Plantation poplar is one of the most important resources for wood industry, its utilization field is vast. The wettability of Populus tomentosa with different drying methods was judged by measurement of contact angle using distilled water in this paper. The results showed that the specimens from conventional drying have the biggest contact angle, and the air dried have the smallest contact angle, air dried lumbers have a better wettability than the kiln dried. The changes of contact angle in a period of time showed wettability sequence of lumber with different drying methods: air drying > high temperature drying > conventional drying. The basic property for high value-added plantation poplar lumber products was provided to the wood industry.
