不同氮磷钾配比对商洛华中五味子有效成分五味子乙素含量的影响

摘要

By the orthogonal design with three factors and four levels, the field fertilizer efficiency test was carried out in high dam Schisandra sphenanthera base in Shanyang in 2009. The results indicated that the influence of different ratios of nitrogen, phosphorus and potassium on the content of active constituent schisandrin in Schisandra sphenanthera appeared obvious difference, and the influence of different nutrient elements on schisandrin content showed the following order; K >N > P. The combined utilization of N and K fertilizer got the highest schisandrin content in the test site, and the optimum application rate of N and K,0 was 240 kg/hm2 and 160 kg/hm2 respectively.%采用三因素四水平正交试验设计,于2009年在山阳高坝华中五味子基地进行了肥效田间试验.结果表明:不同氮磷钾配比对华中五味子乙素含量影响差异显著；各营养元素对五味子乙素含量影响依次为K＞N＞P；在本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,果实中五味子乙素含量高,最佳肥料用量:N用量240 kg/hm2,K2O用量160 kg/hm2.
