Silkworm Rearing (Song Silk Weaving)

Timeline

1. c. 1000–1127Kaifeng and Hebei East Circuit · Central PlainsThe Northern Song established bodies such as the Lingjin Yuan in the capital and the circuits, regulating silkworm eggs, mulberry leaf supply, and loom specifications; the private sector also formed ward-based rearing–reeling–weaving chains.
2. c. 1190–1200Lin'an Prefecture and Huzhou · JiangnanIn the 1190s the Southern Song, with its capital at Lin'an, carefully managed spring and summer silkworm seasons in Jiangsu–Zhejiang; standards for rearing frames, temperature control, and cocoon selection supported exports of luó, juan, and satin and maritime trade, while sericulture taxes and the he-mai procurement system reached deep into the countryside.
3. 1147–1200Gaoyou and northern Jiangsu · JiangsuQin Guan's Can Shu recorded egg bathing, incubation, heavy-feeding management, and rearing-frame structure, becoming a model for later sericulture literature; by the 1190s local sericulture regulations widely cited similar technical points for seasonal production scheduling.
