The invention relates to a production processing method of homogeneous carbonized wood of paulownia wood. The production processing method comprises the following steps of cutting and sawing, degreasing, drying, re-damping, stacking, feeding into a kiln, temperature rising, carbonizing, temperature lowering, and delivery out of the kiln. The production processing method has the beneficial effects that firstly the paulownia wood is degreased, so good foundation is laid for the homogeneous carbonizing; when the wood is fed into the kiln, the wood is coated by kaolin, air is completely isolated, and the uniform carbonizing effect is realized; after the kiln is sealed, the carbonizing temperature is integrally lowered, the carbonizing time is extended, the uniform carbonizing of the paulownia wood from exterior to exterior is guaranteed, and all parts of the paulownia wood have the good moisture absorbing property, size stability, mechanical property, anti-corrosive property, hardness and compressive strength, adhesion property, and surface coating property, especially same color property; by improving the degreasing method, the carbonizing auxiliary material, the carbonizing temperature and the carbonizing time, the carbonized wood can reach better homogenous effect; the adhesion effect is improved, and the application value and economic benefits of a product are increased.
