Example Embodiment
[0036] Example 1:
[0037] Raw material ratio: 378 parts of ammonium nitrate phosphorus, 200 parts of potassium nitrate, 135 parts of potassium dihydrogen phosphate, 270 parts of potassium sulfate, 5.9 parts of boric acid, 3.9 parts of EDTA chelated iron, EDTA chelated zinc 3.3 parts, EDTA chelated manganese 3.9 parts Copies.
[0038] step 1 : Melt 378 parts of ammonium nitrate at high temperature (150℃~165℃), enter the buffer tank, pressurize by the transfer pump, and send it to the mixing tank at the top of the tower after being measured.
[0039] Step 2: First, 5.9 parts of boric acid, 3.3 parts of EDTA chelated zinc, 3.9 parts of EDTA chelated iron, and 3.9 parts of EDTA chelated manganese are pre-mixed in a certain proportion, and then the mixture is mixed with 135 parts of potassium dihydrogen phosphate and 200 parts of potassium nitrate , 270 parts of potassium sulphate are weighed separately and then sent to the agitator for full mixing. The mixed raw materials are crushe...

[0042] Example 2:
[0043] Raw material ratio: 375 parts of ammonium nitrate phosphorus, 200 parts of potassium nitrate, 135 parts of potassium dihydrogen phosphate, 270 parts of potassium sulfate, 5.9 parts of boric acid, 3.9 parts of EDTA chelated iron, EDTA chelated zinc 3.3 parts, EDTA chelated manganese 3.9 parts Servings, 3 servings of seaweed extract.
[0044] The specific implementation steps are the same as in Example 1.
[0045] The product specification obtained is 15-8-28+3‰ seaweed extract + TE (boron 0.1%, iron 0.05%, zinc 0.05%, manganese 0.05%)
