摘　　要：为了探究和推广油茶发展的"绿色"集约经营模式,促进油茶增产增收,以6年生"长林"系列油茶为研究对象,分别设配方肥、复合肥、有机肥3种施肥处理,以不施肥作对照,研究了不同施肥处理对"长林"系列油茶春梢生长、果实产量和果形指数等方面的影响。结果表明:不同类型的肥料在短期内对油茶春梢粗度、长度及油茶果实产量的影响不明显,但对油茶当年生叶片的SPAD值有影响,3种施肥处理的SPAD值明显大于对照,其中以配方肥的效果为最好,3种施肥处理的油茶果形指数均值均大于对照。In order to study and promote the green intensive management mode of Camellia oleifera development and to increasing production and income, taking 6-year-old Chang-Lin series of C. oleifera as research object, effects of different fertilizer treatments on spring shoot growth, fruit yield and fruit shape index in C. oleifera were researched, namely formula fertilizer, compound fertilizer, organic fertilizer and CK without fertilization. The results show that different types of fertilizers have no significant effect on thickness and length of spring shoots as well as fruit yield in the shoot term, but they affect the leaf SPAD value in the same year, the leaf SPAD value and fruit shape index of three kinds of fertilization are significantly greater than CK, and effect of formula fertilizer is best.
