Abstract

The invention discloses a multifunctional microbial fertilizer and a preparation method thereof. The preparation method of the multifunctional microbial fertilizer comprises the following steps: preparing a culture medium; culturing azotobacter chroococcum, bacillus mucilaginosus, bacillus megaterium and bacillus subtilis in the culture medium until maturing, and then culturing for 20-24 hours, so as to obtain each bacterium solution; mixing the obtained bacterium solutions according to a volume ratio of (1-2) to (0.5-1) to (0.5-1) to (0.5-1), adding sterilizing turf for absorption, and carrying out solid fermentation for 18-24 hours; and after the solid fermentation is finished, grinding. According to the multifunctional microbial fertilizer, nitrogen-fixing bacteria are capable of automatically fixing nitrogen in air and converting nitrogen into necessary nitrogen fertilizers of crops; phosphorus decomposing bacteria and potassium decomposing bacteria are capable of decomposing great amounts of insoluble phosphate and potassium deposited in soil into a phosphate fertilizer and a potassium fertilizer which can be reabsorbed and reused by the crops; disease-resistant bacteria are capable of inhibiting bacteria, so that diseases can be reduced; furthermore, by virtue of microorganisms, heavy metals in soil can be reduced and purified, or the toxicities of the heavy metals can be reduced; and after the microbial fertilizer is applied to the soil, beneficial microorganisms are increased, and harmful microorganisms are obviously reduced.

Description

1. Technical field [0001] The invention belongs to the technical field of biological fertilizers, and in particular relates to a multifunctional microbial fertilizer and a preparation method thereof. 2. Background technology [0002] At present, domestic microbial fertilizers mainly include the following types: (1) rhizobia fertilizers; (2) nitrogen-fixing bacteria fertilizers; (3) soil phosphorus activators; (4) silicate bacterial fertilizers; (5) compound microbial fertilizers, etc. . The above-mentioned fertilizers not only have a single fertilizer effect, but also cannot solve the problem of soil heavy metal pollution, and are difficult to meet actual needs. 3. Contents of the invention [0003] The purpose of the present invention is to provide a multifunctional microbial fertilizer and a preparation method thereof. The multifunctional microbial fertilizer not only has high fertilizer efficiency, but also can effectively solve problems such as soil heavy metal pollut...
