Claim:
1. A wet process of fabricating fiber wall panels with a decorative convex-concave pattern surface, comprising the steps of: 1) providing a grass slurry, being made by a process comprising steps of (a) breaking dried grass plant stalk or lawn grass to lengths of 1-5 cm, (b) soaking the grass plant stalk or lawn grass from step (a) for 30-72 hours, and (c) rubbing and grinding the plant stalk or lawn grass from step (b) into the grass slurry using a rubbing and grinding thread separator; 2) providing a fiber slurry separate from the grass slurry; 3) making a mixed slurry, comprising mixing the fiber slurry and the grass slurry, at a weight ratio of the dry ingredients of the fiber slurry to the dry ingredients of the grass slurry of 1.0˜1.5 to yield a raw material and adding water to the raw material for dilution to yield the mixed slurry in which the dry weight of the raw material accounts for 3.0-5.0% by weight; 4) storing the mixed slurry, comprising pouring the mixed slurry into a slurry storage tank, and adding water for dilution to yield a final slurry in which dry weight of the raw material accounts for 0.3-0.6% by weight; 5) forming a wet blank, comprising transferring the final slurry into a mold for cold pressing, dewatering, and forming, to form the wet blank the weight of which is 1.0-10.0% of the weight of the final slurry added in the mold; and 6) forming a fiber wall panel, comprising transferring the wet blank into a hot pressing mold to perform hot pressing for 18-60 seconds at a pressure of 0.5-5.0 Kg/cm
