FORMATION OF ARTIFICIAL SOIL FOR SLOPE

摘要

PURPOSE:To form artificial soil suitable for the cultivation and growth of plants in sloped ground by a method in which urethane polymer and water are sprayed onto the sloped ground and expanded. CONSTITUTION:Urethane polymer and water are sprayed onto sloped ground and expanded to form an artificial soil suitable for the cultivation and growth of plants. The urethane polymer should have preferably hydrophilic groups for forming water-holding hydrophilic expanded layers suitable for the growth of plants and also water should contain a water-soluble polypeptide to react with and expand urethane polymer. In this case, hydrophilic urethane foam layers having peptide matrixes are formed. The peptide matrixes of the urethane foam layers are biologically decomposed and cut to accelerate the formation of artificial soil.
