A laboratory decay experiment was conducted on bamboo（Phyllostachys pubecens）with 13 kinds of preservatives that were used and compared.The results showed that,1)The effects of different preservatives improved when the retention level was increased.2)The decay resistance of ACQ-B was the best among all the five ACQ preservatives,and was followed by ACQ-D.At a low retention,the resistance of ACQ-C to white rot was the worst,and the weight loss rate reached about 6%.3)Among the four CuAz formulations,CuAz-1 showed the best resistance to white rot,while CuAz-2 was the worst.But,there was little difference for the resistance to brown rot.4)The decay resistance of ACQ and CuAz were close to CCA,and obviously superior than organic acid preservative.
