Plant Physiological Status Monitoring System and Its Application in Greenhouse

The plant physiological status is affected by the change of greenhouse environment, hence, the physiological status is regarded as feed back information from plant. Based on the point, the purpose of monitoring the physiological status and constitution of the system was described. The system was employed to monitor the change of environment and synchronously record the physiological status. Then the relation ship between plant surface electrical potential and the change of greenhouse environment was discussed.
