In order to further research bamboo cultivation and expand its application field, air-dried density and mechanical properties of Moso bamboo from the 2 plantations under the same site condition were measured and analyzed by using the national standard The Testing Methods for Physical and Mechanical Properties of Bamboo (GB / T 15780-1995). And the single linear regression analysis was carried out. The results showed that air-dried density and mechanical properties of the 2 kinds of Moso bamboo increase with the age increasing, and at the same age, those of Moso bamboo from the seedling plantation are much higher than those from the common plantation afforested by transplanting, in other words, Moso bamboo from the conventional plantation reaches a stabilization the at age of 4, while that from the seedling plantation reaches a stabilization at the age of 6 or more. There is a positive correlation between air-dried density and mechanical properties of the 2 kinds of bamboo.
