Embodiment 1
[0042] This embodiment is an amino acid long-acting formula fertilizer, comprising the following components in parts by weight:
[0043] 100 parts of urea, 90 parts of monoammonium phosphate, 80 parts of potassium chloride, 30 parts of amino acid solution, 10 parts of long-acting mixture;
[0044] The amino acid solution is prepared by dissolving 30 parts by weight of glutamic acid, 40 parts by weight of reducing sugar, and 30 parts by weight of soluble protein in 80 parts by weight of water; the long-acting mixture ammonium polyphosphate, polyacrylic acid A mixture of sodium, dicyandiamide and potassium humate in a weight ratio of 15:1:20:8.
Embodiment 2
[0046] This embodiment is an amino acid long-acting formula fertilizer, comprising the following components in parts by weight:
[0047] 150 parts of urea, 130 parts of monoammonium phosphate, 120 parts of potassium chloride, 50 parts of amino acid solution, 20 parts of long-acting mixture;
[0048] The amino acid solution is prepared by dissolving 30 parts by weight of glutamic acid, 40 parts by weight of reducing sugar, and 30 parts by weight of soluble protein in 100 parts by weight of water; the long-acting mixture ammonium polyphosphate, polyacrylic acid A mixture of sodium, dicyandiamide and potassium humate in a weight ratio of 15:1:20:8.
Embodiment 3
[0050] see Figure 1-7 As shown, the present embodiment is a preparation method of amino acid long-acting formula fertilizer, comprising the following steps:
[0051] Step 1: Weigh the raw materials by weight, mix urea, monoammonium phosphate, potassium chloride, and long-acting mixture, and then put them into a pulverizer to pulverize to obtain powder mixed fertilizer. Spray the amino acid solution on the powder mixed fertilizer and mix evenly , and then adding the spray powder mixed fertilizer of the amino acid solution to the granulator to make mixed fertilizer granules;
[0052] Step 2: Open the sealing cover 112 of the fertilizer drying and screening equipment, pull out the sealing plug 114, add the mixed fertilizer particles into the inner cavity of the drying bin 113, install the sealing plug 114 and the sealing cover 112, start the heating net 119 to release The heat heats the drying bin 113, and then the mixed fertilizer particles are heated:
[0053] Step 3: start ...
