Abstract

In order to meet the demand for detecting different ions of
one plant material at the same time in the future, it146s
of great significance to design a microelectrode array for the micro dynamic
ion flow detection of plant. This paper introduces a microelectrode array for
the ion flow detection based on Fick146s
law. The microelectrode array is composed of microelectrode, electrode holder,
fixed link of array, array framework, silver thread, wire, signal amplifier,
etc. Compared with the previous ion flow signal detection electrode, the microelectrode
array is characterized by detecting different ions at the same time with diversified
forms and high efficiency. It146s
found through the detection experiment of nine ions like K and NH4
in the maize root tip that the microelectrode array can meet the demand fordetecting
different ions at the same time. In addition, with the characteristics of high
efficiency and small error, it can describe the growth of plants more accurately.
