The invention discloses a method for manufacturing a concave-convex rod rectangular environment-friendly bushing plate. According to the key points of the technical scheme, the method comprises the following steps of: pressing concave-convex rod ceramic mud with an air purification function to form a blank body of the concave-convex rod rectangular environment-friendly bushing plate, wherein the blank body is a rectangular bowl-shaped shell, and the upper side of a bottom plate is provided with a reinforcing rib and a through hole; naturally drying, and then making the naturally-dried blank body enter a slow drying stage, an intermediate temperature sintering stage and an intermediate and high temperature sintering stage; cooling the sintered blank body, and cleanly polishing; and packaging to obtain a finished concave-convex rod rectangular environment-friendly bushing plate. The concave-convex rod rectangular environment-friendly bushing plate contains a large quantity of micro-pores and activated carbon, has the functions of drying agents and can effectively adsorb harmful substances such as formaldehyde, ammonia, benzene, peculiar smell and the like in the air, so that the environment is protected, and the body health of people is increased; and the concave-convex rod rectangular environment-friendly bushing plate can be directly arranged in various containers for accommodating articles such as food, tea or rice, flour and the like and is used for fulfilling the aims of moisture prevention, mildew prevention, insect prevention and environment friendliness.
