摘　　要：为了研究不同施肥量和施肥种类对菘蓝(板蓝根和大青叶)产量及有效成分含量的影响,确定最佳的施肥量和施肥种类,进行了氮、磷、钾及有机肥单因素随机区组试验。结果表明:菘蓝产量最大和有效成分含量最高的施肥处理是N、P_2O_5、K_2O用量分别为150kg/hm^2、180kg/hm^2和270kg/hm^2,有机肥为复合菌肥。结论:氮肥对板蓝根产量的影响较为明显,钾肥对大青叶产量的影响较为明显,以豆粕为基质的菌肥更有利于提高板蓝根产量和有效成分含量。The single-factor randomized block test was used to study the effects of different fertilizers with different application amount on yield and active ingredient content of I.indigoticaand determine the optimum fertilizer type and application amount.Results：The maximum yield and highest active ingredient content of I.indigoticaare obtained under the application conditions of 150kg/hm^2 N,180kg/hm^2P2O5270kg/hm^2K2O and compound microbial fertilizer.In conclusion,nitrogen fertilizer has the obvious effect on yield of Radix isatidis but potassium fertilizer has the significant effect on yield of Folium isatidis.The compound microbial fertilizer with bean pulp is more beneficial to increasing yield and active ingredient content of R.isatidis.
