摘　　要：以油茶(Camellia oleifera Abel)为试验材料,研究了施用氮、磷、钾肥对油茶生长、产量及油茶叶片N、P、K、Fe、Mn、Cu、Zn等营养元素含量的影响。结果表明,施肥可促进油茶树高、冠幅和地径的生长,影响顺序为N>P>K。施肥后、油茶叶片中Fe、Mn、Cu呈上升趋势,N、P、K、Zn整体上呈下降趋势。叶片中N、P、K元素之间呈正相关关系,这3种元素与Fe、Mn、Cu呈负相关关系;元素Fe、Mn、Cu之间呈正相关,但这三者与元素Zn呈负相关。The effects of fertilization on the growth, yield and dynamic change of N, P, K, Fe, Mn, Cu, Zn in the leaves of oil camellia were studied. The results showed that fertilization could increase the height of oil camel- lia tree, crown breadth and ground diameter growth, and the influence order was N 〉 P 〉 K. After fertilization, the content of Fe, Mn, Cu in the leaves showed ascendant trends, N, P, K and Zn declined on the whole. There are positive correlations between N, P, K, and between Fe, Mn, Cu in the leaves. The contents of N, P and K correlate negatively to Fe, Mn, Cu, and Fe, Mn and Cu correlate negatively to Zn.
