旨在指导山杜英的生产栽培,为其园林绿化及其综合开发利用提供基础数据。通过火焰原子吸收光谱法分析山杜英15个部位的K、Ca、Na、Mg、Fe、Mn、Cu、Zn、Cr、Ni金属元素的含量,结果表明,所测10种金属元素在山杜英的各部位均有一定的分布,其含量(平均值)高低顺序表现为:K〉Ca〉Mg〉Na〉Fe〉Mn〉Zn〉Ni〉Cr〉Cu。同一元素在山杜英15个部位中的含量存在不同程度的差异。所测山杜英15个部位中的Ca、Mg、Mn、Zn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,山杜英中Fe、Cr、Ni元素含量相对偏高,K、Na、Cu元素含量相对偏低。
The objective is to guide the production cultivation of Elaeocarpus sylvestris(Lour.) Poir., andprovide the basic data for its landscaping and 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 15 parts of Elaeocarpus sylvestris(Lour.) Poir.. The results showed that 10 elements existed in all theorgans of Elaeocarpus sylvestris(Lour.) Poir.. The order of the average content was: K〉Ca〉Mg〉Na〉Fe〉Mn〉Zn〉Ni〉Cr〉Cu. The contents of the same element were different among 15 parts of Elaeocarpus sylvestris(Lour.) Poir.. The average contents of Ca, Mg, Mn and Zn in 15 parts of the Elaeocarpus sylvestris(Lour.) Poir. belonged to the normal content levels of the elements in normal plants. The contents of Fe, Cr andNi in 15 parts of Elaeocarpus sylvestris(Lour.) Poir. were relatively higher than those in normal plants, but thecontents of the K, Na and Cu were relatively lower than those in normal plants.
