mixture is put in step two and stir for 30 minutes. After the above materials are evenly mixed, pass through the elevator Lift the material into the silo;
[0024] Step 4: Allow the material in the silo in step 3 to stand for 10 minutes and then be filled to form a humic acid-containing water-soluble fertilizer; the pH value of the humic acid-containing water-soluble fertilizer is 7.5-9.
[0025] In order to explain the present invention more clearly, it will now be further des...
