Description

Technical Field

[0001] This utility model relates to a measuring device, and more particularly to an agricultural remote sensing measuring device. Background Technology

[0002] During transpiration, water enters the root system from the soil, is transported through the stem to the leaves, and finally dissipates into the air through the stomata of the leaves. Throughout this process, the sap in the plant stem is constantly in motion, and the sap flow rate reflects changes in transpiration. Therefore, measuring the sap flow rate of a plant stem can determine its transpiration rate. A sap flow meter, also known as a tree sap meter, is an instrument that measures the stem flow rate by heating the plant stem to calculate the transpiration rate. However, some existing instruments for measuring plant transpiration, after measuring the stem flow rate of trees, struggle to correlate it with ambient temperature, light radiation, and leaf density, making it difficult to conduct transpiration studies on trees in different conditions.
