Embodiment 1

[0017] Weigh raw materials according to the following ratio (kg)

[0018] Potassium sulfate 160, urea 260, monoammonium phosphate 160, bentonite 120, humic acid 80, microbial agent 0.02, calcium powder 220.

[0019] Azotobacter, Bacillus megaterium, Bacillus cereus, Bacillus subtilis and potassium-solubilizing strains were used as the original strains, which were respectively activated on the slope of conventional strains, cultured at constant temperature on a liquid shaker in a triangular flask, and cultured in a culture tank, and then the culture of the above strains The mixed granulation of the microbial agent cultured by fermentation and potassium sulfate, urea, monoammonium phosphate, bentonite, humic acid and calcium powder organic and inorganic fertilizers in equal amounts is sprayed and coated by drum spraying, and dried by low-temperature wind. The bio-organic-inorganic compound fertilizer of the present invention is made by sieving.

Embodiment 2

[0021] According to embodiment 1, take by weighing raw material (kg) according to following proportioning

[0022] Potassium sulfate 200, urea 220, monoammonium phosphate 200, bentonite 80, humic acid 120, microbial agent 0.05, calcium powder 180.

Embodiment 3

[0024] According to embodiment 1, take by weighing raw material (kg) according to following proportioning

[0025] Potassium sulfate 180, urea 240, monoammonium phosphate 180, bentonite 100, humic acid 100, microbial agent 0.03, calcium powder 200.

Abstract

The invention discloses a biological organic and inorganic compound fertilizer which is particles prepared from potassium sulfate, urea, monoammonium phosphate, bentonite, humic acid, a microbial agent and a calcium powder as raw materials; the compound fertilizer contains beneficial active bacteria, can be decomposed into elemental phosphorus and potassium convenient for crops to use, and can accelerate the crop absorption on phosphorus and potassium, and has the functions of self fixing nitrogen, balancing and adjusting various nutrient elements required for the crops, lasting fertilizer efficiency, increasing soil organic matters, preventing soil hardening, and effectively improving a soil ecological structure.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer production, and in particular relates to a bio-organic-inorganic compound fertilizer. Background technique [0002] At present, the fertilizers used in farmland are mainly inorganic chemical fertilizers and organic fertilizers. Inorganic chemical fertilizers have been used on a large scale in my country since the 1960s and 1970s. The amount and area of ​​fertilizer application increased rapidly. played a significant role. However, in the 1970s, my country's cultivated land was generally deficient in nitrogen, in the 1980s, in the 1980s, in the 1990s, and in the 1990s, there was a lack of potassium. After entering 2000, there was an excess of nitrogen and phosphorus in soil fertility, potassium and beneficial microorganisms and The lack of organic matter has turned many farmlands into "hygienic fields" without organic matter. The reduction of organic matter content also leads to the red...
