Detail characteristics of reed are analyzed, and the effect of density and adhesive content on physical and mechanical properties of reed medium density fiberboard (MDF) are investigated. The results show that the yield rate of reed fiber reached 87.4%, and the physical and mechanical properties of reed MDF improve, but a upward trend in thickness swelling rate of water absorption (24 hours) appears with the increase of density. Under the condition of density being equal to or higher than 0. 85g/cm~3 and the content of UF resin being 12% or 14%, the reed MDF prepared possesses good physical and mechanical properties.
