ZM7313 Demonstration Lysimeter didactic equipment Fluids Engineering Training Equipment
1. Performance parameters
Dimensions: 472mm*472mm*770mm
Weight: <20kg
Inner diameter of transparent water pipe: 2.5mm
2. Product introduction
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. 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. 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.
3. Completable training projects
1. Monitor system weight changes caused by evapotranspiration
2. Study the factors that affect the strength of transpiration: temperature, light and humidity, etc.
