Current device for automatically generating nitrogen fertilizer based on smart agriculture

The invention discloses a current device for automatically generating nitrogen fertilizer based on smart agriculture. The current device comprises a device body, two bilaterally symmetrical support columns are fixedly arranged on the upper end surface of the device body, protection cavities enabling the upper and lower end surfaces of the support columns to be communicated are arranged in the support columns, a mounting block is fixedly arranged between the two support columns, a water flow cavity enabling the upper end face and lower end face of the mounting block to be communicated is formedin the mounting block, and a spray head communicated with the water flow cavity is fixedly arranged at the upper end of the mounting block. The device is easy and convenient to operate and simple instructure. Current excitation and nitric oxide absorption can be realized through a series of mechanical actions as long as the device is mounted in a greenhouse and connected with an alternating current power supply and a mot
