摘要:
以野含笑为试材，采用4种不同扦插基质和3种不同浓度K-IBA激素对野含笑进行了嫩枝扦插繁殖试验，研究了不同基质及激素浓度对野含笑扦插生根的影响，以筛选出提高野含笑扦插育苗的方法。结果表明：扦插前采用8 000 mg/L的K-IBA激素处理嫩枝，并在泥炭土∶珍珠岩=1∶3混合的基质中进行培育，生根率最高（71.88%），且基质对野含笑扦插生根率的影响处于主导地位，激素浓度对生根数和主根总长度影响更重要。
Abstract:
Taking Michelia skinneriana as test material,using 4 different cuttage substrates and 3 different concentrations of K-IBA hormone reproduce shoot cutting experiment was conducted on Michelia skinneriana, the effect of different substrates and hormone concentration on Michelia skinneriana cuttage rooting were studied,in order to screen out the best methods of improving the Michelia skinneriana cuttage seedling.The results showed that using 8 000 mg/L of K-IBA hormone treatment twig,then cultivated it in the substrates including peat soil∶perlite=1∶3,with this method the rate of rooting was the highest (71.88%). Substrate had a dominant position for rooting of the Michelia skinneriana,the hormone concentrations were more important for the number of rooting and the total length of taproot.
