SOLUTION: The chemical jetting nozzle is equipped with a nozzle tube having jet holes for jetting the chemicals to a slit form extending circumferentially on the outer periphery of the nozzle tube. The nozzle tube is attached to a machine equipped with travel wheels so as to incline diagonally downward toward the side opposite from the advancing direction of the machine as the nozzle tube heads toward the leading front side. In addition, the nozzle tube is disposed oscillatably at a prescribed angle in a vertical direction in relation to the machine and the nozzle tube of the chemical jetting nozzle is energized by means of a coil spring in such a manner that its leading front side heads downward.
