Five Camellia oleifera Abel seedling substrates were prepared using the conventional formula, but with the peat substituted by the composts of Camellia oleifera shell, pine chips, palm fiber residues, chicken manure, and sheep manure. The physical and chemical properties of the prepared substrates before and after seedling cultivation were determined and their effects on the growth of Camellia oleifera seedling were analyzed. It was found that the survival rates of the one-year-old seedlings produced from stem cuttings on all substrates at 6 months were greater than 97.5%. As compared with the conventional substrate, the substrates formulated with the composts were able to promote the seedling growth based upon height, ground diameter, root length and root volume measurement. The substrate prepared with the compost of Camellia oleifera shell+ palm fiber residue+ chicken manure (A3), vermiculite and perlite (6:3:1) was the most optimal, which gave 100% seedling survival rate, the greatest seedling height, and the largest ground diameter. In particular, the ground diameters and 26.67% of the seedling heights reached the grade 1 standard for two-year-old seedlings.
采用常规配方，用茶果壳、松针、棕榈纤维渣、鸡粪、羊粪等发酵腐熟物替代泥炭，制备了 5 种油茶实生苗基质，并对育苗前后制备的基质的理化性质及其对油茶实生苗生长的影响进行了分析。结果表明，6 个月时，各基质上扦插一年生苗的成活率均大于 97.5%。与常规基质相比，以茶果壳发酵腐熟物+棕榈纤维渣+鸡粪（A3）、珍珠岩和蛭石（6：3：1）为原料的基质配方更有利于苗高、地径、根长和根体积的生长。其中，以茶果壳发酵腐熟物+棕榈纤维渣+鸡粪（A3）、珍珠岩和蛭石（6：3：1）为原料的基质配方最优，成活率达 100%，苗高最大，地径最大，特别是地径和苗高分别有 26.67%达到二年生苗一级标准。
