Embodiment Construction
[0020] like figure 1 As shown, the present invention includes: a water storage device 1 , a replenishment water tank 2 , a data collector 3 and an external power supply 4 . The water storage device 1 is installed at the position of the cutout 5 in the xylem of the tree trunk, and a cavity 11 for storing water communicated with the cutout 5 is arranged on the water storage device 1 . The replenishing water tank 2 is used for automatically replenishing water to the water reservoir 1, and a probe 21 (ie, a water level gauge) for measuring water level changes is arranged in the replenishing water tank 2 to measure the water level change of the replenishing water tank 2 . The data collector 3 is used to receive and record the water level change information collected by the probe 21 . The data of the water level change in the supplementary water tank 2 is continuously recorded by the data collector 3, so that the dynamic change of the xylem sap flow of the trunk can be automaticall...
