摘　　要：[目的]寻找适合金沙江干热河谷区的辣木种子育苗方法。[方法]比较不同杀虫药剂、种子浸泡温度和基质对辣木出苗率和幼苗的生长情况。[结果]100 mg/L高锰酸钾、1%多菌灵和1%托布津能提高辣木出苗率,对幼苗生长无影响;高温浸泡种子会降低种子出苗率;腐殖土能显著提高提出苗率和幼苗生长状况。[结论]在金沙江干热河谷区田间育苗时,通过种子消毒、常温(20~40℃)浸泡种子和田间施肥都能提高辣木出苗率和幼苗生长程度。[Objective] To find the most suitable method of seedling raising of Moringa oleifera in Jinsha River dry-hot valleys.[Method]Different insecticides and seed soaking temperature and substrate on the growth of seed germination and seedling of Moringa oleifera were compared.[Result]100 mg/L potassium permanganate,1% carbendazim and 1% topsin can improve emergence rate and no influence on seedling growth.High temperature soaking seeds will reduce the seed germination rate,humus soil can improve the germination rate and seedling growth significantly.[Conclusion] Field seedling in Jinsha River dry-hot valleys area,through seed disinfection,soaking seeds at normal temperature（20-40 ℃） and field fertilization can improve moringa germination rate and seedling growth of Moringa oleifera.
