PROBLEM TO BE SOLVED: To practically use felled tree chips and a cut on the field of a greening site as a part of a spraying raw material, and to conduct greening spraying with high efficiency for constructing land at a great distance from a spray nozzle by a spiral force-feeding means. SOLUTION: The greening spraying force-feeding device for the ground has a main raw-material force-feeding section 12 for forcibly feeding a main raw material M1 containing site-generating plant materials, a fertilizer and seeds, a carrying means 14 containing carrying hoses 22 being connected to the main raw-material force-feeding section 12 and guiding the main raw material towards a spray nozzle 24 installed on the front end side, a moisture raw-material force-feeding section 16 for joining interposed at the carrying means 14 and arranged at a front position in the vicinity of the spray nozzle 24, and a spiral force-feeding means 18 forwarding the main raw material M1, flowing the main raw material spirally in the carrying means 14. Raw materials are sprayed against the ground from the spray nozzle 24, forcibly feeding the main raw material M1 and a moisture raw material M2 for joining spirally in the carrying means 14. The fluidity of a fluid in the hose is ensured by force-feeding, and the adhesion of a spraying raw material onto the interior wall of the hose is prevented.
