In this paper,the cultivation experiment of Toona sinensis timber forests was conducted on the different varieties,density and fertilizer.The results showed that the ground diameter of T.sinensis from Jiujiang provenance growing fastest in afforestation at second year,annual average of 2.016 cm;but the tree high growth as medium density of 2 m×2 m was the largest,with an average annual growth rate of 0.606 m;The increment of ground diameter,tree height and crown diameter was the largest under each applied with 0.75 kg compound fertilizer.It would be in avail for young forest growth under adopting Jiujiang provenance,plant density at the beginning of the 2 m×1.5 m and 0.75 kg compound fertilizer each applied.The study result can provide scientific basis for cultivation of T.sinensis timber forests in Jiangxi Province.
