摘  要：
为了推广二色胡枝子的优良无性系,对其扦插繁殖育苗技术进行了研究。结果表明:嫩枝扦插是二色胡枝子无性繁殖的主要方式。春末夏初选择当年生枝条的稍部作为插穗,100 mg.L-1NAA处理插穗2 h,扦插过程在自动间歇喷雾条件下进行,二色胡枝子嫩枝扦插成活率可达87%以上。二色胡枝子硬枝扦插较为困难,清水处理的插穗成活率为0,采用NAA 200 mg.L-1处理插穗,成活率达到40%。

摘  要：
In order to extend the excellent clones of Lespedeza bicolor,the cuttage seedling-raising techniques were studied.The results showed that the shoot cutting was one of the rapid propagation techniques suitable to L.bicolor.The tops of the current shoots collected in the late spring or early summer were used as cuttings,which were treated by NAA 100 mg·L-1 for 2 hours.The operation was conducted under the conditions of half sunillumination and automatic intermittent spraying.The survival rate was over 87%.Hard wood cuttings were not suitable for L.bicolor when the cuttins were treated by water,manifested by the survival rate of 0,however,40% of the survival rate could be reached when the cuttings were treated by 200 mg·L-1 NAA.
