摘　　要：以炭化树皮、锯末、炭化锯末、杉表土为材料,进行了12个处理的柚木组培瓶苗移植育苗基质试验,结果显示:对成活率有促进作用的基质有锯末和杉表土;对保存率有促进作用的的基质只有锯末;炭化树皮、杉表土对苗高、径有促进作用;50%炭化树皮+50%杉表土和80%炭化树皮+10%炭化锯末+10%锯末处理基质移植成活率、保存率分别大于95.1%,95.0%,一年生苗平均苗高、苗地径分别在33.4 cm,0.68 cm以上。We carried out some experiments on different nursery substrates, e. g. carbonized bark, sawdust, carbonized sawdust, topsoil of Cunninghamia lanceolata, with 12 different treatments during transplanted the tissue culture seedlings of Tectona grandis. Results shows that （ 1 ） sawdust and topsoil of Cunninghamia lanceolata can promote survival rate of the seedlings; （2） sawdust is the only substrate that promotes the preserving rate ; （ 3 ） carbonized bark and topsoil of Cunninghamia lanceolata can accelerate the growth of seedling height and diameter; （4） the survival rate and the preserving rate of seedling in the treatment of 50% carbonized bark ＋ 50% topsoil of Cunninghamia lanceolata and the treatment of 80% carbonized bark ＋ 10% carbonized sawdust ＋ 10% sawdust are greater than 95.1% and 95.0%, and the average height and average diameter of one-year-seedlings in the above treatments reach 33.4 era,0.68 cm respectively.
