Embodiment 1

[0072] A preparation method of soil improvement type biological fertilizer, the steps are as follows:

[0073](1) Bacillus subtilis (Bacillus subtilis) ACCC03120, jelly-like Bacillus (Bacillus mucilaginosus) CICC23640 and Bacillus megaterium (Bacillus megaterium) CICC21694 were inoculated in liquid seed medium respectively, and cultured in liquid at 30°C for 24 hours, and then Inoculate in a liquid fermentation medium with an inoculation amount of 10wt%, culture at 30°C for 3 days, then add 1.5g of peat to each milliliter of liquid fermentation medium, absorb for 30min, dry at 45°C, pulverize, and sieve;

[0074] 8×10 live bacteria containing Bacillus subtilis ACCC03120 were prepared respectively 9 Bacteria agent A, jelly-like bacillus CICC23640 viable count 6×10 per g 9 Bacteria agent B containing Bacillus megaterium CICC21694 count 5×10 per g 9 Individual / g of bacterial agent C;

[0075] The liquid seed medium in the step (1) is prepared by mixing and sterilizing the foll...

Embodiment 2

[0098] The preparation method as described in Example 1, the difference is that in step (5), the prepared bacterial agent A, bacterial agent B, bacterial agent C, bacterial agent D, bacterial agent E and bacterial agent F are weighed by weight Mixed at a ratio of 1:2:2:3:1:1 to prepare a composite microbial agent with a total bacterial count of 4.3×10 9 pcs / g.

Embodiment 3

[0100] Peat 200kg, organic fertilizer 200kg, inorganic fertilizer 400kg, porous inorganic matter 80kg, clay 80kg, trace element 20kg are mixed with the compound microbial inoculum agent 20kg that makes in the embodiment 2, and the composite mixture that mixes is transported to The compound microbial fertilizer can be obtained by granulating in a granulator and drying at low temperature.

[0101] The organic matter content of the obtained fertilizer is 20wt%, the total content of N, P and K is 20wt%, and the number of effective viable bacteria is 80 million / g.

Abstract

The invention relates to a soil-improving bio-fertilizer and a preparation method thereof. The soil-improving bio-fertilizer is prepared by mixing the following raw materials in parts by weight: 200-400 parts of grass carbon, 200-400 parts of an organic fertilizer, 100-400 parts of an inorganic fertilizer, 50-200 parts of a porous inorganic matter, 10-30 parts of trace elements, 50-80 parts of clay and 10-20 parts of a compound microbial agent. A plurality of microorganisms with the functions of fixing nitrogen, solubilizing phosphate and solubilizing potassium are added into the fertilizer, so that the nitrogen content of soil can be increased, the utilization ratio of a chemical fertilizer is increased, the soil structure is improved, the crop yield is increased, and the crop quality is enhanced.

Description

technical field [0001] The invention relates to a soil-improving biological fertilizer and a preparation method thereof, belonging to the technical field of biological fertilizers. technical background [0002] With the development of my country's agriculture, the application of chemical fertilizers has become the main measure to increase agricultural production. The long-term use of chemical fertilizers such as nitrogen and phosphorus will destroy the soil structure, resulting in soil compaction, soil degradation of cultivated land, shallowing of the cultivated layer, and decline in water and fertilizer retention. The yield and quality of crops have been seriously affected; the extensive use of pesticides has caused the accumulation of pesticides in plants, which endangers the health of humans and livestock through food and feed. Therefore, effective and rational use of chemical fertilizers, reduction of pesticide application, reduction of environmental pollution, and elimin...
