对石灰岩植物桂林唇柱苣苔采用不同扦插基质、不同时间和不同叶片大小进行扦插繁殖试验,结果表明:4种扦插基质中,石灰岩土与珍珠岩+细园土最好,平均成苗率＞95 %,可形成2～3个不定芽,叶多为6片,叶长4～5 cm,火烧土最差;3种扦插时间中,3月扦插的平均成苗率最高,为(98.67±2.31) %,叶长(4.31±0.09) cm;1.0 cm×0.5 cm ≤繁殖叶片≤ 1.5 cm×1.5 cm时,平置法比直插法效果好,平置的平均成苗率为(88.67±8.08) %,比直插高20 %～30 %,繁殖叶片大小为2.0 cm×2.0 cm时,直插的效果比平置略好,平均成苗率为(94.00±5.29) %,比平置高10 %以上.

A cutting experiment about a limestone species Chirita gueilinensis was conducted with 3 different treatments:different cutting medium,different cutting time,and different cutting leaf size. The results showed that the best cutting medium was limestone soil and perlite＋fine park soil among the four substrates. By this cutting medium treatment,the average seedling rate exceeded 95 %,and the seedling with 2-3 adventitious buds,and 6 average leaves. The poorest cutting medium was ash soil. Among the 3　cutting time treatment,the optimum month is March. The average seedling rate was up to (98.67±2.31) % which cutting in this month,and the leaf length of the seedling reached (4.31±0.09)cm. By using the cutting leaf size between 1 cm×0.5 cm and 1.5 cm×1.5 cm,the average seedling rate was up to (88.67±8.08) % with placed leaf material horizontal on the medium,which was higher 20 %- 30 % than that vertical on the medium. By using the cutting leaf size 2 cm×2 cm,the seedling rate of placed leaf material vertical on the medium was higher 10 % than that of horizontal placed,which was (94.00±5.29)%.
