土壤含水率和盐分对土壤电导率的影响

Experimental Survey for the Effects of Soil Water Content and Soil Salinity on Soil Electrical Conductivity

基于电流 -电压四端法的“polar- dipole array”形式 ,以壤土作为研究对象 ,对土壤含水率和土壤盐分与土壤电导率之间的相互关系进行了试验研究。结果表明 ,在土壤盐分和含水率 2个相关因素中 。

By using one type of four electrode sensors, called “polar dipole array”, the relationship among soil water content, soil salinity and soil electrical conductivity was investigated. The test results showed that in most cases soil salinity can be assessed directly from the measurement of soil electrical conductivity even though soil electrical conductivity is a variable determined by a combination of soil water content, soil salinity and soil texture, soil compaction and so on.
