摘  要:通过分析闽楠、木荷、山桐子、榉树容器苗的苗高、地径及高径比等指标,研究了25种基质对闽楠、木荷、山桐子、榉树容器苗生长的影响的结果表明,不同树种的最适基质成分不同;结合基质成本,筛选出4种树种的通用基质有2种:即泥炭(0.6)+蘑菇泥(0.4)或稻壳(0.4);筛选出适合3个树种的通用基质:分别为适合木荷、山桐子、榉树的2种,即泥炭(0.46)+蘑菇泥(0.27)+稻壳(0.27)和泥炭(0.46)+珍珠岩(0.27)+稻壳(0.27);适合木荷、闽楠、榉树的有1种,即泥炭(0.6)+珍珠岩(0.4);适合闽楠、山桐子、榉树的通用基质3种,即泥炭(0.2)+珍珠岩(0.4)+蘑菇泥(0.4)、泥炭(0.46)+珍珠岩(0.27)+蘑菇泥(0.27)和泥炭(0.2)+珍珠岩(0.27)+蘑菇泥(0.27)+稻壳(0.27)。Contrast tests were conducted on the growth of Phoebe bournei, Schima superba, Idesiapolycarpa, and Zelkova serrata containers. The effects of 25 substrates on the growth of container seedlings ofPhoebe bournei, Schima superba, Idesia polycarpa, and Zelkova serrata were studied by analyzing theseedling height, ground diameter, and height-to-diameter ratio of container seedlings of Phoebe bournei,Schima superba, Idesia polycarpa, and Zelkova serrata. The results showed that the optimum substratecomposition of different tree species was different; combining with the cost of the substrate, there were twocommon substrates for screening out four tree species: namely [peat (0.6) + mushroom mud (0.4) or rice husk(0.4)]; General substrates suitable for 3 tree species: 2 species suitable for Schima superba, Idesia polycarpa,Zelkova serrata, namely [Peat (0.46) + Mushroom Mulberry (0.27) + Rice Husk (0.27)] and [Peat (0.46)+Pearl Rock (0.27) + rice hull (0.27)]; suitable for Schima superba, Phoebe bournei, Zelkova serrata 3 species[ie, peat (0.6) + perlite (0.4)]; suitable for Phoebe bournei, Idesia polycarpa, Zelkova serrata Three commonsubstrates, namely [Peat (0.2) + Perlite (0.4) + Mushroom (0.4)], [Peat (0.46) + Perlite (0.27) + Mushroom(0.27)] and [Peat (0.2) + Perlite (0.27) + mushroom mud (0.27) + rice husk (0.27)].
