摘　　要：以3种不同饲用苎麻(Boehmeria nivea L.)为研究对象,研究3个不同饲用苎麻品种叶片、茎中微量元素(Cu、Mn、Zn)含量变化规律,并分析了饲用苎麻叶片与茎中微量元素含量的相关性。结果表明,不同品种饲用苎麻叶片和茎中的Cu、Mn、Zn含量变化规律表现不一致,每种饲用苎麻叶片中Cu、Mn、Zn含量均大于茎中的含量,不同饲用苎麻品种叶片和茎中Cu、Mn、Zn含量各不同,但其顺序均为Mn>Zn>Cu,苎麻茎中的Mn与叶片中Mn元素呈显著正相关(P<0.05)。This study used three different feeding ramie(Boehmeria nivea L.) as the research object. The dynamic changes of trace elements(Cu、Mn、Zn) in leaves and stems of 3 kinds of feeding ramie were studied and correlation between the content of trace elements in leaves and stems of feeding ramie was analyzed. The results showed that the dynamic changes of Cu,Mn and Zn contents in leaves and stems of 3 kinds of feeding ramie were inconsistent. The contents of Cu, Mn and Zn in different varieties of feeding ramie were higher than those in stems. The order of Cu, Mn and Zn in different varieties of feeding ramie leaves and stems was: Mn >Zn >Cu. There was a significant positive correlation between Mn in the stem of ramie and Mn in leaves(P<0.05).
