Problems solved by technology

[0007] 1. Most of them are ordinary inorganic fertilizers. Long-term use will make the soil harden, weaken the soil fertility, and seriously damage the aggregate structure of the soil;
[0008] 2. Uneven fertilizer nutrients;
[0009] 3. The fertilizer effect is short and the utilization rate is low, which is easy to cause nutrient loss and later defert

Embodiment 1

[0047] Components: 360 parts of urea, 480 parts of potassium sulfate, and 160 parts of monoammonium phosphate.

[0048] Preparation method: 1) Melt 360 parts of urea at high temperature (130°C-140°C), put it into the buffer tank, pressurize it with a delivery pump, and pump it into the top mixer.

[0049] 2) Put 480 parts of potassium sulfate and 160 parts of monoammonium phosphate into the mixer after metering and mix well. After the mixed raw materials are crushed and screened, they are sent to the mixing heater to be heated to 85-90°C. Send it to the silo at the top of the tower with a bucket elevator.

[0050]3) The hot mixture in the tower top silo in step 2) is evenly measured by a spiral meter and then sent to the mixer mentioned in the above step 1), mixed by a high-speed shear mixer to make a thin paste material, and the temperature is controlled At 100°C-120°C, the particle impurities are filtered out by the vibrating filter and then overflow to the granulation noz...

Embodiment 2

[0053] Components: 394.3 parts of urea, 100 parts of potassium dihydrogen phosphate, 50 parts of monoammonium phosphate, 410 parts of potassium sulfate, 6 parts of boric acid, 4 parts of EDTA chelated iron, 3.3 parts of EDTA chelated zinc, 4 parts of EDTA chelated manganese, 0.4 parts of ammonium heptamolybdate, 10 parts of anhydrous magnesium sulfate, 8 parts of inhibitor NAM, and 10 parts of potassium fulvic acid.

[0054] Preparation method: with implementation example 1.

[0055] The resulting product has a specification of 18-8-25 and contains potassium fulvate, inhibitors and medium and trace elements.

Embodiment 3

[0057] Components: 344.3 parts of urea, 160 parts of monoammonium phosphate, 110 parts of potassium dihydrogen phosphate, 500 parts of potassium sulfate, 6 parts of boric acid, 4 parts of EDTA chelated iron, 3.3 parts of EDTA chelated zinc, 4 parts of EDTA chelated manganese, 0.4 parts of ammonium heptamolybdate, 10 parts of anhydrous magnesium sulfate, 8 parts of inhibitor NAM, and 10 parts of potassium fulvic acid.

[0058] Preparation method: with implementation example 1.

[0059] The resulting product has a specification of 15-6-30 and contains potassium fulvate, inhibitors and medium and trace elements.

Abstract

The invention discloses a fulvic acid potassium-containing total-nutrient fertilizer for special purpose of potatoes and a production method thereof, and belongs to the technical field of crop formula special fertilizers. The fertilizer is prepared from the following raw materials: urea, monoammonium phosphate, monopotassium phosphate, potassium sulfate, boric acid, EDTA chelated zinc, EDTA chelated iron, EDTA chelated manganese, ammonium heptamolybdate, anhydrous magnesium sulfate, inhibitor NAM and fulvic acid potassium. The fertilizer has the advantages of balanced and comprehensive nutrition, smooth appearance, hardening prevention, long fertilizer efficiency, high utilization, labor output reduction, soil improvement and environmental pollution reduction.

Description

technical field [0001] The invention belongs to the technical field of fertilizer specially formulated for crops, and in particular relates to a special fertilizer for full nutrition potatoes containing potassium fulvic acid and a preparation method thereof. Background technique [0002] Potato, also known as potato, belongs to Solanaceae Solanum, an annual herb. Native to the Andes Mountains in South America, it has been widely planted all over the world. It is highly valued by the world because of its high and stable yield, wide adaptability, complete nutritional content and long industrial chain. It is known as the "second bread" of human beings. , is the fourth largest food crop after wheat, rice and corn in the world. However, compared with pure food crops such as rice and wheat, potatoes have lower requirements on climatic conditions, strong geographical adaptability, less water consumption, easy planting, long industrial chain, and great room for processing and addin...
