Abstract：Nitrogen content and accumulation in different organs of bamboo including leaves, branches and culms was studied with the three typical bamboo species in Zhejiang Province, i.e., Phyllostachys prominens,Pleioblastus amarus and Dendrocalamopsis oldhami. The results showed that the nitrogen contents in the different organs of the three bamboo species could be ordered by leaves > branches > culms, and nitrogen content decreased with the age of bamboo. Nitrogen content in 3-year-old D. oldhami was significantly higher than that of Ph. prominens and P. amarus (P<0.05).Nitrogen content in culms were in the order of D. oldhami > P. amarus > Ph. prominens, and there were significant difference among 2-and 3-year-old bamboo culms of the three species (P<0.05). Nitrogen accumulation of the different bamboo species were ordered by D. oldhami > P. amarus > Ph. prominens, and the nitrogen storage was 370.28, 254.72 and 113.03 kg/ha, respectively. Nitrogen use efficiency was showed as Ph. prominens > P. amarus > D. oldhami, and the nitrogen element that was needed per ton of dry matter of the three bamboo species were 6.37, 6.53 and 7.96 kg, respectively.
