[0053] In order to further improve the performance of the present invention, embodiment two of the present invention provides another kind of nano-microbe organic-inorganic compound fertilizer, comprising:

[0054] By weight, 0.15-0.2 parts of Bacillus megaterium, 0.15-0.2 parts of jelly-like Bacillus, 0.15-0.2 parts of Bacillus subtilis, 50-90 parts of phosphogypsum, 50-90 parts of superphosphate, and 50- parts of fly ash 90 parts, montmorillonite 5-40 parts, humic acid 80-200 parts, layered silicate 5-40 parts.

[0055] The above-mentioned components can be used in any number of parts within the range of the number of parts.

[0056] The preparation method of above-mentioned nano-microbe organic-inorganic compound fertilizer, such as figure 2 shown, including the following steps:

[0057] Step 201: respectively culturing the strains of Bacillus megaterium, Bacillus subtilis, and Bacillus jelly-like to obtain the strains in the spore state;

[0058] Step 202: mixing phosp...

Embodiment 3

[0066] Embodiment three of the present invention provides another kind of nano-microbe organic-inorganic compound fertilizer, comprising:

[0067] By weight, 0.15-0.2 parts of Bacillus megaterium, 0.15-0.2 parts of Bacillus jelly-like, 0.15-0.2 parts of Bacillus subtilis, 150-200 parts of water, 60-80 parts of phosphogypsum, 65-75 parts of superphosphate , 60-80 parts of fly ash, 10-20 parts of montmorillonite, 5-40 parts of layered silicate, 80-200 parts of humic acid.

Abstract

The invention relates to the agricultural field and the environment-friendly field, in particular to nano microorganism organic and inorganic compound fertilizer and a production method thereof. The fertilizer comprises the following components in parts by weight: 5 to 40 parts of layered silicate, 0.1 to 0.25 part of bacillus megaterium, 0.1 to 0.25 part of bacillus mucilaginosus, 0.1 to 0.25 part of bacillus subtilis, and 0.1 to 0.25 part of base fertilizer containing nitrogen element, potassium element and phosphor element, wherein the nitrogen element, the potassium element and the phosphor element are 6-18% of total weight of the base fertilizer. The production method comprises the following steps: strains of the bacillus megaterium, the bacillus mucilaginosus and the bacillus subtilis are cultivated respectively to obtain strains in a spore state; the base fertilizer is mixed and smashed; and the smashed base fertilizer, the strains in the spore state and the layered silicate are mixed, pelletized and dried. The fertilizer can provide the nutrition needed by crops, and can decompose nitrogen fertilizer, potassium fertilizer and phosphor fertilizer adsorbed and fixed in the soil, so that soil damage is avoided.

Description

technical field [0001] The invention relates to the fields of agriculture and environmental protection, in particular to a nano-microbial organic-inorganic compound fertilizer and a preparation method thereof. Background technique [0002] Existing fertilizers mainly include inorganic fertilizers, organic fertilizers, and compound fertilizers. Although these chemical fertilizers can increase the yield of crops, long-term application is also harmful to the soil. The main reason is that only part of the applied fertilizer is directly absorbed by the plants, and the other part is absorbed and fixed by the soil. When the absorbed and fixed substances are excessive, especially phosphorus and potassium fertilizers, it will destroy the natural balance of the soil and the aggregate structure of the soil, which will lead to soil compaction and soil fertility. fall, causing severe damage to the soil. For example, when there is too much phosphate fertilizer in the soil, it will combi...
