The invention discloses a method for producing a stable high-strength solid-wood composite board, which is characterized in determining and pre-treating of raw materials on each layer. A high-quality hard wood thin plate is used as a face (1) plate, a medium soft veneer is used as a core (2) plate and a relatively thick fast-growing wood material is used as a bottom (3) plate, at least two isosceles trapezoid-shaped grooves are formed on the bottom plate, trapezoid-shaped wood strips (4) fitting well with the grooves are inserted in the grooves, and the three plates are bonded together. After the three plates are laminated, the bonding strength, mechanical strength and deformation resistance of the composite board in the transverse direction are increased, so as to improve the stability. The invention has the advantages of providing a new approach to combined use of high-quality wood and fast-growing wood, increasing the application range of composite boards and increasing the added value of products.
