小兴安岭改造后的森林沼泽是兴安落叶松－泥炭藓沼泽经挖沟排水改造而成．测试分析表明该沼泽土壤与植物中含微量元素２０余种．对植物生长发育最有影响的元素为锰、锌、硼、铜、钴五种．它们在土壤与植物中的含量有明显差异，但也有共性，即锰＞锌＞硼＞铜＞钴．土壤各层次与植物各器官中的微量元素含量亦有不同，时空和季节变化规律明显，本项工作对兴安落叶松生产量的提高有重要意义
Small Hinggan Mountains after the transformation of the forest swamp is Larix larch - peat bog moss ditch drainage drainage transformation made. Test analysis shows that the swamp soil and plants contain more than 20 kinds of trace elements. The most influential elements of plant growth and development of manganese, zinc, boron, copper, cobalt five. Their content in soil and plants are significantly different, but there are also common, that is, manganese> zinc> boron> copper> cobalt. Soil levels and plant organs of trace elements also have different content, spatial and temporal changes in the law significantly, the work of Larix gmelinii production is of great significance
