香蜂花、牛至和熏衣草冬季扦插育苗技术研究

以香蜂花、牛至和熏衣草为材料,研究了香草种类、植物生长调节剂、扦插基质和插条节段对香草植物扦插成苗的影响。结果表明,在冬季扦插香草植物,种类是影响其扦插生根成苗的主要因素,3种香草植物都易扦插成苗,其中牛至扦插成苗效果最好。蛭石、珍珠岩及二者混合的基质均利于3种香草植物插条生根成苗,其中以蛭石基质更有利于插条不定根生长。茎段和梢段都可用于该3种香草植物冬季的扦插育苗,但梢段插条的生根质量好于茎段。植物生长调节剂对3种香草植物扦插生根的促进作用不明显。生产中冬季可直接将香蜂花的插条用清水浸泡2 h后进行扦插育苗。

Studies on Cutting Propagation of Melissa officinalis L,Origanum vulgare L and Lavandula angustifolia in Winter

Effects of the species of fragrant plants,plant growth regulators,segments and matrices on cutting propagation of Melissa officinalis L,Origanum vulgare L and Lavandula angustifolia were studied.The results showed that the cuttings of these three species could root easily in winter.The rooting ability of Origanum vulgare L cuttings was the best among the three fragrant plants,with the highest rooting rate and the most rootlets.Vermiculite,pearlite or the mixture of the both was all beneficial to the rooting of the cuttings of these fragrant plants,but vermiculite was the best.Both of the stem segments and the tip segments could be used for propagation,while tip segments performed better than the stem segments in rooting.Plant growth regulators had no significant effects on the rooting of the cuttings of Melissa officinalisL,Origanum vulgare L and Lavandula angustifolia.The cuttings dipped in water for 2 h of Melissa officinalis L could be directly used for propagation in winter.
