A disclosed method for growing calcium-doped YBCO quasi monocrystal from an embedded seed crystal comprises the following steps: a) preparing a powder of Y123 phase; b) preparing a precursor of the embedded seed crystal; and c) putting the precursor of the embedded seed crystal in a growth furnace for growing calcium-doped YBCO quasi monocrystal in a melt texture growth manner, wherein the precursor is a cylindrical precursor prepared by uniformly mixing and compacting Y123, CaCO3 and CeO2 according to a mass ratio of 1:(0-15)%:(0.3-1.5)%, and the embedded seed crystal means that the induction growth face of the seed crystal is fixedly horizontally embedded into the precursor. By embedding the seed crystal into the calcium-doped YBCO precursor, the dissolving and the diffusion of rare earth elements in thin film seed crystal is effectively inhibited, the structural integrity of the film at high temperature is guaranteed, the thermal stability of the film is improved, and thus the preparation of the calcium-doped YBCO quasi monocrystal is facilitated.
