【摘要】 小兴安岭改造后森林沼泽是兴安落叶松——泥炭藓沼泽经挖沟排水改造而成．测试分析沼泽植物中有微量元素20余种，对植物生长发育最有影响的元素有锰、锌、硼、钴、铜。它们在植物体内的含量有明显差异。但也有共性，即锰＞锌＞硼＞铜＞钴．植物各器官的主要微量元素含量亦不同，器官中的微量无素含量的时序变化规律明显，随季节变化而变化。更多还原

【Abstract】 Forest swamp transformed in xtao xingan Mountains is come from Larch-Sphagum swamp thathas been remade through digging trench and draining. There are about 20 kinds of trace elements inthe pbot bedies in the community, in which elements of Mn, Zn,B,Cu, Co are the main ones in-fluened plants trowth. As for the amount of trace elements, there’s a law,i. e. the content of Mn>Zn>B>Cu>Co. There,s an obvious law about the content of trace element indifferent of the plants,i.e. the content of trace element indmerent organs obviously changes seasonally’更多还原
