Zusammenfassung:PROBLEM TO BE SOLVED: To properly spray a chemical solution adjusted to an interval between crop ridges without the necessity to replace a spray rod, even when the interval between the crop ridges varies. SOLUTION: The spray rod 14 is structured of a plurality of spray pipes 20 aligned in a row as a spray pipe array and at least one piece of jet nozzle 23 is mounted on each of the spray pipes 20. In addition, the adjacent spray pipes 20 are connected to each other by means of a pliable connecting pipe 21, and each of the spray pipes 20 is installed, in a movable manner, along beams 17, 19. In this case, each of the adjacent spray pipes 20 is arranged at an alternately deviated position from the other so that each of the spray pipes 20 can be superposed over the adjacent spray pipe 20 in the moving direction.
