In order to improve the utilization rate of wood and solve the shortcomings of low density, low strength, and easy shrinkage deformation of artificial fast-growing forest. In this study, the artificial fast-growing poplar was taken as the research object, and the unique mineral hexagonal stone in Inner Mongolia Autonomous Region was used as the modified material. The hexagonal stone was impregnated into the wood by vacuum pressurized impregnation modification technology, and then the properties of modified wood were tested and characterized. The results showed that the optimum impregnation times of poplar wood modified by hexacyclic stone were 8 times. The single impregnation process was vacuum impregnation for 120 min, atmospheric pressure impregnation for 5 min, and then absolutely dried. The average weight gain rate and liquid absorption rate of the modified wood were 15.33% and 146.37%, respectively. The air-dry density and total dry density of the modified wood were 23.25% and 21.95% higher than those of the raw materials, which provided new ideas for the preparation and utilization of modified wood.
