Embodiment 1

[0037] To produce humic acid vegetable base fertilizer with 30% total nutrients, the specific method is as follows:

[0038] 1. Processing of weathered coal powder rich in humic acid

[0039] The weathered coal rich in humic acid stripped from the coal mine is transported from the mining field to the storage yard, dried to reduce the moisture to 23-27%, and then sent to a high-pressure suspension roller mill to grind 90% of which can pass through 80 mesh Sift the fine powder.

[0040] 2. Other raw materials crushed

[0041] The granular raw materials of urea, ammonium bicarbonate, monoammonium phosphate, potassium chloride, potassium sulfate and other raw materials are respectively pulverized to below 40 mesh with a cage crusher.

[0042] 3. Produce 1 ton of humic acid vegetable base fertilizer

[0043] Weathered coal powder (humic acid weight content 43.4%, moisture weight content 25%, 90% through 80 mesh sieve) 381.5kg and ammonium bicarbonate (N weight content 17.1%, 40 ...

Embodiment 2

[0046] 1) Grinding weathered coal with humic acid dry basis weight content of 60% and moisture weight content of 27% with a pulverizer into weathered coal powder of which 90% can pass through a fineness of 80 mesh sieves;

[0047] 2) Stir and mix 30 kg of weathered pulverized coal with 10 kg of agricultural ammonium bicarbonate that can pass through a 40-mesh sieve through a pulverizer, and the stirring time can usually be 10 minutes;

[0048] 3) According to the design formula of nutrients required by crops, 5kg of urea, 7kg of ammonium sulfate, 8kg of diammonium phosphate, 15kg of potassium nitrate and medium and trace element compounds such as calcium carbonate, magnesium oxide, sulfur powder, sodium silicate, A total of 2 kg of manganese sulfate, siderite powder, smithsonite powder, borax, copper oxide and sodium molybdate are added to the material in step 2) and continue to stir and mix, and the stirring time is usually 4 minutes;

[0049] 4) The evenly mixed ammonium hum...

Embodiment 3

[0051] 1) Grinding weathered coal with humic acid dry basis weight content of 55% and moisture weight content of 23% with a pulverizer into weathered coal powder wherein 90% can pass through 80 mesh sieve fineness;

[0052] 2) Stir and mix 70 kg of weathered coal powder and 25 kg of agricultural ammonium bicarbonate that can pass through a 40-mesh sieve through a pulverizer, and the stirring time can usually be 12 minutes;

[0053] 3) According to the design formula of nutrients required by crops, urea 21kg, ammonium nitrate 28kg, monoammonium phosphate 22kg, potassium sulfate 40kg and medium and trace element compounds calcium carbonate, magnesium oxide, sulfur powder, sodium silicate, , manganese sulfate, siderite powder, smithsonite powder, borax, copper oxide and sodium molybdate add a total of 8kg into step 2) and continue stirring and mixing in the material, and the stirring time is usually 5 minutes;

[0054] 4) The evenly mixed ammonium humate compound fertilizer is pa...

Abstract

The invention relates to a humic acid fertilizer, which in detail relates to a process for preparing humic acid ammonium compound fertilizer. The process comprises following steps: (1) grinding weathered coal in which the weight proportion of humic acid dry material is 50-75% and weight proportion of water is 20-30%, with roller mill into weathered coal powder, and 90% of the weathered coal powder can come across the screen of 80 fineness; (2) mixing the weathered coal powder with ammonium bicarbonate for agricultural use according to ratio of 30-70: 6-18, and said ammonium bicarbonate is disintegrated with mill so that it can cross screen of 40 fineness; (3) adding nitrogen, phosphorus, potassium and/ or medium-micro element that can cross the screen of 40 fineness into material in step (2); (4) packing mixed humic acid ammonium compound fertilizer, and storing for 3-7 days, then leaving factory. The invention is characterized by short process and saved energy.

Description

technical field [0001] The invention relates to a humic acid fertilizer, in particular to a processing method of a humic acid ammonium compound fertilizer. Background technique [0002] Humic acid fertilizer, because it can increase crop yield, improve the quality of agricultural products, improve soil, improve nutrient utilization rate, enhance crop resistance to disease, drought resistance, frost resistance, salt and alkali resistance, etc. compared with chemical fertilizers and compound fertilizers (compound fertilizers) ) has great advantages, and has gradually been recognized and accepted by farmers, and has become an important variety in the fertilizer family. [0003] For the processing of humic acid compound fertilizers, some enterprises dry and pulverize raw materials rich in humic acid, such as weathered coal and peat soil, etc., and mix them with raw materials containing nitrogen, phosphorus, potassium and compounds containing medium and trace elements to form the...
