【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。更多还原

【Abstract】 Objective: To study the effects of seedling and fertilizer on yield and quality of cultivated Changium smyrnioides and build 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.更多还原
