The invention discloses a zinc alloy implant with a calcium-zinc-phosphorus modified layer and a preparation method and application of the zinc alloy implant, the Ca-Zn-P modified layer presents irregular petal-shaped block masses formed by stacking flaky crystals, the flaky crystals are tightly arranged, the irregular petal-shaped block masses are loosely distributed on the surface of a zinc alloy matrix, and the surface of the matrix is coated with a calcium-zinc-phosphorus modified layer. The main phase composition of the calcium-zinc-phosphorus modified layer is CaZn2 (PO4) 2.2 H2O; according to the zinc alloy implant with the calcium-zinc-phosphorus modified layer, the adhesion and osteogenesis of cells can be promoted by virtue of the microstructure characteristics of the zinc alloy implant with the calcium-zinc-phosphorus modified layer; the thickness of a single lamellar crystal is nano-scale, the length of the single lamellar crystal is micron-scale, the nano-scale lamellar crystal can induce the for
