Abstract: Dendrocalamopsis oldhami is an important dual-use product providing wood and bamboo shoots. To improve sustainable bamboo management for long-term benefits, the uptake, accumulation, and distribution of the main nutrients in the above-ground parts of D. oldhami were studied. In January 2013, plant samples of different aged leaves, branches, and culms of D. oldhami were collected in Cangnan, Zhejiang Province to analyze nine elemental nutrients, namely N, P, K, Mg, Ca, Fe, Mn, Zn, and Cu. Results showed that the nutrient content was leaves > branches > culms. Total nutrient accumulation in above-ground parts was 621.07 kghm-2 with culms (344.04 kghm-2) > leaves (158.81 kghm-2) > branches (118.22 kghm-2). The nutrient accumulation amount was N>K>P>Mg>Ca>Fe>Mn>Zn>Cu. Maximum N accumulation was 354.28 kg hm-2 accounting for 57.0% of the total accumulation in the above-ground parts. Since the net organic production of a D. oldhami forest required 12.92 kg of the main nutrition elements (N, P, K, Ca, Mg) per ton with 58.0% of that being N, to promote growth an increase of N fertilizer is required.
