In order to use shrub materials to produce wood based panels reasonably,pH value,buffering capacity and curing time of 6 main shrub species in the north western China were measured.Testing results indicated that the 6 species showed little acidity with pH values between 6.03 to 4.54,that the alkali buffering capacities were between 0.314 to 0.222 mmol and acid buffering capacities were between 0.105 to 0.040 mmol.
