An Experimental Study of the Density of Toona ciliata Plantations

Toona ciliata Roem was a precious timber species with superior quality and fast growing characteristics, and it was large-scalely planted in Sichuan. The single-factor experiment was designed to investigate the growth effects of the primary density and the intermediate cutting in 10 years old forest. The results showed that the effect of the primary density was not significant in three years after afforestation, and a reserve density of 1 600 trees per hectare after intermediate cutting in 10 years old forest of Toona ciliata was suitable.
