preparation example Construction

[0025] The method for preparing the above-mentioned organic-inorganic three-nitrogen green environmental protection compound fertilizer includes the following steps:

[0026] (1) In the production of compound fertilizer by granular method, 14%-22% of the total input raw materials are added into the melting tank to make a slurry with a temperature of 100-110°C for use;

[0027] (2) The metered humic acid, urea, monoammonium phosphate and potassium chloride are added to the drum granulator through the microcomputer batching system, and the ammonium nitrate phosphorus slurry prepared in step (1) is in the drum granulator Complete the granulation process. In the granulation process, the ammonium nitrate phosphorus slurry is used as the amount of liquid phase required for granulation, the heat is used to heat the material, and the viscosity of the urea nitrate generated by the reaction with urea is used to complete the material granulation process; Too much urea nitrate is produced duri...

Embodiment 1

[0035] To prepare a product with 15% organic matter content and 20-13-5 nitrogen, phosphorus, and potassium content, take the raw material consumption quota of 1 ton as an example:

[0036]

[0037] Specific production process: ammonium nitrate phosphorus (containing 30% N, 14.5% nitrate nitrogen, 15.5% ammonium nitrogen, P 2 O 5 6%, mass percentage, the same below) 170 kg is metered and added to the melting device to make a slurry with a temperature of 100℃. At the same time, 170 kg of urea (containing N46.2%) and powdered monoammonium phosphate are metered by a computer. (Containing N11%, P2O545%) 270 kg, potassium chloride (containing K 2 O60%) 85 kg, humic acid (containing 61% organic matter) 255 kg, the above materials and the pressurized atomized ammonium nitrate phosphorus slurry are mixed in the drum granulator, and gas ammonia (containing N82. %) 50 kg, after being measured, pass into the drum granulator material layer, after 5min granulation, enter the dryer, the inlet a...

Embodiment 2

[0039] To prepare a product with an organic content of 16% and a nitrogen, phosphorus, and potassium content of 16-10-12, take the raw material consumption quota of 1 ton as an example:

[0040]

[0041]

[0042] Nitrate ammonium phosphorus (containing 30% N, which contains 14.5% nitrate nitrogen, 15.5% ammonium nitrogen, P 2 O 5 6%, mass percentage, the same below) 150 kg is metered and added to the melting device to make a slurry with a temperature of 105°C. At the same time, 150 kg of urea (containing N46.2%) and powdered monoammonium phosphate are metered by a computer (Containing N11%, P2O545%) 205 kg, potassium chloride (containing K 2 O60%) 200 kg, humic acid (containing 61% organic matter) 265 kg, the above materials and the pressurized atomized ammonium nitrate phosphorus slurry are mixed in the drum granulator, and gas ammonia (containing N82. %) 30 kg, after being measured, pass into the drum granulator material layer, after 7 minutes of granulation, enter the dryer, th...

Abstract

The invention discloses a green environment-friendly compound fertilizer prepared from three kinds of organic-inorganic nitrogen and a preparation method thereof. By mass percent, humic acid is 25% to 30% of the total amount of raw materials, liquid ammonia is 3% to 5% of the total amount of the raw materials, nitramine phosphorus is 14% to 22% of the total amount of the raw materials, urea is 14% to 22% of the total amount of the raw materials, monoammonium phosphate is 20% to 30% of the total amount of the raw materials, and potassium chloride is 8.5% to 20% of the total amount of the raw materials. The raw materials which contain organic matter, nitrate nitrogen, ammonium nitrogen, amide nitrogen and other phosphorus and potassium elements are added to ingredients. By using the fertilizer, the utilization rate of fertilizer nutrients can be improved, so that the crop yield is increased, the quality is improved, and the harm caused by toxic substances of heavy metals such as cadmium, lead, arsenic, chromium and the like, living grasshopper egg and escherichia coli can be avoided. Additionally, the soil is improved, the soil salinity is reduced, a product contains 2% to 3% of nitrate nitrogen, and the mass ratio of the amide nitrogen to the ammonium nitrogen is 1: (1 to 1.4).

Description

Technical field [0001] The invention relates to an organic-inorganic compound fertilizer, in particular to an organic-inorganic three-nitrogen green environment-friendly compound fertilizer and a preparation method thereof. The final product contains organic matter and three kinds of nitrogen: nitrate nitrogen, ammonium nitrogen and amide State nitrogen. Background technique [0002] Global agricultural production is developing in the direction of organic agriculture and green agriculture. This is the development trend of world agriculture and the way out for sustainable agricultural development in China. The development of agriculture is inseparable from the use of chemical fertilizers. At present, the use of fertilizers in our country is in the period of scientific fertilization with crop yield, product quality and ecological environment as the three-dimensional goal, to improve crop quality, improve soil structure, organic planting, and green agricultural production. Is the c...
