In existing technologies, when the water level in the storage container is lower than the height of the outlet pipe, water cannot enter the evaporation dish, resulting in irrigation failure. At the same time, existing methods cannot simulate the irrigation conditions for crop growth.
The system employs multiple incubators and a curved tube design, combined with a soil moisture sensor and siphon effect. Water is introduced into the incubators through the curved tubes, and water replenishment is controlled by a solenoid valve to simulate the growth of crops in saline-alkali land.
It enables precise control of crop humidity in saline-alkali land, simulating real growth conditions and ensuring the convenience and effectiveness of irrigation.
