| 中文摘要 | A greenhouse experiment was conducted to explore whether additional nitrogen (N) supply could enhance carbon (C) accumulation, and phosphorus (P) use efficiency (NUEp) of Sophora davidii seedlings under dry conditions. Two-month-old seedlings were subjected to a completely randomized design with three water (80, 40 and 20% water field capacity (FC)) and three N supply (N0: 0, Nl: 92 and Nh: 184 mg N kg(-1) soil) regimes. Water stress decreased C, N and P accumulation, NUEP, N and P uptake efficiency (NUtE(N) and NUtE(P)) regardless of N supply. The S. davidii seedlings exhibited strong responses to N supply, but the responses were not consistent with the various N supply levels. Nl increased C, N and P accumulation, and improved NUEP, NUtE(N) and NUtE(P) in the same water treatment. In contrast, Nh did few or even depress effects on C, N and P accumulation, and NUEp, although NUtE(N) and NUtE(P) increased with Nil in the same water treatment. Even so, NUEN decreased with increase of N supply in the same water treatment. The results suggested that appropriate or low N supply should be recommended for S. davidii seedling establishment in dry environment by improving C accumulation and NUEP. (C) 2009 Elsevier Ltd.
