摘  要:
该文选用2011—2015年度内蒙古巴彦淖尔市7个旗县(区)146 400hm2耕地采集的土壤样品,分析汇总全市耕地速效钾含量,速效钾测定方法采用LY/T 1236-1999《森林土壤速效钾的测定》方法。结果表明,全市速效钾含量均值为213mg/kg,7个旗县(区)速效钾含量均值最高为224mg/kg,最低为162mg/kg。基于当地土壤肥力丰缺指标和1982年全国第二次土壤普查巴彦淖尔地区测定结果,评价该市农田土壤速效钾含量属中等水平,但有下降趋势,建议采取有效措施来提高农田土壤钾素水平。

摘  要:
This article selects the soil samples which were collected from 146 400hm2 of arable land in 7 counties(districts)in Bayannur city of Inner Mongolia in 2011—2015 years. The content of available K in the land of thecity was analyzed,using the"determination of available K of forest soil"method to measure available K. The resultsshow that the mean available K content in the whole city is 213mg/kg,and the highest in these 7 countries is 224mg/kg,the lowest is 162mg/kg. Based on the local soil fertility abundance index and the determination result of Bayan-nur City in the second general soil survey in 1982,it is evaluated that the available K content of the city is in themedium range with a downtrend. It is suggested to take some effective measures to improve the soil potassium fertility.
