Solid sand method for vegetation greening

摘要

PPROBLEM TO BE SOLVED: To provide a construction method for solidifying vegetation greening sand preventing wind erosion to enable vegetative greening even in an area lack of rich underground water and suffered from gusty wind erosion, and excellent in construction property and economical efficiency. PSOLUTION: The construction method for hardening vegetation greening sand comprises spraying a vegetative greening composition containing seeds, fertilizer, a water-holding agent and a fertilizer-holding agent on the surface of the desert, spraying an aqueous solution for solidification composed of hydrophilic polyurethane resin and water so as to form a solidified porous sand layer. The thickness of the porous sand layer is 5-50 mm, and the concentration of the hydrophilic polyurethane resin in the aqueous solution for solidification is 2-7 wt.%. PCOPYRIGHT: (C)2009,JPO&INPIT
