Abstract: The measurement of the physicomechanical properties of 9 plantation poplar I-69(Populus deltoides CV.I-69/55)woods under fertilization and seasonal flooding showed that compared with no fertilization,fertilization increased the ring width,static modulus of elasticity,and compressive strength parallel to the grain by 0.99%(P>0.05),2.73%(P<0.05)and 1.06%(P<0.05),while decreased the air-dry radial,tangential,volumetric shrinkage,oven-dry radial,tangential,volumetric shrinkage,basic density,MOR,and dynamic modulus of elasticity by 4.2%,7.7%,6.6%,15.6%,6.3%,11.1%,2%,1.79% and 8.13%,respectively.Seasonal flooding decreased the basic density,air-dry radial,tangential,volumetric shrinkage,oven-dry radial,tangential,volumetric shrinkage,MOR,MOE,and compressive strength parallel to the grain by 5.5%,11.1%,9.2%,9.6%,16.7%,10.9%,8.5%,24.29%,18.18% and 16.81%,respectively,in comparing with non-flooding.
