- 摘要:
- 以乡土植物桃金娘为试材,采用正交实验方法,研究了不同浓度IAA、IBA、NAA及扦插基质细沙、红壤、轻基质对桃金娘扦插成活及生根的影响。结果表明:生根剂、生根剂浓度及扦插基质对桃金娘扦插成活及根长有显著影响,对生根数量影响差异不明显,采用IBA处理平均成活率达77.33%,300 mg?L-1浓度的生根剂平均成活率达69.67%,红壤土平均成活率达79.33%,4号组合IBA+300 mg?L-1+红壤土扦插成活率为84%,明显高于其它组合(P<0.05),达到了提高扦插成活的目的,值得应用推广。同时,适当的遮阴、消毒和保湿处理有助于促进扦插成活和生根。
- Abstract:
- Using the orthogonal experimental design method, the effects of different concentrations of IAA, IBA, NAA, as well as cutting medium such as fine sand, red soil and light matrix, on the cutting survival and rooting of myrtle were studied with the native plant myrtle as material. The results showed that rooting agent and its concentration and cutting medium had significant effects on the survival and root length of myrtle, but the difference in effects on rooting number was not obvious. The average survival rate was 77.3% after IBA treatment, up to 69.67% for the concentration of 300 mg?L-1, and 79.33% in red soil, and the cutting survival rate of combination No.4 of IBA 300 mg?L-1+red soil in experimental group was 84%, which was significantly higher than other combinations (P<0.05). In order to improve the cutting survial, this is worth applying for promotion. At the same time, proper shading, disinfection and moisturizing treatment help to promote cutting survival and rooting.
