以2年生油茶( Camellia oleifera)扦插苗为试验对象，对其在不同水分(土壤含水量分别为：28%~31%、15%~18%、9%~12%)和不同浓度氮素(0 g/株、0．375 g/株、0．750 g/株)条件下，通过生理生化试验方法，测定油茶扦插苗叶片、根部碳、氮、磷、钾的含量。结果表明：在土壤水分胁迫条件下，施加高氮(0．750 g/株)更有利于苗木在土壤水分胁迫条件下碳、氮、磷、钾积累。在土壤水分轻度胁迫条件下，施加低氮、高氮均促进叶片碳、氮积累，不能促进叶片磷、钾的积累；在土壤水分重度胁迫条件下，施加低氮、高氮促进叶片氮、磷、钾的积累，不能促进碳的积累。在土壤水分轻度胁迫条件下，施加高氮促进根部碳、氮、磷、钾积累，施加低氮仅促进氮的积累；在土壤水分重度胁迫条件下，施加氮素只促进根部氮的积累，不能促进根部碳、磷、钾的积累。

The content of C, N, P and K from leaves and roots of 2-year-old Camellia oleifera cutting seedling was measured under different water conditions ( soil moisture content were from 28% to 31%, from 15% to 18%, and from 9% to 12%) and nitrogen conditions (0, 0. 375, 0. 750 g per seedling) by physiological and biochemical tests. Results showed that it was better for C, N, P and K accumulation under soil water stress condition to apply high nitrogen (0. 750 g per seedling) . Low and high nitrogen application made for C and N accumulation of leaves, but had no effect on P and K accumulation under light water stress. Low and high nitrogen application made for N, P and K accumulation of leaves, but had no effect on C accumulation under serious water stress. High nitrogen application made for C, N, P and K accumulation of roots, but only N accumulation with low nitrogen application under light water stress. Nitrogen application made for N accumulation of roots, but had no effect on C, P and K accumu-lation under serious water stress.
