摘　　要：在新能源不断开发与利用的时代背景下,毛梾作为生物质能源的重要生产原料之一,其培育质量与繁殖效率的综合提升,是未来新能源市场结构优化以及毛梾苗木产业经济效益提升的关键环节。但现阶段我国毛梾生产过程中存在繁殖慢、良种少、幼苗成活率低等主要问题,文章深入分析了毛梾的生根机理,并对其扦插育苗进行了研究。结果表明,毛梾在4000×10^(-6)左右的吲哚乙酸,2000×10^(-6)左右的Ca(NO_(3))_(2),以及3000×10^(-6)左右的维生素B1等物质的影响下,生根发育效果好,同时,选择愈合组织生根类型进行生根育苗,能够有效保证生根率及生根效果,具有较高的育苗繁殖技术价值。本研究可为毛梾硬枝扦插育苗提供一定的技术参考和理论支持。In the context of the continuous development and utilization of new energy,as one of the important raw materials for the production of biomass energy,the comprehensive improvement of its cultivation quality and reproductive efficiency is a key link for the optimization of the future new energy market structure and the improvement of economic benefits of Swida walteri seedling in‐dustry.However,there are some problems in the production of Swida walteri at present,such as slow propagation,few good varieties and low survival rate of seedlings.The rooting mechanism of Swida walteri was deeply analyzed and its cuttage breeding was stud‐ied in this paper.The results showed that Swida walteri had good rooting and development effect under the influence of 4000×10^(-6)indole acetic acid,2000×10^(-6)Ca(NO_(3))_(2),and 3000×10^(-6)vitamin B1.Meanwhile,selecting the rooting type of healing tissue for root‐ing seedlings could effectively ensure the rooting rate and rooting effect.It has high technical value of seedling breeding.This study can provide some technical reference and theoretical support for the cuttage breeding of Swida walteri.
