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。
After the transformation of the small Hinggan Mountains forest swamp is Larix larch - peat bog moss ditch drainage drainage transformation. Test analysis of marsh plants in more than 20 kinds of trace elements, the plant growth and development of the most influential elements are manganese, zinc, boron, cobalt and copper. They are significantly different levels in plants. But there are also common, that is, manganese> zinc> boron> copper> cobalt. The content of major trace elements in various organs of plants is also different. The regular pattern of the trace elements in the organs is obvious and varies with the seasons.
