摘要
对2 a生油橄榄扦插苗枝条进行短穗无纺袋扦插技术研究。结果表明,3-5 cm长的油橄榄插穗扦插50 d生根率可高达99.0%,对照生根率为87.4%;IBA、根旺、蔗糖3种因素对油橄榄扦插生根影响作用最大的为IBA,低浓度复合生根剂处理扦插生根效果较好,不定根数可达10条左右。认为油橄榄扦插过程中,适当的激素处理可以提高生根率,但扦插环境因子在扦插生根过程中起主导作用。采用无纺袋扦插油橄榄可以明显缩短育苗周期,从而提高育苗经济效益。
Research on short spike cottage technology for two-year-old Olea europaea seedlings in nonwoven bag matrix has been conducted. The results showed that： the rooting rate of 50 d cutting with 3 - 5cm long was up to 99. 0%,control rooting rate was only 87. 4%; Among three kinds of factors,IBA,Genwang,Sucrose,the influence of IBA on rooting rate was significant. The low concentration compound rooting powder had better effects on rooting,adventitious roots was up to 10. In the cuttings process,appropriate hormone treatment could improve the rooting rate,but cutting environmental factors played a leading role in the rooting process; the technology of short spike cottage in nonwoven bag matrix can significantly shorten the breeding cycle,thereby improve nursery economic efficiency.
