Problems solved by technology

For most crops, acidic soil will inhibit growth and cause quality deterioration, which will cause great harm to the ecological environment and human survival
[0004] Soil acidification is largely caused by long-term unreasonable fertilization and farming management. Most of the fertilizers sold on the market are inorganic fertilizers that mainly provide nitrogen, phosphorus and potassium, and most of them are chemical acidic or physiological acidic fertilizers. Long-term application Aggravate soil acidification

Embodiment 1

[0029] 500 parts of urea, 230 parts of calcium magnesium phosphate fertilizer, 185 parts of potassium chloride, 60 parts of potassium humate, 25 parts of filler.

[0030] Step 1: Melt 500 parts of urea at high temperature (130°C-140°C), enter the buffer tank, pressurize it through the delivery pump, and send it to the mixing tank at the top of the tower after metering.

[0031] Step 2: Measure 230 parts of calcium magnesium phosphate fertilizer, 185 parts of potassium chloride, 60 parts of potassium humate, and 25 parts of filling material respectively, and send them into the mixer for thorough mixing. The mixed raw materials are sent to the mixing heater after being crushed and screened, heated to 70°C-80°C, and then lifted to the tower top silo by the bucket elevator.

[0032] Step 3: the heated mixed material in the tower top silo in step 2 is evenly measured by a screw weighing scale and sent into the mixing tank described in the above step 1, mixed by a high-speed shear m...

Embodiment 2

[0035] 500 parts of urea, 280 parts of calcium magnesium phosphate fertilizer, 170 parts of potassium chloride, 40 parts of potassium humate, and 10 parts of filler.

[0036] The specific implementation steps are the same as the implementation example 1.

[0037] The resulting product specification is 23-5-11

Embodiment 3

[0039] 500 parts of urea, 330 parts of calcium magnesium phosphate fertilizer, 160 parts of potassium chloride, 10 parts of potassium humate

[0040] The specific implementation steps are the same as the implementation example 1.

[0041] The resulting product specification is 23-6-10

Abstract

The invention discloses tower-type melt granulation fertilizer special for improvement of acid soil and a preparation method thereof, belonging to the technical field of agricultural fertilizer. The fertilizer is prepared from urea, calcium magnesium phosphate, potassium chloride, potassium humate and filler. According to the tower-type melt granulation fertilizer special for improvement of acid soil, provided by the invention, aiming at the defects of the prior art, on the basis of a tower-type melt granulation compound fertilizer facility, the fertilizer is scientifically and reasonably prepared by combining the actual condition of the acid soil, and has the advantages of being balanced in nutritive substances, stable, smooth in appearance, and not easy to harden; the acid soil can be improved, and the soil acidity can be reduced; the formula is reasonable, the nutrition is comprehensive. The fertilizer can be used for comprehensively improving the acid soil, and improving the soil quality to increase the yield of crops.

Description

technical field [0001] The invention belongs to the technical field of functional fertilizers, and relates to a tower-type melt granulation special fertilizer for acidic soil improvement and a preparation method thereof. Background technique [0002] The agricultural production activities of human beings are mainly carried out on the soil. The agricultural products needed by human beings are produced directly or indirectly from the soil. The properties of the soil restrict the growth and development of plants and the effect of agricultural production measures to a large extent. The foundation is an indispensable natural resource for human beings. [0003] Soil acidification is the process of increasing hydrogen ions in the soil or the process of soil acidity changing from low to high. At present, the national soil pH value has dropped by an average of 0.6 units in the past 30 years, and the acidification of the soil is still intensifying. Soil acidification in my country m...
