The invention discloses bacillus megaterium and an application thereof, and belongs to the field of microorganisms. A plant growth promoting bacterium (bacillus megaterium JX15) is collected in the China General Microbiological Culture Collection Center on Dec.20, 2011, the class name is bacillus megaterium and the collection number is CGMCC No.5622. The bacillus megaterium has the beneficial effects that a strain can produce indoleacetic acid with high yield, can be used for nitrogen fixation and can grow by using sparingly-soluble phosphates as phosphorous sources, so as to improve the utilization rates of fertilizers, promote plant root development and absorption of the fertilizers, and increases the contents of soil mineral nitrogen and available phosphorus; the strain has a good effect on promoting growth of peanuts; the high-yield indoleacetic acid promotes the growth and the development of the peanuts; and the nitrogen and phosphate fertilizer utilization rates of the peanuts are relatively high due to the increasing of the contents of the soil mineral nitrogen and the available phosphorus.
