Abstract：Aiming at the determination of soil salinization degree in the fields planting salt-tolerant crops uniformly and accurately,and the problems of uncertainty of saturation point during preparing saturated mud and instability of measuring its electrical conductivity,the response relationships of water content and electrical conductivity between saturated mud and soil leaching liquor were studied by laboratory tests and statistical a-nalysis.The response and conversion relationships of electrical conductivity and total salt content between satu-rated mud and soil leaching liquor with soil-water ratios of 1∶0.5、1∶1、1∶2.5、1∶3.5 and 1∶5.The results showed that in the coastal saline soil area,the water content,electrical(conductivity)of soil leaching liquor obtained by calculating soil porosity in field could not directly replace that of saturated mud,although their re-sponse relationship had reached the very significant level.The differences in electrical conductivity and total salt content between saturated mud and soil leaching liquor with soil-water ratio at 1∶1 and 1∶0.5 were the least,and there were very significant response relationships with the corresponding parameters of soil leaching liquor with soil-water ratio from 1∶0.5 to 1∶5.The correlation in electrical conductivity between saturated mud and soil leaching liquor with soil-water ratio at 1∶5 and that in total salt content of saturated mud and soil leac-hing liquor with soil-water ratio at 1∶1 were both the highest,and they could be converted by the best-fit linear models,which were ECe(mS/cm)=5.406EC1∶5-0.284 4 and TSe(g/kg)=0.836 4TS1∶1-0.135 9,respec-tively.
