Preparation of soil coating liquid, soil coating liquid for solidification of soil for dust scattering prevention, yellow dust prevention and desert greening and soil application method using the same

摘要

The present invention relates to an environmentally-friendly soil spray solution which solidifies soil to prevent dust scattering and yellow sand and achieves desert afforestation, and to a process for preparing the soil spray solution, and to a method for spraying a solution over soil, wherein the soil spray solution is produced by mixing water and a water-soluble organic binder, and the thus-produced soil spray solution in an aqueous state is sprayed over the desert or a dry layer to solidify soil. In addition, the present invention provides a process for preparing the environmentally-friendly soil spray solution which solidifies soil to prevent dust scattering and yellow sand and achieves desert afforestation, and a method for spraying the solution over soil using same, wherein said process and said method comprise the steps of dissolving polyvinyl alcohol (PVA) and a softener (citric acid or the like) into water such that the polyvinyl alcohol has a weight ratio (wt%) of 1% to 10% with respect to the weight of water, and the softener has a weight ratio (wt%) of 0.1% to 10% with respect to the weight of water, to obtain an aqueous solution; mixing an environment-friendly pigment to the aqueous solution, adding soil amendments serving as a vegetation element, such that the soil amendments have a weight ratio (wt %) of 0.1% to 20% with respect to the weight of water, and stirring the mixture to produce a fourth soil spray solution; stirring seeds of plants into the fourth soil spray solution to produce a sixth soil spray solution; and spraying the thus-produced sixth soil spray solution in an aqueous state over the desert or a dry layer.
