In ancient China, sea salt was mainly made by fire and sun drying. In the early stage, sea salt was mostly made by fire. In the Ming Dynasty, the mode of sun drying appeared sporadically in coastal areas. At that time, the sun drying technique was adopted by some salt fields in Huaibei, Changlu, Shandong, Fujian, Zhejiang, Guangdong and other places. In the Qing Dynasty, the sun drying method was further promoted, and the salt-flat drying method appeard in the late Qing Dynasty and the Republic of China. There were different ways of sun drying methods, such as ditch-salt flat drying, well-salt flat drying, the brick-pool drying, stone drying, board drying and other salt flat drying. This paper is mainly based on the two pieces of paper cultural relics involving "Yuanpu Salt Field" and "Chuanchang Salt Field" collected by Yancheng China Sea-salt Museum, to explore the development history and the management of the board drying in the late Qing dynasty and the Republic of China. |
