Abstract：In order to elucidate the nutrition of Camellia oleifera at pollination and fertilization stages, the contents of mineral elements were determined by auto discrete analyzers and atomic absorption spectrophotometer, and the change in the contents of mineral elements was studied and analysed under the condition of self- and cross-pollination. The results are showed that nine kinds of mineral elements contents were of “S” or “W” type curve changes at the pollination and fertilization stages of Camellia oleifera. N, K, Zn, Cu, Ca, Mn element content changes showed “S” curve under the self- and out-crossing, the content of N reaching the highest was 3.445 8 mg·g-1 in self-pollination of 20 d; K content reaching the highest at the cross-pollination 20 d was 6.275 5 mg·g-1; Zn content in self-pollination of 10 d reaching the highest was 0.070 5 mg·g-1; Cu content in the cross-pollination of 5 d up to the highest was 0.061 0 mg·g-1; Ca content in the cross-pollination of 15 d up to the highest was 3.714 5 mg·g-1; the content of Mn reaching the highest in self-pollination 30 d was 2.161 5 mg·g-1. Fe, P, Mg element content changes was of “S” type curve in selfing and was of “W” type curve in outcrossing, Fe content in the self-pollination 10 d up to the highest was 0.453 0 mg·g-1; P content in self-pollination of 20 d reaching the highest was 6.731 8 mg·g-1; the content of Mg up to the highest in self-pollination 25 d was 2.724 0 mg·g-1. The results can be used as a reference for spraying foliar fertilizer, and improving seed setting rate and yield in Camellia oleifera.
