摘　　要：目的:以张家口崇礼县野生金莲花Trollius chinensis Bge.种子为材料,筛选其萌发条件及育苗条件,以期为建立张家口市金莲花育苗栽培技术体系提供理论依据和实践技术。方法:通过温室对比试验,定期观察并进行数据的采集和分析。结果:金莲花育苗时种子处理最适宜的条件为GA3浓度800 mg/m L在4℃条件下冷浸4 d后,放置于人工气候箱内,温度为20℃,光照处理为光照12 h/黑暗12 h,处理4 d,期间用30 g/L PEG 6000溶液喷洒,4 d后播种,基质选用草炭土,出苗率能够达到85%以上。结论:根据温室内幼苗外观特性及大田移栽后幼苗外观特性的观察,幼苗生长健壮,病虫害较少,移栽成活率较高。Objective： To screen the germination and seedling conditions of Trollius chinensis seeds from Chongli county,Zhangjiakou city. To provide the theoretical basis and practical technology for establishing technology system of seedling and cultivation of Trollius chinensis seeds in Zhangjiakou city. Methods： The data were collected and analyzed by the contrast test of greenhouse. Results： The most suitable conditions of Trollius chinensis seedling treatment were as follows,the concentration of GA3 was 800 mg / m L at 4 ℃,and under this condition in infusing for 4 days,and placed in the artificial climate chamber,the temperature was 20 ℃,light treatment for 4 days with 12 h light and 12 h darkness,and sprayed PEG 6000（ 30 g / L）. Trollius chinesis seeds were sowed on the 4th day,peat soil was selected as matrix,and the germination rate reached more than 85%. Conclusion： According to the characteristics of the seedling appearance and the conditions of the seedlings after transplanting,the seedling growth is robust and the survival rate is much higher.
