Abstract：The paper mainly studies the growth law of Phyllostachys nuda from shoots to young bamboo as well as the length change law of culms from the base to the first node. The results showed that the height growth showed the slow-fast-slow law, which was consistent to the logistic equation. The bamboo could reach the maximum growth rate about 12 days after the shooting. The first to fourth node above the base were the short nodes, with the average length at 6.9 cm; the 5th to 12th node were the middle nodes with the average length at 16.0 cm; the 13th to 23rd nodes were the longest with the average length at 23.2 cm and the nodes after the 24th node has the middle length again at 15.1 cm. It is suggested that the bamboo forest management should be enhanced properly in accordance to the height growth law so as to improve the management benefits.
