When the plant is higher than the evaporating dish body 1, the height of the evaporating dish body 1 needs to be adjusted with the bracket according to the plant canopy height change, so that the plant canopy and the water level in the evaporating dish body 1 are level. The specific operation method is: the height adjustable pull rod 95 can be pulled outward by holding the button 96, so that the height adjustable pull rod 95 drives the stop cap 97 to move inward, and then the evaporating dish body 1 can be held by hand, so that the level auxiliary adjustment detector structure 10 can be moved down to the upper part between the stop caps 97 of the lower layer, and the button 96 is released.

The position of the adjusting screw 103 inside the fixing nut 104 can be rotated by holding the rotating handle 106, so that the deep groove ball bearing 102 can be rotated inside the movable seat 101. At this time, the movable seat 101 drives the automatic reading cylinder-free measuring scale structure 11 to make the evaporating dish body 1 move. The horizontality is determined by the horizontal detector 107, and the adjustment operation is completed.

[0051] S103: Automatic reading of evaporation without measuring cylinder. The evaporation of the plant canopy inside the evaporating dish body 1 can be weighed and detected by the electronic scale 111, and the data can be displayed by the automatic reading without measuring cylinder measurement display screen 116.

When the plant height is less than the evaporating dish body 1, the bracket can be directly removed, and the evaporating dish body 1 can be placed on a flat plot next to the plant to be tested (to prevent tipping), and the canopy moisture can be directly measured with the evaporating dish body 1; when the plant is higher than the evaporating dish body 1, it is necessary to adjust the height of the evaporating dish body 1 with the help of the bracket according to the change of the plant canopy height, so that the plant canopy and the water level in the evaporating dish body 1 are level; the specific operation method is: the water level can be determined by the liquid level line 2, and the water level can be adjusted according to the change of the plant canopy height. To adjust the height position of the evaporating dish body 1, the height adjustable pull rod 95 is pulled outward by holding the button 96, so that the height adjustable pull rod 95 drives the stop cap 97 to move inward. At this time, the evaporating dish body 1 can be held by hand, so that the levelness auxiliary adjustment detector structure 10 moves down to the upper part between the stop caps 97 of the lower layer, and the button 96 is released.

The position of the adjusting screw 103 inside the fixed nut 104 can be rotated by holding the rotating handle 106 to make the deep groove ball bearing 102 rotate inside the movable seat 101. At this time, the movable seat 101 drives the automatic reading cylinder-free measuring scale structure 11 to make the evaporating dish body 1 move. The horizontality is determined by the horizontal detector 107 to complete the adjustment operation.

[0059] Step 3: Automatic reading of evaporation without measuring cylinder. The evaporation of the plant canopy inside the evaporating dish body 1 can be weighed and detected by the electronic scale 111, and the data can be displayed by the automatic reading without measuring cylinder measurement display screen 116. At the same time, the water level can also be determined by the liquid level line 2. The zeroing operation can be performed by pressing the zeroing button 115. Multiple measurements can be performed.

The method for using the automatic reading and height-adjustable evaporating dish according to claim 1, characterized in that: The method for using the automatic reading and height-adjustable evaporating dish specifically comprises the following steps: Step 1: Adjust the operation according to the change of plant canopy height. When the plant height is less than the evaporating dish body, the bracket can be directly removed, and the evaporating dish body can be placed on the flat land next to the plant to be tested, and the canopy moisture can be directly measured with the evaporating dish body; when the plant is higher than the evaporating dish body, it is necessary to adjust the height of the evaporating dish body with the help of the bracket according to the change of plant canopy height, so that the plant canopy and the water level in the evaporating dish body are level; the specific operation method is: the height adjustable pull rod can be pulled outward by the hand-held button, so that the height adjustable pull rod drives the stop cap to move inward, and then the evaporating dish body can be held by hand, so that the level auxiliary adjustment detector structure can be moved down to the upper part between the stop caps of the lower layer, and the button can be released. At this time, the reset spring releases energy, and the stop cap can be returned to its position, and the height adjustment operation can be performed. It can be fixed to the ground through the support rod and the fixed cone head, and the adjustment operation according to the change of plant canopy height is completed; Step 2: auxiliary adjustment and detection of the horizontality. The horizontality of the evaporating dish body can be detected in real time according to the horizontal detector. By rotating the position of the adjustment screw inside the fixed nut by holding the rotating handle, the deep groove ball bearing can be rotated inside the movable seat. At this time, the movable seat drives the automatic reading cylinder-free measuring scale structure to make the evaporating dish body move. The horizontality is determined by the horizontal detector to complete the adjustment operation. Step 3: Automatic reading of evaporation without measuring cylinder. The evaporation of water in the evaporating dish can be weighed and tested by an electronic scale, and the data can be displayed on the automatic reading without measuring cylinder measurement display screen. At the same time, the water level can be roughly verified through the liquid level line. The zeroing operation can be performed by pressing the zeroing button. Multiple measurements can be performed. The electronic scale can be turned on and off by the switch button, and the automatic reading without measuring cylinder measurement display operation can be performed. Step 4: Dust-proof adjustment and protection operations. According to the measurement requirements of the plant canopy, protection work can be carried out. By loosening the thumb screw, the position of the movable support rod inside the connecting tube can be moved and adjusted. After determining the height position of the protective plate, the thumb screw can be locked to play a blocking role through the retaining ring.
