摘要: 研究氮、磷、钾配施对广金钱草药材生长及夏佛塔苷含量的影响,为广金钱草的合理施肥及规范化种植提供依据。试验设计采用大田随机区组法,夏佛塔苷含量测定采用HPLC法。除A03、A06、A12、A13处理外,其他各施肥处理夏佛塔苷含量均达到2010版《中国药典》不低于0.13%的最低标准。其中,施氮量12 g/m2,氮:磷:钾=3:2:2(A07)、施氮量18 g/m2,氮:磷:钾=3:1:1(A13)及施氮量18 g/m2,氮:磷:钾=3:2:1(A14)处理的生物量积累和夏佛塔苷单株产量位于前3位。通过相关分析结果表明,夏佛塔苷含量的积累与地上部分和地下部分的生物量呈极显著正相关关系。通过对施肥量、产量、夏佛塔苷含量的综合比较发现,以施氮量12 g/m2,氮:磷:钾=3:2:2(A07)处理最为经济有效,氮、磷、钾合理配施能够提高广金钱草药材的产量和质量。

Abstract: The aims were to study the effects of nitrogen (N), phosphorous (P) and potassium (K) fertilizers on the growth and schaftoside content of D. styracifolium, and provide scientific basis for its rational fertilization and standardized cultivation. Randomized block design in yield was used and content of schaftoside was determined by HPLC. The content of schaftoside in different groups came up to the standards in the Chinese pharmacopoeia except for A03, A06, A12, A13 groups. By comparing biomass accumulation and schaftoside content of single plant among the different treatment groups, the top three groups were as follows: N=12 g/m2, N:P:K=3:2:2 (A07), N=18 g/m2, N:P:K=3:1:1 (A13), and N=18 g/m2, N:P:K=3:2:1 (A14). There was a significant positive correlation between the schaftoside content and plant biomass. In consideration of fertilizer amount, yield and schaftoside content, the treatment mode of A07 (N=12 g/m2, N:P:K=3:2:2) was the most economic. The reasonably fertilizing in complex treatment of N, P, K could increase the yield and quality of D. styracifolium.
