Demonstration Lysimeter

The container filled with soil and plants is installed on the hydraulic sensing device in the base, which is connected to the graduated water column installed above the lysimeter. Any soil type and various crops can be placed in the container. Weak. Of course, when the temperature is very high and the light is very strong (reaching the light saturation point), the stomata are closed and the plant’s hydration effect is almost stopped. This is an adaptation of the plant to maintain water in the body. Used to monitor system weight changes caused by evapotranspiration. Despite its simplicity, the instrument has a high degree of sensitivity. Under normal circumstances, if the temperature around the stomata is high, the light is strong, and the humidity is small, the degree of stomata opening will be greater, and the transpiration will be stronger; if the temperature around the stomata is low, the light is weak, and the humidity is high, the degree of stomata opening will be small, and the transpiration will be greater.
