AI Technical Summary

Technical Problem

Traditional leaf water potential measurement methods are cumbersome and cannot achieve continuous dynamic monitoring, making it difficult to monitor the water status of plant leaves in real time and without damage.

Method used

An intelligent leaf water potential monitoring system based on a multi-component flexible film is adopted, which includes a flexible film sensing unit, a wireless transmission unit, and a remote monitoring terminal. The flexible film sensing unit collects the temperature, humidity, light intensity, and tension values ​​of the leaves, and transmits them wirelessly to the remote monitoring terminal for data processing and display.

Benefits of technology

It enables real-time, non-destructive, and accurate monitoring of plant leaf moisture status, providing a scientific basis for agricultural irrigation decisions and improving water resource utilization efficiency and agricultural management precision.
