preparation Embodiment 1
[0020] Preparation Example 1: First, according to β-aminobutyric acid (BABA) 5%, potassium nitrate 24.7%, monoammonium phosphate 11.9%, potassium dihydrogen phosphate 23.6%, urea 31.2%, boric acid 0.4%, EDTA-Fe 1.9%, Prepare materials with EDTA-Mn 0.6% and EDTA-Zn0.7%, check that the purity of each raw material is not less than 99.0%, and the raw material moisture is controlled below 3%; then urea is crushed to a particle size of 0.4mm; finally all the raw materials are over 40 After mesh sieving, mix evenly to obtain finished fertilizer.
preparation Embodiment 2
[0021] Preparation Example 2: First, according to β-aminobutyric acid 6%, potassium nitrate 16.0%, monoammonium phosphate 1.0%, potassium dihydrogen phosphate 37.0%, urea 37.0%, boric acid 1.0%, EDTA-Fe 1.0%, EDTA-Zn Prepare materials at 1.0%, check that the purity of each raw material is ≥99.0%, and the moisture content of the raw material is controlled below 3%; then urea is crushed to a particle size of 0.4mm; finally, all the raw materials are passed through a 40-mesh sieve and mixed uniformly to obtain the finished fertilizer.
preparation Embodiment 3
[0022] Preparation Example 3: First, according to β-aminobutyric acid 4%, potassium nitrate 14.5%, monoammonium phosphate 1.0%, potassium dihydrogen phosphate 38.0%, urea 38.0%, boric acid 0.6%, EDTA-Fe 1.9%, EDTA-Mn 0.6%, EDTA-Zn 0.7%, EDTA-Cu 0.69%, and sodium molybdate 0.01% are prepared. Check that the purity of the raw materials is ≥99.0%, and the moisture content of the raw materials is controlled below 3%; then the urea is crushed to a particle size of 0.4mm; finally all the raw materials are passed through a 40-mesh sieve and mixed uniformly to obtain the finished fertilizer.
