Abstract

Physical and mechanical properties of clone Chinese fir wood and seedling are studied and compared .Tested wood for both is of nine-year-old , from Kaihua Forest Farm of Zhejiang Province .Results of 15 clones show that some physical and mechanical parameters of clone Chinese fir wood are superior to seedling , and the other inferior to .Air-dry density of clone Chinese fir wood is 0.340 g cm-3 , basic densi ty 0.280 g cm-3 , coefficient of radial shrinkage 0.131 %, coefficient of chordwise shrinkage 0.217 %, coefficient of volumetric shrinkage 0.401 %,bend strength 44.355 MPa , bend elastic modulus 8.296 GPa , and impact ductility kJm-2 .
- Chinese fir (Cunninghamia lanceolata),
