该数据是在2010年10-11月份根据2009年石河子土地利用图以及土壤分布图选取120个耕地样点进行室内实验分析所得。主要有：（1）石河子垦区典型地块的土壤盐分和电导率数据。（2）石河子垦区典型地块土壤的铵态氮、速效磷、速效钾数据。\n在三个典型样地各取40个土壤样本，总共取样120个。每个样本取三个土样混合，每个土样取0-10cm（耕层表层）和10-20cm（耕层根层）两层。包含了土壤表层和耕层的铵态氮（ppm）\\速效磷（ppm）\\速效钾（ppm）\\含盐量（%）\\电导率（μs/cm）等数据.", "ds_source": "
采用ＴＦＣ智能普及型土肥测试仪（此仪器已经利用传统滴定法进行校正）测定土壤含盐量\\电导率\\速效养分(包括铵态氮、速效磷及速效钾)等。
", "ds_process_way": "每个样本取3 个土样混合，每个土样取0~10 cm（耕层表层）和10~20 cm（耕层根层）两层，鉴于地块与地块之间的形状差异以及地块内部土样的差异，取样方法选取典型的蛇形取样法，根据地块大小及形状选取不同的方式。将取回的土样自然风干，然后将土样研磨，过1 mm 筛子，称取10 g 土样待测。将待测土样加蒸馏水后过滤，对滤液进行标准试剂处理后用TFC 智能普及型土肥测试仪，测量土样的各种指标.
