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 camellia 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.
