1. A preparation method for a ceramic plate with a colorful flowing cloud surface decoration effect, comprising: pressing and forming a ceramic base material to obtain a green body of the ceramic plate; applying a ground glaze on a surface of the green body to cover the base color and defects of the green body; applying a cover glaze on the surface of the green body after applying the ground glaze, wherein the cover glaze contains 0.2 wt % to 0.7 wt % of a coloring metal oxide to make the coloring bright, in addition to the coloring metal oxide, the chemical composition of the cover glaze further includes, in percentage by mass: loss on ignition: 6.5% to 7.5%; SiO2: 48% to 53%; Al2O3: 8% to 10%; TiO2: 7% to 8%; CaO: 10% to 13%; MgO: 2.0% to 3.0%; K2O: 3.0% to 4.0%; and ZnO: 9% to 11%, the specific gravity of the cover glaze is 1.55 g/cm3 to 1.58 g/cm3, and an application amount of the cover glaze is 380 g/m2 to 410 g/m2; applying a roller effect glaze on the surface of the green body after applying the cover glaze for roller-printing, so as to print cloud effect patterns on the surface of the cover glaze, wherein the chemical composition of the roller effect glaze includes, in percentage by mass: SiO2: 47% to 50%; Al2O3: 7% to 9%; TiO2: 12% to 13%; CaO: 10% to 13%; MgO: 2.0% to 3.0%; K2O: 2.0% to 3.0%; Na2O: 3.0% to 4.0%; and ZnO: 10% to 12%, the specific gravity of the roller effect glaze is 1.28 g/cm3 to 1.32 g/cm3, an application amount of the roller effect glaze is 40 g/m2 to 50 g/m2, and an initial melting temperature of the cover glaze is 5° C. to 10° C. higher than that of the roller effect glaze to ensure that contact edges of the roller effect glaze and the cover glaze have a transitional permeability effect with undulating patterns; and drying the green body after roller-printing and firing in a kiln, wherein a metallic liquid luster is sprayed on the surface of the green body at 750° C. to 850° C. in the process of firing to form a metallic liquid luster film, an application amount of the metallic liquid luster is 50 g/m2 to 60 g/m2, and a thickness of the formed metallic liquid luster film is 5 mm to 6 mm.
