PROBLEM TO BE SOLVED: To provide an electric operation unit of a fertilizer application device that can be handled by a worker efficiently and easily, and provide the electric operation unit of the fertilizer application device that can easily be responded when an application condition is changed.SOLUTION: A wireless communication control device has a control unit for controlling an application amount adjusting unit 22 according to a command signal of a radio wave received by a fertilizer application device 2, and a remote controller 31 with a transmission unit for transmitting a command signal radio wave. The remote controller 31 includes a shutter plate opening degree calculation unit for calculating an opening degree from each application condition. The wireless communication control device includes a memory unit of an opening degree position of a calculated shutter plate and the application condition, and the memory unit can store two or more combinations between the opening degree position of the shutter plate and the application condition. The wireless communication control device also includes a control unit capable of calling and changing in a state capable of transmitting a command signal by a call switch, re-calculating the condition when changed, and capable of being replaced to the condition and the opening degree position by the memory unit.SELECTED DRAWING: Figure 1 |
