PURPOSE: To provide a method for establishing a mulch layer capable of preventing water fall because of stable adhesion of a mulch material, making the mulch material into a solid structure after spray and sufficiently showing mulch effect without clogging a pump or a hose with the mulch material in establishing a mulch layer on the surface layer of a growing bed established on an uncovered inclined plane so as to maintain the environment of the established growing bed in an excellent condition. CONSTITUTION: In blending a slurry of a mulch material obtained by mixing the mulch material 61 with water and a polymer 62 having high water absorption properties, a binder 7 and a polyacrylamide-based polymer as an anionic polymer coagulant, transporting the mixed slurry by a pump under pressure and spraying the slurry to a face to be executed, a polyacrylamide-based polymer as a cationic polymer coagulant is mixed in a nozzle and sprayed to provide a method for establishing a mulch layer. |
