摘　　要：通过连翘扦插育苗试验,探索一套培育连翘优质移栽苗的技术方法,可为连翘扦插苗优质生产提供技术指导和理论依据。采用L9(34)正交试验方法,分别利用1 a生(嫩枝)和2 a生(硬枝)的连翘插穗,研究了植物生长调节剂种类、质量浓度和处理时间对连翘扦插苗成活和生根情况的影响。结果表明:将连翘嫩枝插穗在浓度200 mg/kg的ABT1生根粉溶液中浸泡0.5 h后进行扦插,成活率最高能达到92.1%,且生长良好;将连翘硬枝插穗在浓度200 mg/kg的ABT1生根粉溶液中浸泡2.0 h后进行扦插,成活率最高能达到72.3%。该插穗处理方法可行、高效,且操作简便,连翘嫩枝和硬枝均可用于扦插育苗。由于连翘嫩枝是结果枝组,因此生产上应尽量减少使用嫩枝扦插育苗,推荐在秋季果实采完后截取硬枝科学处理后进行扦插育苗。To explore a set of technical methods for cultivating high-quality transplanting seedlings of Forsythia suspensa through cutting seedling cultivation experiments,can provide technical guidance and theoretical basis for high-quality production of F.suspensa cutting seedlings.Using L9(34)orthogonal experimental method,the effects of plant growth regulators,mass concentration,and treatment time on the survival and rooting of F.suspensa cuttings were studied using 1-year-old(tender branches)and 2-year-old(hard branches)cuttings,respectively.The results showed that the soaking the young branches of F.suspensa in 200 mg/kg ABT1 rooting powder solution for half an hour before cutting,the highest survival rate can reach 92.1%and the cuttings grow well.Soaking the hardwood cuttings of F.suspensa in 200 mg/kg ABT 1 rooting powder solution for 2.0 hours before cutting,and the highest survival rate can reach 72.3%.This cutting treatment method is feasible,efficient,and easy to operate.Both the tender and hard branches of F.suspensa can be used for cutting seedling cultivation.Due to the fact that the tender branches of F.suspensa are a group of fruiting branches,the use of tender branches for seedling cultivation should be minimized in production.It is recommended to cut off the hard branches after harvesting the fruits in autumn and conduct scientific treatment for seedling cultivation.
