Cornstalk particles were compressed in a die under different conditions of temperature, pressure and moisture content, and then the creep-time curves were drawn and analyzed. Variance of analysis of the results showed that pressure was the dominant factor affecting the creep of cornstalk particles. The creep reached the highest point under the pressing conditions of 5.6 MPa, 120 ℃ and moisture content of 12%. If pressure and moisture content parameters held constant, the creep at the temperature of 150℃ would be lower than that at 120℃ and 170℃. While fixing temperature and pressure parameters,the creep at moisture content of 14% was less than that at 12% and 16%.
