摘 要：
运用烘干法对天津不同地区土壤含盐量进行测定,对其结果与2265FS土壤原位电导率仪测定的土壤电导率和土壤浸提液电导率进行相关分析,并建立线性回归模型。结果表明,2265FS电导率仪测定的土壤溶液电导率与土壤含盐量之间(r1)以及土壤浸提液电导率与土壤含盐量之间(r2)极显著正相关。2265FS电导率仪测定结果可靠,在实际工作中可以通过该仪器测得的土壤溶液电导率和土壤浸提液电导率对土壤含盐量进行快速测定,其测定回归模型分别为y赞=0.152 6+6.941 7×10-5x和y赞=0.097 3+1.146 3×10-4x,前者更加快速、简便,后者测定结果更为精确。

摘 要：
Abstraact: The soil salinity in different regions of the Tianjin city was measured with drying method. The correlation between the soil in situ conductive meter measured by 2265 FS and the soil salinity was studied. A linear regression model was established. Results showed that the conductivity of the soil solution measured by 2265 FS was significantly positively correlated with and the soil salinity(r1). There was a case the soil extract(r2). Comprehensive analysis showed that the results measured by 2265 FS were reliable. It could quickly measure the soil salinity through measuring electrical conductivity of the soil solution and soil extract with the machine. The regression models were y赞(%)=0.152 6+6.941 7×10-5x and y赞(%)=0.097 3+1.146 3×10-4x. The former was faster and easier, while the latter was more accurate.
