The present invention relates to a natural salt field in which the ground is heated and a natural salt production method using the same. More specifically, the ground is heated to produce the natural salt by evaporating the brine transferred to the crystal ground with heating heat and solar heat. It relates to a sun salt salt and a sun salt production method using the same. To this end, the present invention is installed to prevent the mixing of salt water and soil foreign matter on the crystal ground of the salt field, and the bottom contact of the salt floor is installed in contact with or spaced apart from the bottom and heated by the heating means and the heating heat In the solar salt comprising a heat transfer plate for transmitting to the salt floor and the power production unit is installed on one side of the crystal paper to produce power supplied to the heating means, the salt floor is a sealing treatment so that the inflow of brine to the heat transfer plate is blocked. The heating means is coated to block contact with the brine, and the top of the crystal paper is installed to move to one side is provided with a salt opening and closing portion for opening and closing the upper side of the crystal paper, the salt opening and closing portion at the corner of the crystal paper The two guides are installed in one set so that the guide frames, which are erected and installed on the upper part, are inclined. One pair of the support frame formed longer than the other pairs, the upper sheet for opening and closing the upper side of the crystal paper while being guided to the inclined guide frame, and moving means installed in the guide frame inclined to move the upper sheet Characterized in that consisting of.본 발명은 지반이 가열되는 천일염전 및 이를 이용한 천일염 생산방법에 관한 것으로, 더욱 상세하게는 결정지로 이송된 염수를 지반을 가열하는 히팅열과 태양열로 증발시키도록 하여 천일염을 생산하도록 한 지반이 가열되는 천일염전 및 이를 이용한 천일염 생산방법에 관한 것이다.이를 위해, 본 발명은 염전의 결정지 지면상에 염수와 지반 이물질의 혼합을 방지하도록 설치된 염전바닥재와, 상기 염전바닥재의 하부에 면접촉 또는 이격되게 설치되어 히팅수단에 의해 히팅되고
