摘要
贵州野生苦丁茶(LigustrumrobustumBl.)人工播种后发芽率仅5%左右,采用150mg/kg赤霉素液浸种24h,可有效解除抑制,提高发芽率至60%以上。苦丁茶种子萌发过程需要适当的光照,育苗应浅播浅盖。扦插繁殖:1~2年生枝条和当年生绿枝扦插成活率为37%左右,老枝成活率仅18%;应用吲哚丁酸、生根粉等处理插条可提高成活率,对老枝插条处理效果更显著。
Artifical planting of wild Kudingcha (Ligustrum robustum Bl.) just begins.Only about 5% of its seeds can germinate after sowing.Before sowing the seeds should be soaked in 150 ppm gibberellic acid solution for 24 h. Sowed seeds are relieved in the retardation and its sprouting rate over 60%.Because sprouting of seeds reguire a certain light,the seeds should be sowed shallowly.The surviving rate of cutting roots with one or two years old twig are about 37%,it is only about 18% to the old branches.Cutting branches soaked in indole butyric acid or rooting powder etc.solution,the surviving rate could be increased,especially to the old branches.
