Three-dimensional cultivation system, cultivation method and dehumidification device

The invention relates to a three-dimensional cultivation system, a cultivation method and a dehumidification device. The three-dimensional cultivation system at least comprises a cultivation frame. The cultivation frame is divided into at least two cultivation layers in the vertical direction through at least two cultivation plates. A plurality of ventilation units penetrating through the cultivation plates and humidity sensors for monitoring the humidity of the cultivation layers are arranged on the cultivation plates. The humidity of each cultivation layer of the cultivation system is obtained through the humidity sensor, and the humidity adjusting scheme is selected according to the humidity requirement of the plant. The humidity adjusting scheme not only adjusts humidity in a single cultivation layer, but also relates to environment connectivity and interactivity among multiple layers of plants in the vertical direction. When the environment humidity in a single cultivation layer is adjusted, in the proce
