摘　　要：为促进天山蓝刺头种子的播种育苗及园林应用,以天山蓝刺头为研究对象,设置不同浸种时间、浸种温度、土壤含水量、播种深度和育苗基质类型探究种子的萌发出苗特性,根据萌发率、萌发势分析最适萌发出苗条件。结果表明,随着浸种时间的延长,天山蓝刺头种子萌发率和发芽势逐渐升高,浸种36 h时出苗率最高,为81.70%;随着浸种温度的升高,萌发率和发芽势逐渐降低,以室温(25℃)处理萌发率和发芽势最高;土壤含水量为10%、沙∶草炭土∶壤土配比为1∶3∶6的基质、播种深度1 cm时,天山蓝刺头种子平均出苗率最高,且出苗最为整齐。In order to promote the sowing and seedling raising and garden application of Echinops tianschanica seeds,E.tianschanica was taken as the research object,and different soaking time,soaking temperature,soil water content,sowing depth and seedling substrate types were set to explore the germination and seedling characteristics of seeds.According to the germination rate and germination potential,the optimum germination and seedling conditions were analyzed.The results showed that with the prolongation of soaking time,the germination rate and germination potential of the seeds increased gradually,and the germination rate was the highest at 36 h,which was 81.70%.With the increase of soaking temperature,the germination rate and germination potential decreased gradually,and the germination rate and germination potential were the highest at room temperature(25℃).When the soil moisture content was 10%,the ratio of sand∶peat soil∶loam was 1∶3∶6,and the sowing depth was 1 cm,the average seedling emergence rate of the seeds was the highest and the emergence was the most neat.
