| 摘 要： | 2009—2011年，鄂温克族自治旗实施国家测土配方施肥项目，采集了4个乡镇6种主要土壤类型的1676个耕层土壤样品，测试分析了土壤有效硫含量。结果表明：该旗耕层土壤有效硫平均含量为13．1mg／kg，属于中等水平。锡尼河镇与辉苏木土壤有效硫含量缺乏面积较大。沼泽土有效硫含量最高，风沙土最低。农业生产中，在施用含氮、磷、钾配方肥的基础上，应该有针对性地配合施用硫肥。

| Abstract: | The national project of formula fertilization by soil testing was implemented of Ewenki Autonomy Banner in 2009- 2011.1676 soil samples of 6 soil types were taken from 4 towns and their available sulfur contents were analyzed. The results showed that the average available sulfur contents were 13.1mg/kg, belonged to the medium level. The lacking of soil available sulthr contents were mostly distributed in Xinihe town and Hui town. Available sulfur content of boggy soil was the highest, lowest of aeolian sandy soil. Based on the application of nitrogen, phosphorus, potassium fertilizer, sulfur fertilizer should be applied in purpose. |
