摘　　要：滇丁香是一种具有较高开发价值的园林观赏树种,利用植物非试管智能化快繁技术进行其扦插苗的规模化快繁,具有生根快、生根率高、移栽成活率好的优势。试验结果证明,滇丁香扩繁最佳的扦插方法是采用其半木质化枝条作为插条,用200 mg/kg的ABT2处理2 h后扦插;其次是用200 mg/kg的NAA或国光生根处理2 h后扦插。在规模化生产中,采用国光生根2 000 mg/kg快速沾根2~5 m in的方法,也可达到生根率90%左右的效果;同时电磁场处理苗床具有杀菌及提高生根率的作用。用非试管扦插快繁方法将未生根植株进行回插,1个月后仍可获得90%以上的生根效果,该特点与其他树种扦插苗的表现显著不同,有利于提高滇丁香扦插苗的生产效率。The tree of Luculia intermedia is high-valued in garden horticulture.A fast intelligent Non-tube seedling cultivation may have the privileges of fostering rooting,higher rooting rate and higher surviving rate after transplanting.From the experiment we showed that best way to the non-tube seedling cultivation was by using half-lignified shoots as cuttage,immensed in 200 mg/kg ABT2 solution for 2 h;the second way was that the same shoots treated with 200mg/kg NAA or Guoguanshenggen solution for 2 h.and for the large-scale production,it could be reached up to 90% rooting rate shortly immersed with 2 000 mg/kg Guoguangshenggen.Meanwhile,treating these shoots with electronic magnetized bed then with non-tube cuttage also reached above 90 % rooting rate in 1 month.The technique is favored in increment of the efficiency of Luculia intermedia production.
