摘　　要：[Objective] This study aimed to investigate the optimal component of culti- vation medium for container seedling raising of Camellia oleifera. [Method] In the application of container nursery technology of Camellia oleifera grafting in emergent stocks, yellow clay soil, surface soil of pine forest, decomposed edible fungus, peat soil, dung and dirt were mixed by different proportions into five formulae as nursery substrates, with garden soil as the control, in order to investigate the influences of various substrates on the growth of annual Camellia oleifera container seedlings by using randomized block design based on variance analysis and multiple comparisons, and to screen the optimal substrate formula for container nursery of Camellia oleifera. [Result] The influences of different substrates on the transplanting survival rate, seedling height, basal diameter, height-diameter ratio and lateral root length of Camellia oleifera container seedlings were significantly different. Various growth indi- cators of Camellia oleifera container seedlings cultivated in the substrate containing 40% of yellow clay soil ＋ 15% of surface soil of pine forest ＋ 20% of decomposed edible fungus ＋ 20% of peat soil ＋ 5% of dung and dirt exceeded that of the control and other substrate formulae, which could be used as the optimal substrate formula for the container nursery of Camellia oleifera. [Conclusion] This study screened the optimal substrate formula for the container nursery of Camellia oleifera, which provided technical reference for the cultivation of Camellia oleifera container seedlings.[目的]研究油茶容器育苗的最佳基质配方。[方法]在油茶芽苗砧嫁接容器育苗中,将黄心土、松林表土、食用菌残料、泥炭、粪土按不同体积比混合制成5种基质配方,以园土为对照,采用随机区组试验设计,通过方差分析、多重比较,研究各基质对一年生油茶容器苗木生长的影响,从而筛选出最佳基质配方。[结果]不同基质对油茶容器苗的苗木移栽存活率、苗高、地径粗度,高径比、侧根长度影响存在显著性差异。以黄心土40%+松林表土15%+食用菌残料20%+泥炭20%+粪土5%为配方的基质培育的油茶幼苗,各项生长指标均优于对照及其余基质配方,因此可将其作为油茶容器育苗的基质用于推广。[结论]该试验筛选出了油茶容器育苗的最优基质配方,为油茶的容器苗培育提供了技术参考。
