摘　　要：辣木营养丰富,市场潜力大,种植面积在不断扩大。研究辣木扦插繁殖技术能大幅度提高辣木的育苗效率。通过田间观测,主要研究辣木扦插环境、抑芽剂控梢促根效果及辣木扦插生根特点等。结果表明,辣木在扦插过程中受白蚁的危害较大,需通过隔离的方式才能有效控制;辣木的成枝力很强,插穗插后约一周就能抽芽长梢,涂抹200倍的抑芽剂能明显抑制枝梢的生长,促进辣木插穗生根;通过观察发现,辣木的扦插生根为皮部生根类型。Moringa ol eifera has considerable potential for market development given its high nutrient content.Considering the continuous expansion of planting area under M.oleifera,cutting could improve the propagation efficiency of M.oleifera for seedling raising.The optimal cutting environment,the effect of bud suppressants on the suppression of shoot growth and facilitation of rooting,and the characteristics of rooting were observed in the field.Results showed that the cuttings were severely infested by termites.Cuttings must be isolated to avoid termite infestation and damage.The cuttings of M.oleifera sprouted after cutting about a week.Application of bud suppressants diluted at a ratio of 1∶200 clearly controlled the shoot growth but promoted the rooting of cuttings.In addition the cuttings of M.oleifera were observed to root from the bark.
