On the basis of theoretical calculation,the volumetric ratio of wood substances towater and air for the wood in basic density 0.36g/cm￣3 at 120% moisture content is about 1 :1:1.Therefore,the free water in wood will all be squeezed out as the volumetric squeezingratio of the wood reached 66%. Based upon this consideration,squeezing tests were made forgreenwood veneer of fast grown loblolly pine(pinus taeda)and poplar I-69(Populus del-toides Bartr cv." Lux " I-69/55)in various squeezing ratios by using various types specialgrooved plates. The moisture content of 2.02mm thick greenwood veneer of poplar I-69 wasdecreased remarkably after squeezing in 70%squeezing ratio and the distribution of moisturecontent of the veneer got more uniform. The differences among moisture contents of the sam-ples taken from different parts of the veneer from the same bolt got smaller remarkably alsoafter squeezing.More water were squeezed out of 2.38mm and 3.33mm thick greenwood ve- neers of loblolly pine in 60%squeezing ratio than in 40%squeezing ratio,and greater uni-form distribution of moisture content of the veneers were obtained in the former case. It wasevident that squeezing with grooved plates could effectively make the moisture content ofgreenwood veneer lower and more uniform distribution. It was also found that squeezing withvarious type of grooved plates showed different results.
