摘要:

作者以山东省禹城市小麦-玉米轮作地区为研究对象,2007-2020年连续14年秋收后(10月份)开展农田土壤调查。通过系统采集0-20 cm耕层土壤样品,在中国科学院禹城综合试验站采用标准化分析方法测定关键指标:土壤pH值(水土比5:1浸提法)、全氮(凯氏定氮法)、速效磷(碳酸氢钠浸提-钼锑抗比色法)及速效钾(乙酸铵浸提-火焰光度法),得到山东省禹城市土壤养分实测数据集(2007-2020)。该数据集包含禹城市以下数据:2007-2020年每年土壤采样地点、土壤pH、全氮、速效磷、速效钾和土壤类型数据。该数据集以.shp、.gdb格式存储,由94个数据文件组成,数据量为2.26 MB(压缩为1个文件,1.17 MB)。
