The invention discloses a preparation method and application of a bio-based flame retardant with phytic acid as a base plate, and the preparation method comprises the following steps: diluting a phytic acid solution into a diluted phytic acid solution, dropwise adding the diluted phytic acid solution into an R solution formed by mixing organic compounds, and keeping magnetic stirring to obtain an intermediate product; and adding the intermediate product into a reaction kettle for reaction, cooling to normal temperature after the reaction is finished, carrying out suction filtration on the product, washing with deionized water, and carrying out vacuum drying to obtain the bio-based flame retardant. The bio-based flame retardant prepared by the invention belongs to a biomass material, the preparation process is non-toxic, solvent-free, green and environment-friendly, the preparation process is simple and easy to operate, the yield is high, the process controllability is good, and industrial production is easy;
