The present invention relates to Tyvek mulching paper and its installation method, wherein the mulching is installed on soil or medium in which crops are planted so as to increase the coloring and sugar content of all fruit trees or fruits of a crop by diffuse reflection of sunlight incident on an orchard or farmland. In the paper, a mulching support stage which is wound or folded in a roll format, and is installed on the soil or culture medium on which the crops are planted by unfolding as needed； Fixing portions provided along the longitudinal direction on one or both sides of the mulching support end； And a vinyl tube inserted to be replaceable inside the fixing unit and generating a load by injecting water to fix the installed mulching support end, and the mulching support end has heat retention, chemical resistance, moisture permeability, waterproofing, and high performance. In the method of installing Tyvek mulching paper made of Tyvek, which is a high-density polyethylene material having reflectivity, and configured as described above, the method comprising: a preparation step of preparing Tyvek mulching paper according to the soil or medium in which the crop is planted； Mulching step of spreading the Tyvek mulching paper on the soil or medium； A fixing step of injecting water into the vinyl tube inserted into the unfolded Tyvek mulching paper to fix the Tyvek mulching paper so that it does not deviate from the unfolded position or there is a gap； Including the fixing pin installation step of installing a fixing pin so that the fixed Tyvek mulching paper can be fixed to the soil or culture medium without being heard by the wind. And it relates to a Tyvek mulching paper that increases the sugar content and can be installed smoothly with a small number of personnel, and a method of installing the same.본 발명은 타이벡 멀칭지 및 그 설치방법에 관한 것으로, 과수원 또는 농지에서 입사되는 햇빛을 난반사시켜 유실수 또는 농작물의 전체 과수 또는 열매의 착색 및 당도를 높이도록 농작물이 식재된 토양 또는 배지 위에 설치되는 멀칭지에 있어서, 롤 형식으로 권취되거나 접이식으로 이루어지며, 필요
