Disclosed are a floatable three-dimensional (3D) hollow microsphere material, and its preparation method and use in soil cadmium reduction, belonging to the field of regeneration of contaminated soil. The preparation method includes: mixing polyvinyl alcohol, sodium alginate, ethylenediaminetetraacetic acid, saponin, and at least one of modified rectorite and unmodified rectorite, to obtain a mixed material, wherein the modified rectorite includes at least one of formamide-modified rectorite and sodium humate-modified rectorite; and mixing the mixed material with a cross-linking agent solution, and performing cross-linking on a resulting mixture to obtain the floatable 3D hollow microsphere material. The floatable 3D hollow microsphere material is applied to moist soil to adsorb and remove heavy metal elements.
