【摘要】 采用景宁县外舍雷公藤苗圃1年生枝条,粗3～5 mm,长12～15 cm,每段带节2～3个,以插条下端切口位置为节间任意部位、芽下位置为处理作扦插试验,结果表明,插条下端切口不同位置对雷公藤苗木的成活率有差异,芽下切口扦插的苗木平均成活率(72.4%)显著高于节间任意剪切位置的苗木平均成活率(57.8%);二种处理对苗木地上和地下部分生长影响不是很明显,但芽下切口扦插苗木质量相对较好。更多还原

【Abstract】 Experiment was carried out on effect of different cutting point of Tripterygium wilfordii on survival rate and quality of seedling with 1-year branch of 3-5mm of diameter and 12-15cm long.The result showed that the survival rate of seedling cut below bud was 72.4%,evident higher than that of cut between internodes.The treatments had no significant effect on growth of seedling.Seedling cut below bud had better quality.更多还原
