摘　　要：目的:研究不同施肥处理对何首乌药材单株鲜质量及有效成分的影响,为何首乌合理施肥提供参考。方法:以2年生何首乌为实验材料,采用“3414”试验设计,测定不同施肥处理下何首乌单株鲜质量、二苯乙烯苷类、游离蒽醌类、结合蒽醌类成分含量。结果:施肥组何首乌的单株鲜质量明显高于不施肥组,对各成分含量的影响较小,且不同施肥处理的何首乌单株鲜质量及各成分含量间差异有统计学意义(P<0.01),单株鲜质量、结合蒽醌类、游离蒽醌类含量主要受钾肥影响,二苯乙烯苷类含量主要受氮肥影响。结论:施肥处理在一定程度上可以提高何首乌单株鲜质量和有效成分的含量,当施肥量为氮肥13.8 g·m^(-2)、磷肥6.3 g·m^(-2)、钾肥13.5 g·m^(-2)时何首乌综合品质最佳,此时单株鲜质量为140.67 g。Objective:To study the effects of different fertilization treatments on the fresh weight per plant and the effective components of Polygoni Multiflori Radix,provides a theoretical basis for rational fertilization of Polygonum multiflorum.Methods:The fresh weight,contents of stilbene glycosides,free anthraquinones and combined anthraquinones of two years old P.multiflorum under different fertilization treatments were determined by using″3414″experimental design.Results:The fresh weight per plant in the fertilization group were significantly higher than those in the non fertilization group,and had little effect on the contents of each component.There were significant differences in the fresh weight per plant and the content of each component among different fertilization treatments(P<0.01).The fresh weight per plant,combined anthraquinones and free anthraquinones were mainly affected by potash fertilizer,the content of stilbene glycosides were mainly affected by nitrogen fertilizer.Conclusion:To a certain extent,fertilization could improve the fresh weight and the content of effective components of P.multiflorum.The best quality and fresh weight of P.multiflorum per plant could be obtained with the fertilization amount of N 13.8 g·m^(-2),P 6.3 g·m^(-2) and K 13.5 g·m^(-2),and the fresh weight of P.multiflorum per plant was 140.67 g.
