通过对吉林西部3个工作区土样的微量营养元素全量、有效量以及土壤pH值和有机质含量的测定,分析了土壤微量营养元素有效量特征及其影响因素结果表明,吉林西部有效B基本不缺乏;有效Mn含量极丰富;有效Cu含量农安极丰富,明显高于其它2区,大安有效Cu含量样点间差异较大;土壤有效Zn基本不缺乏;有效Mo严重缺乏,且地区差异性较大;吉林西部有效Fe含量极丰富.土壤有效Mn、Cu和Fe含量受全量控制;B、Zn 元素有效量受土壤pH值的制约;土壤有机质则与有效Mn和Fe呈极显著正相关.

Based on the assay of the total content and available content of the trace nutrient elements and the soil pH and organic matter of the soil samples,the characteristic of the available content of the trace nutrient elements and their affecting factors are studied.The results show that the available B in western Jilin is in a middle level,the content in Nong'an is higher than that in the others;the available Mn is extremely abundant;the available Cu in Nong'an is obviously higher than other areas,and the content in Da'an differs greatly;the available Zn is in a middle level;the severe shortage of available Mo differs between different areas;and the available Fe is extremely abundant.The available Mn,Cu and Fe have significantly positive correlation with their total content;the available B has significantly positive correlation with pH,and Zn has obviously negative correlation with pH;the available Mn and Fe had significantly positive correlation with soil organic matter.
