【摘要】 通过火焰原子吸收光谱法对扶桑枝叶花器官的K、Ca、Mg、Na、Fe、Mn、Zn、Cu、Cr、Ni的含量进行测定分析,为指导扶桑的种植栽培及综合开发利用提供科学数据。结果表明,10种矿质元素在各部位中的含量(平均值)高低顺序为Ca>K>Na>Mg,Fe>Mn>Zn>Cu>Cr>Ni。同一元素在扶桑各部位之间含量存在一定的差异。所测扶桑品种各部位中的Ca、Na、Fe、Mn、Zn、Cu的含量多数落在一般植物体的正常含量范围内,与一般植物相比,扶桑Mg、K含量偏低,Cr含量偏高,部分部位未能检出Ni元素。更多还原

【Abstract】 In order to provide the basic data for production and cultivation of Hibiscus rosa-sinensis Linn. var.rubro-plenus and its comprehensive development and utilization, the contents of K, Ca, Na, Mg, Fe, Mn, Cu,Zn, Cr, Ni were measured by the method of flame atomic absorption spectrometry(FAAS) in branches andleaves and flowers of Hibiscus rosa- sinensis Linn. var. rubro- plenus. The results showed that 10 elementsexisted in all the organs of the Hibiscus rosa-sinensis Linn. var. rubro-plenus. The order of the average contentwas: Ca>K>Na>Mg, Fe>Mn>Zn>Cu>Cr>Ni. The content of the element was different among 17 parts of Hibiscus rosa- sinensis Linn. var. rubro- plenus. The average content of Ca, Na, Fe, Mn, Zn and Cu in the Hibiscus rosa-sinensis Linn. var. rubro-plenus belonged to the normal content level of the elements in plants.The contents of Mg and K in the Hibiscus rosa-sinensis Linn. var. rubro-plenus. were relatively lower than thatin the general plants, but the content of the Cr was relatively higher than that in the general plants. In addition,some parts of the plant did not include Ni element.更多还原
