The invention discloses a production method of a decorative rock plate with naturally-opened textures. The production method comprises the following steps: A, preparing green body powder according to a conventional method; b, preparing slurry for a digital slurry distribution system; c, forming; d, drying the green body; e, digital slurry distribution; f, drying again; g, pattern decoration; h, spraying glaze stripping ink; i, applying a transparent plane material; j, drying for the third time; k, firing; and L, edge grinding is carried out, and the decorative rock plate with the naturally-pushed-aside textures is obtained. Water-based ceramic slurry can be applied in a positioned mode according to the preset pattern texture, the obvious concave-convex three-dimensional texture is achieved, the poking glaze ink and the transparent plane material are matched to form poking effect three-dimensional texture, lines of slurry for a digital slurry distribution system can be arranged at will, and the production efficiency is improved. The matching of a plurality of nozzle arrays enables the texture of the imitated natural stone formed by slurry distribution to be clearer and more vivid, three-dimensional and fine, the pattern and line effect to be richer, and the gradual transition effect to be good.
