This paper studied the wettability of H2O，phenol formaldehyde adhesive (PF)，urea- formaldehyde adhesive (UF) and modified soy- based adhesive (MSA) in tangential sections of moso bamboo (Phyllostachys Pubescen) with different pole heights. Through measuring contact angles of four kinds of liquids on the tangential sections of moso bamboo，the dynamic wetting model was built，and the effects on the wettability of these liquids on the tangential sections with different pole heights and the differences of the wetting performance of these liquids on the tangential section of moso bamboo were analyzed.
