摘　　要：目的研究氮磷钾用量、配比以及施用时期对丹参产量和质量的影响,优化丹参高产施肥模式。方法以蒙阴丹参农家种为材料,采用四因素三水平正交试验设计,安排田间小区试验,收获期测定各处理丹参产量和有效成分(丹参酮ⅡA和丹酚酸B)含量。结果移栽丹参种苗之前每公顷施用底肥N、P2O5和K2O分别为225kg、150kg和150kg,可使丹参产量达到7000kg/hm2以上,有效成分符合药典规定标准。结论移栽丹参种苗前每公顷施用225kg N、150kg P2O5、150kg K2O为适宜施肥配比、施肥时期和施肥量。Objective To optimize the fertilizer application model for higher yield of Salviae miltiorrhiza, by researching the effect of yield and quality on the application quantity, ratio and stage of nitrogen phosphorus potassium. Methods A plot experiment by orthogonal design was conducted with local variety of Salviae miltiorrhiza. The yield of Salviae miltiorrhiza was estimated and content of Tanshinone II A and Salvianolic acid B was determined in harvest stage. Results From the view of yield and content, the optimization of fertilizer application model of Salviae miltiorrhiza is to apply N 225kg, P205 150kg, K20 150kg per hectare as base manure, then the yield can reach 7000kg/hm2, and the effective components conform to the standard of the pharmacopoeia.
