《农政全书》 / Nongzheng Quanshu

《农政全书》 enters the wiki through EP259 与苗师傅漫谈徐光启：四百年前如何让人变聪明？ as [[XuGuangqi|徐光启]]’s agricultural and famine-oriented work. The episode uses it to argue that Xu’s value is not only “让人变聪明” through mathematics, but also “让人吃饱” through concrete agricultural knowledge.

The source ties the book to climate cooling, crop failure, famine cycles, and the search for survival foods such as taro, water chestnut, locust-tree flowers, and sweet potatoes. That makes the work the anchor for [[AgriculturalReliefStatecraft|农政救荒]] rather than only an agronomic encyclopedia.

The page also connects Xu’s agricultural writing to the wiki’s broader agriculture branch. In this episode, agriculture is a high-stakes knowledge system where state responsibility, local food security, and experimentation matter under environmental stress.
