Example Embodiment

[0025] Reference figure 1 , Is the flow chart of the preparation method of organic-inorganic compound fertilizer of the present invention. The method includes:

[0026] Step 101, mixing the urea solution or ammonium nitrate solution with potash fertilizer to obtain a mixture;

[0027] Wherein, the potash fertilizer is potassium chloride, and the mixing also includes a filler. The filler may be one or more of ammonium sulfate, ammonium chloride, and dolomite powder.

[0028] Step 102, mixing and chelating potassium fulvic acid or ammonium humate with monoammonium phosphate and the mixture.

[0029] The potash fertilizer and filler are directly mixed with the urea solution heated to 130°C to 170°C or the ammonium nitrate solution heated to 130°C to 170°C at 130°C to 170°C. Then it is mixed and chelated with monoammonium phosphate, potassium fulvic acid or ammonium humate.

[0030] The method of the present invention uses potassium fulvic acid or ammonium humate as organic matter, which...

Example Embodiment

[0037] Example 1:

[0038] Compound fertilizer product specifications: according to mass percentage, N:P 2 O5: K 2 O=30:5:5, total nutrients ≥40%, organic matter ≥10%, moisture ≤2.0%. Nutrients refer to nitrogen, phosphorus, and potassium, and organic matter refers to potassium fulvic acid or ammonium humate.

[0039] Urea, monoammonium phosphate, potassium chloride, potassium fulvic acid, and filler are lifted into the silo at the top of the high tower by elevators, and urea is metered into the melting tank, heated to 130℃~170℃, and then passed through overflow The flow is mixed and chelated with the metered monoammonium phosphate, potassium chloride, potassium fulvic acid, and fillers in the mixing tank, and then enters the granulator for spray granulation after uniformity. After cooling and screening, the qualified The particles are surface-treated and then packaged and shipped.

Abstract

The invention discloses a tower-smelt organic-inorganic compound fertilizer and a preparation method thereof. The invention relates to the agriculture technical field, and specifically relates to an organic-inorganic compound fertilizer and a preparation method thereof. The method comprises the following steps: A, mixing carbamide solution or ammonium nitrate solution with potash fertilizer to obtain the mixture; and B, mixing and chelating potassium fulvate or ammonium humate with the mixture. In the organic-inorganic compound fertilizer prepared by the method, the weight percentage of the total content of nitrogen, phosphorus and potassium is more than or equal to 20%, the weight percentage of the content of the potassium fulvate or the humate is more than or equal to 8%, and the weightpercentage of the content of moisture is less than or equal to 2.0%. The organic-inorganic compound fertilizer has quick action of the chemical fertilizer, and also has the long residual action, soilimprovement effect and multifunctional environmental protection of the organic fertilizer, achieving the multiple effects of developing agriculture, improving soil and the like.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an organic-inorganic compound fertilizer and a preparation method thereof. Background technique [0002] In order to promote the rapid and high-quality growth of crops in agricultural production, fertilizers play an important role in agricultural development. [0003] The use of a large amount of chemical fertilizers has caused serious land compaction, widespread crop diseases and insect pests, a decline in the utilization rate of chemical fertilizers, and serious agricultural non-point source pollution. At present, the combination of chemical fertilizers and organic fertilizers to produce organic-inorganic compound fertilizers has become a hot spot in the production of chemical fertilizers. [0004] The existing method for preparing organic-inorganic compound fertilizers is to use steam humidification method to agglomerate or spray granulate, and to dope organic matter in...
