摘要：

为探明氮磷钾配比对陕西商洛地区华中五味子甲素含量的影响，给该地区华中五味子种植过程中合理使用肥料提供科学的理论依据。试验采用三因素四水平正交试验设计，研究氮、磷、钾配比对华中五味子甲素的影响。结果表明：不同氮磷钾配比对华中五味子甲素含量影响差异显著（P<0.05），各营养元素对五味子甲素影响依次为K>N>P，试验区条件下保证最佳华中五味子有效成分的施肥量以氮、钾元素配合施用效果好，果实中五味子甲素含量高，最佳肥料用量是氮肥12.0 g/株、磷肥0 g/株、钾肥8.0 g/株。

Abstract:

In order to clarify the ratio of N, P, K content influence on deoxyschizandrin in Schisandra sphenanthera in Shangluo Shaanxi Province, and provide scientific theory for the reasonable application of fertilizer in Schisandra sphenanthera production. Three factors and four levels of orthogonal design were used to detect the different ratios of N, P, K effects on the content of deoxyschizandrin. The results showed that there was significant difference between N, P, K content (P<0.05) affects on the content of deoxyschizandrin. And the importance of the elements order was K>N>P. In this experiment condition, the best fertilization effect was N and K combining which could ensure content of deoxyschizandrin was highest in the Schisandra sphenanthera fruit. The best fertilizer content was N 12.0 g, P 0 g and K 8.0 g per plant.
