土壤电导率测量方法的研究与仿真

摘要

This paper put forward a measuring method of pop calibration of conductivity signals. Through checking and analyzing the pop signal, the true and false of the saltus step signals were restored to ensure the real test results. The simulate results show that this method can obtain much more accurate soil conductivity, and improve the measurement accuracy under the condition of larger soil water - soluble molecules.This paper put forward a measuring method of pop calibration of conductivity signals.
