Timeline

  1. c. 1012–1100Jianghuai and Fujian · JianghuaiUnder Zhenzong's reign, early-ripening drought-tolerant rice was introduced from Champa and promoted in Jianghuai and Fujian alongside pro-agriculture policies, shortening the growth cycle and leaving a time window for subsequent double-cropping.
  2. c. 1190–1200Liangzhe Circuit and Jiangnan East Circuit · JiangnanIn the 1190s, Jiangnan regions bred local late-rice and glutinous-rice lines based on Champa rice; paddy-field areas commonly practiced early-late rice succession or rice-wheat rotation, with seedling transplanting and seed selection forming village-level knowledge transmission.
  3. 1206–1210Jiangnan West Circuit · JiangxiChen Fu's Nong Shu systematically recorded seed soaking, sprouting, seedling raising, and water management, reflecting that Southern Song rice varieties were already classified and used by terrain, water source, and maturity; agricultural documents also began to tabulate circuit-level good harvests and per-mu yields.
