采用ECk－1型电化学参数采集系统原位长期连续测量红壤耕层的电导率。本文初步探讨了红壤耕层电导率的动态变化及其与耕作方式和施用石灰的关系．
The ECk-1 Electrochemical Parameters Acquisition System was used to measure the conductivity of red tillage in-situ for a long time. In this paper, the dynamic changes of the conductivity of topsoil in red soil and its relationship with tillage methods and lime application were discussed.
