摘　　要：为掌握黑龙江和东北地区土壤养分资源现状及存在的问题,于黑龙江省大庆市杜尔伯特蒙古族自治县(杜蒙)、吉林省松原市扶余市(扶余)、吉林省长春市九台区(九台)三个地区玉米田地进行土壤肥力情况调查,采样分析土壤中有机质、硝态氮、有效磷、速效钾等指标的质量分数,以及土壤水分和pH值。结果表明,杜蒙土壤有机质含量平均值为20.7 g/kg。扶余土壤硝态氮含量平均值为50.30 mg/kg,速效钾含量平均值为215.89 mg/kg。九台土壤有效磷含量平均值为51.29 mg/kg。研究结果能为黑龙江和吉林地区玉米作物种植施肥管理提供依据和数据支持。In order to understand the current situation and existing problems of soil nutrient resources in Heilongjiang and Northeast China,a soil fertility survey was conducted on corn fields in three areas:Durbert Mongolian Autonomous County(Dumeng)in Daqing City,Fuyu City(Fuyu)in Songyuan City,Jilin Province,and Jiutai District(Jiutai)in Changchun City,Jilin Province.Samples were taken to analyze the quality scores of organic matter,nitrate nitrogen,available phosphorus,and available potassium in the soil,and soil moisture and pH value.The results showed that the average organic matter content in Dumont soil was 20.7 g/kg.The average nitrate nitrogen content in Fuyu soil is 50.30 mg/kg,and the average available potassium content is 215.89 mg/kg.The average available phosphorus content in Jiutai soil is 51.29 mg/kg.The research results can provide basis and data support for the fertilization management of corncrop cultivation in Heilongjiang and Jilin regions.
