The invention discloses a manufacturing method of novel spliced plates. The method includes the steps that a wood block is cut into single plates equal in length, width and thickness in a rotary manner; the single plates are graded according to appearance defects of the single plates, the single plates with no defects on the single faces are classified into class-A plates, and the single plates with defects on the two faces are classified into class-B plates; the classified single plates are dried, and the water content is controlled to be 10%-14%; one or more class-B plates are clamped between every two class-A plates in a stacking and gluing manner, and wood grains of the class-B plates and wood grains of the class-A plates are arranged in the same direction; hot-pressing treatment is carried out, the plates are cured for 20 h-30 h at room temperature, and multi-layer plywood is formed; the thickness is determined with rough sanding; the plywood is sawn into battens with the preset width through a sawing machine to achieve batten splitting; the battens are spliced in the same direction according to the sawing sequence of plywood and the wood grain, and patterns of products are the same as those of the plywood which is not sawn; and finally fine sanding is carried out, and the spliced plates are obtained. The invention further discloses a novel spliced plate. By the adoption of the method, working procedures can be simplified, the outturn percentage is increased, and the spliced plates have the beneficial effects of being high in appearance level and strength.
