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.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. The remote controller includes a fertilizer application switch for instructing an opening and closing operation to the calculated opening degree position of the shutter plate, and the fertilizer application switch is provided so as to be switched to a cleaning mode for fully opening or fully closing the shutter plate. Thus, the wireless communication control device of the fertilizer application device is provided.SELECTED DRAWING: Figure 1【課題】作業者が容易に効率よく扱うことができる肥料散布装置の電動作動部の操作部を提供する。【解決手段】肥料散布装置２の受信した電波の指令信号に応じて散布量調整部２２の作動を制御する制御部と、指令信号電波を送信する送信部を備えたリモコン装置３１とを有する無線通信制御装置であり、リモコン装置３１は、各散布条件から開度を算出するシャッタ板開度算出部を備え、算出されたシャッタ板の開度位置と散布条件の記憶部を備え、リモコン装置には、算出されたシャッタ板の開度位置まで開閉動作を指示する肥料散布スイッチが備えられ、肥料散布スイッチはシャッタ板を全開又は全閉にする掃除モードに切り替え可能に設けられている肥料散布装置の無線通信制御装置による。【選択図】図１
