摘要
以5∶1的水土质量比浸提潮间带土壤,质量法测定的土壤盐度(质量分数),与电导法测定的稀释了5倍的土壤浸提液(5∶1水土质量比)的电导率值之间有极显著的相关性。质量法实测的土壤盐度与电导率计算的土壤盐度之间的相对误差多在5%以下。因此,用电导法测定潮间带土壤盐度不失为一种简便、快速的方法,尤其是样品数较多时更可节约时间。
There was significantly correlation between soil salinity in intertidal zone obtained by mass method (the ratio of mass of water to soil is 5∶1) and electric conductivity of extracting solution diluted five times by electric conductivity method The relative errors were almost below 5% between soil salinity measured by the mass method and the ones calculated by electric conductivity. So, electric conductivity method is a simple and rapid method for measurement of soil salinity in intertidal zone after defining the regression equation between soil salinity and electric conductivity. Plenty of time can be saved by electric conductivity method when soil samples are excessive.
