Orthogonal experimental design was adopted to obtain the reasonable vacuum-pressure in the preservative-treated process the wood of Pinus massoniana, a fast-growing tree species. The results indicated that preservative concentration and pressure were the main factors in influence the wood preservative retention. The influence of preservative concentration reached extremely significant level, the influence of pressure, pressure duration reached significant level. The optimal parameters were 0.5 percent preservative concentration, 1.2 MPa pressure, 1 h pressure duration, 30 minutes pre-vacuum duration.
