Field experiment was conducted in South of Xinjiang Uygur Autonomous Region to find efficient method to measure soil solution concentration.Soil water content was measured by tensiometer.Soil water and soil were sampled by soil drill and soil water extractor with the same depth,respectively.Soil EC_1:5 and EC_ewere measured by conductivity meter.Soil solution concentration was measured by flame photometer and titrmetric method.Linear regression analysis on measured data was carried out by means of SPSS 17.0.The results showed that there was a significant linear relationship between EC_1:5and soil total salitv when EC_1:5 was 0-10000 μS/cm;EC_ecould be calculated by EC::through the coefficent of relationship which was decided by soil saturation content1:5was 0-3 000 μS/cm,there was a significant linear relationship between soil solution concentration and EC_1:5.Therefore,on the basis of measuring EC_1:5of the soil samples,and identifying the conditions under which it can be applied,the EC_e and C can be directly calculated through correlation.
