Embodiment 1

[0015] Example 1 Potassium-containing shale was selected, and the potassium oxide content was detected to be 8.1%. 160 kg was taken and crushed to 300 mesh, and 40 kg of grass carbon (humic acid) was crushed to 250 mesh. The two were mixed and stirred evenly. Add 2.5 kg of Bacillus megarius debary dry bacteria, 3 kg of jelly-like Bacillus mucilaginosus dry bacteria and 2.5 kg of enzyme bacteria, and add an appropriate amount of warm water to stir. The bacterial content of the above two dried bacteria is 5-10 billion strains / gram. Adjust the pH value to 6.5-7, keep the ambient temperature at 28-33°C, and keep the humidity above 60%, ferment for 12 days, then add 5 kg each of urea and potassium sulfate and stir evenly. Obtain 250 kilograms of biomineral compound fertilizers. Among them, the active ingredient content is 15% of organic matter; 10.1% of potassium oxide; 2.03% of zinc, iron, copper and other trace elements in total; 2.11% of calcium, magnesium, sulfur and other me...

Embodiment 2

[0016] Example 2 Potassium-containing shale was selected, the potassium oxide content was detected to be 8.3%, 320 tons were taken and crushed to 250 mesh, 80 tons of humic acid were crushed to 200 mesh, and the two were mixed and stirred evenly. Add 8 tons of Bacillus megarius debary dried bacteria, with a bacterial content of 8 billion strains / gram. 10 tons of jelly-like Bacillus mucilaginosus dried bacteria and 4 tons of enzyme bacteria, the bacteria content is 10 billion strains / gram. And add an appropriate amount of warm water and stir. Adjust the pH value to 6.5-7, keep the ambient temperature at 28-33°C, and keep the humidity at 70%, ferment for 15 days, then add 5 tons of urea and 7 tons of potassium sulfate and stir evenly. Obtain 500 tons of biomineral compound fertilizer. Among them, the weight percentage of active ingredients is 18% of organic matter; 9.8% of potassium oxide; 2.44% of zinc, iron, copper and other trace elements in total; 1.63% of calcium, magnesi...

Embodiment 3

[0017] Example 3 Select 70 tons of potassium-containing shale, detect 8% potassium oxide content, and crush to 250 mesh, 30 tons of humic acid are crushed to 200 mesh, and the two are mixed and stirred evenly. Add 2.5 tons of dried bacteria of Bacillus megarius debary, with a bacterial content of 8 billion strains / gram. 3 tons of Bacillus subtilis dry bacteria and 2 tons of enzyme bacteria, the bacteria content is 10 billion strains / gram. And add an appropriate amount of warm water and stir. Adjust the pH value to 6.5-7, keep the ambient temperature at 28-33°C, and keep the humidity at 75%, ferment for 13 days, then add 3 tons of urea and 3.5 tons of potassium sulfate and stir evenly. Obtain 150 tons of biomineral compound fertilizer. The weight percent content of active ingredients detected is organic matter 20.8%; potassium oxide 5.9%; zinc, iron, copper and other trace elements total 2.84%; calcium, magnesium, sulfur and other medium elements total 1.70%; urea 2.0%; Bact...

Abstract

The invention relates to a biomineral compound fertilizer, which comprises the following effective ingredients: 15 to 20 weight percent of organic substances, 5.8 to 10.3 weight percent of potassium oxide, 2 to 2.95 weight percent of microelements such as iron and copper, 1.5 to 2 weight percent of medium elements such as calcium, magnesium and sulfur, 1 to 5 weight percent of urea, 3 to 5 weightpercent of phosphorus and potassium decomposing bacteria, and the balance being water and impurities, wherein the pH value of the fertilizer is between 6.5 and 7. The biomineral compound fertilizer contains the effective ingredients required by various crops, and has most nutritive compositions required for crop growth. The phosphorus and potassium decomposing bacteria in the biomineral compound fertilizer can also decompose insoluble phosphorus and potassium elements in soil, and are favorable for crop absorption. Moreover, the biomineral compound fertilizer promotes material exchange and beneficial cycle of a cropland biosphere 'soil-plant-animal-microorganism'.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a compound fertilizer containing microorganisms for planting fine crops. Background technique [0002] Fertilizer is the grain of crops, and the three elements of nitrogen, phosphorus, and potassium are indispensable nutrients for the growth and development of all plants. For this reason, people invented chemical fertilizers, but the long-term and large-scale use of chemical fertilizers, especially the excessive use of nitrogen fertilizers, has led to a series of worldwide problems such as land compaction, soil and water pollution, and crop quality decline. For this reason, many restrictions have been imposed on the use of chemical fertilizers in agriculture internationally. Some countries even ban the use of chemical fertilizers. The damage of chemical fertilizers to the environment is mainly due to the residues of various salts, acid radicals and heavy metals during the decomposi...
