摘　　要：利用桂林唇柱苣苔(Chirita gueilinensis)、大岩桐(Sinningia speciosa)、吊石苣苔(Lysionotus pauciflorus)、半蒴苣苔(Hemiboea henryi)、口红花(Aeschynanthus acuminatus)、非洲紫罗兰(Saintpaulia ionantha)6种苦苣苔科野生花卉进行泥炭土、珍珠岩、蛭石和黄泥的不同配比栽培试验。对栽培在7种不同基质中的每个植物进行生长性状分析,并测量其株高、冠幅生长量和叶绿素含量。结果表明:半蒴苣苔、吊石苣苔和桂林唇柱苣苔的最佳基质配比为泥炭土∶蛭石=2∶1;非洲紫罗兰的最优基质配比为泥炭土∶珍珠岩∶蛭石=2∶1∶1;大岩桐的最佳基质配比为泥炭土∶蛭石∶黄泥=2∶1∶1;口红花的最佳基质配比为泥炭土∶珍珠岩∶蛭石∶黄泥=2∶1∶1∶1。The cultivation experiments were carried out to test the effects of different proportions of peat soil, perlite, vermiculite, and yellow mud. on 6 species of Gesneriaceae （Chirita gueilinerzsis, Sinningia speciosa, Lysionotus pauciflorus, Hemiboea henryi, Aeschynanthus acuminatus, and Saintpaulia ionantha） The growth traits were investigated for each plant growing in 7 different matrix materials. The height, crown volume growth and chlorophyll content of each plant were measured. The results showed that the best substrate ratio was peat soil：vermiculite=2：l for C. gueilinensis, L. pauciflorus and H. henryi; peat soil ：perlite ：vermiculite=2 ： l ： l for S. ionantha; peat soil：vermiculite：yellow mud=2：l：l for S. speciosa; and peat soil：perlite：vermiculite：yellow mud=2：l：l：l for A. acuminatus.
