摘　　要：目的：研究种苗质量与施肥对明党参产量和质量影响，为明党参规范化种植提供依据。方法：进行不同等级种苗和施肥的小区栽培试验，研究种苗和施肥对明党参产量和多糖含量的影响。结果：种苗等级对明党参药材产量有显著影响；施肥深度对明党参产量影响差异显著，以10～15cm深度最佳；有机肥和氮肥、磷肥配合施用，明党参多糖含量最高。结论：移栽时种苗以一级和二级种苗最佳；明党参施肥时最好是有机肥和氮肥、磷肥配合施用，施肥深度为10～15cm。Objective： To study the effects of seedling and fertilizer on yield and quality of cultivated Changium smyrnioides and buiM a basis for its GAP. Method： Experiments were conducted to study the effects of seedling quality and different fertilizering measures on yield and quality of cultivated C. smyrnioides. Result： The seedling and fertilizering depth affected the yield of roots obviously. Organic fertilizer combined with nitrogen and phosphorus could increase the amylose content obviously. Conclusion： In cultivation, the seedling （root length 〉5. 0 cm, root diameter 〉0. 3 cm, fresh root weight 〉0. 3 g） is optimal. The ideal combination is nitrogen, phosphorus and organic fertilizer. The suggested fertilizering depth ranged from 10 to 15 cm.
