摘　　要： 采用全光照自动间歇喷雾装置,河沙做基质,用不同激素(ABT1、NAA、IBA和GGR)、ABT1不同浓度和处理时间、不同插穗长度、不同采穗母株年龄、不同插穗类型(嫩枝带硬枝和嫩枝)的欧洲云杉扦插生根试验,清水处理插穗做对照(CK),试验数据经spss12.0分析。结果表明,不同激素处理的插穗生根率差异显著,生根率ABT1>GGR>IBA>NAA。而IBA处理的插穗生根数,根系总长和根系效果指数最高,根系发达。ABT1不同浓度和处理时间以100 mg.kg-1和200 mg.kg-1浸泡30 min和2 h的插穗生根率最高。50 mg.kg-1浸泡1 h的插穗生根数、根系总长、根系效果指数最高。嫩枝带硬枝的生根数、根系总长和根系效果指数>嫩枝。>15 cm的插穗生根数、根系总长、根系效果指数最高。采自23 a生母株的插穗生根率为0.0%。 Using river sand as medium, the cutting experiment of Picea abies was carried out under the full sunlight and automatic intermittent spraying. The results showed that cuttings treated with different hormones generated significantly different rooting rates, and in the order of ABT1 〉 GGR〉 IBA〉 NAA. However, the number of roots generated, total rooting length and the root effect index of the cuttings treated with IBA were better than those treated by other hormones. The rooting rates were the highest when the cuttings were treated by ABT1 with the concentrations of 100 mg · kg^-1 for 30 min and 200 mg · kg^-1 for 2 h. The number of roots generated, total rooting length, and root effect index were the highest when the cuttings were treated by ABT1 with the concentrations of 50 mg· kg^-1 for 1 h. The number of roots generated, total root length and the root effect index of shoots with hardwood outnumbered shoots, and cuttings length at 〉15 cm were the best. The rooting rates of the cuttings from 23 a mother trees were 0.0%.
