摘　　要：采用随机区组田间试验设计,以油茶优良无性系幼林为试材,研究了不同氮磷钾配方施肥对油茶幼树营养生长及叶绿素含量的影响。结果表明配方施肥对油茶优良无性系幼树树高、冠幅、梢长生长均有不同程度的促进作用,但不同的配方施肥和施肥量对油茶幼林的营养生长及叶绿素含量有很大的差异性,其中处理7油茶幼树各指标增量极显著大于其它处理。本试验氮、磷、钾(N∶P2O5∶K2O)最适配方为10∶5∶2。In this paper, studies were made of effects of different amount of N ,P, K fertilizer on the sapling growth and chlorophyll content of superior clones of Camellia oleifera by the randomized block design in the field experiment. The results showed that combined fertilization had effects on the height, crown width and shoot growth of Camellia oleifera saplings to different degree. However, the sapling growth and chlorophyll content of young Camellia Oleifera forest were very different under the condition of different ration of fertilizer and application. Among them, the effect of treatment 7 was significantly greater than that of the other treatments. The optimum ratio of N,P,K （N： P2O5： K2O） was 10： 5：2 in this test.
