摘  要:
【Objective】In order to further processing and use of Exbucklandia populnea and increase itsadded value. 【Method】The physical and mechanical properties and processing properties of the wood werestudied by qualitative and quantitative methods. 【Result】The results showed that the average basic densi-ty,air dry density and total dry density of the wood were 0. 442 g/cm3、0. 525 g/cm3;0. 525 g/cm3 respec-tively. The radial and chordal shrinkage rates of the whole stem are 3. 5% and6. 4% respectively,the com-pression strength of the parallel grain is 43. 2 MPA,the flexural strength and modulus of elasticity are95. 1 MPa and 7590 MPA respectively. 【Conclusion】 The wood has good mechanical processing perform-ance and is suitable for cutting and planing thin wood. Its comprehensive properties reach the middle gradeand belong to the second class wood.
