摘　　要：米老排（Mytilaria laosensis Lecomte）别名壳菜果、三角枫，属金缕梅科（Hamamelidaceae）常绿阔叶乔木，原生分布于我国云南和两广，同时越南和老挝亦见。作为重要的饲料资源和油脂资源，米老排也是防火林带及长期的火烧山土壤造林的先锋树种，其木材可制作家具、胶合板、客车车箱、纸浆等，是我国的优良速生用材树种，具有极高的生态和经济价值。近年来，作为优良的乡土树种，米老排在生产上不断得到推广应用。9 mycorrhizal fungi, including 4 ectomycorrhizal fungi （ECMF） and 5 arbuscular mycorrhizal fungi （AMF） , were used to explore their effect on seedling growth of Mytilaria laosensis. The study shows that M. laosen- s/s is one of the species with both VAM and ECM. Mycorrhizal infection rate of all ECM inoculation methods reached level 3, and that of AMF infection rate was 88% -93%, of which AM91 became the highest. In different periods, different inoculation treatment expressed different effects on seedling growth. At the end of the experiment, the height, ground diameter, underground dry mass and upper ground dry mass of seedling inoculated with PX0801 and 9006 respectively increased by 71% , 45%, 128% , 184% , and 65%, 54% ,150%, 208%, which exhibited the best overall effect. Coinoculated seedlings with AM90036, AM3008 and AM91 had advantages over uninoculated ones in all the tested growth indicators, which suggest to significantly promote the growth of M. laosensis. The results obtained provide reference for mycorrhizal fungi application on M. laosensis.
