目的：研究肥料种类和用量对款冬生物量分配、产量和品质的影响。方法：随机区组试验设计,取样测定生物量分配,田间统计产量；分别用HPLC法测定款冬芦丁含量和UV法测定款冬总黄酮含量。结果：在一定肥料施用范围内,肥料种类和用量能明显提高款冬的产量和芦丁、总黄酮含量,并增加生物量向经济器官分配。结论：磷、钾肥能提高款冬花蕾的数量,生产上应适当控制氮肥的用量；氮、磷、钾肥及有机肥在一定施用范围内,能增加款冬花产量和提高款冬花的品质。

The paper discusses the effect of fertilization on yield,quality and biomass distribution of Tussilago farfara,in the context of fertilizer type and application quantity.The following are among the basic methods and processes used in the study:survey of biomass distribution,yield statistics collection,and HPLC and UV for measuring rutin content and total flavones in T.farfara.It is found that both fertilizer type and application quantity are of a noticeable effect on biomass distribution,yield,rutin content,and total flavones.Authors conclude that phosphate and potash fertilizer can noticea- bly increase the number of T.farfara buds,with a controlled application of nitrogen.Nitrogen,phosphate,and potash fertilizer and organic manure can,in a reasonable range,increase both the yield and quality of T.farfara.
