《王祯农书》现存四库本系统的版本包括文渊阁本、文溯阁本、文津阁本、文澜阁本（存两卷），以及武英殿本和闽本、广雅本两个外聚珍本。作为四库本系统的一个典型案例，文章通过对《王祯农书》以上诸版本异文详细汇校，在展示其文本形成和流变过程的基础上，进一步揭示了四库本系统抄校、刊印的复杂过程。同时也指出四库时代的校勘理念不自觉地融会了段玉裁所谓的“立说之是非”，而这一点实际上还影响着现今的校勘实践。

The Wang Zhen Nong Shu, or Agricultural Treatise of Wang Zhen, exists in various editions within the Si Ku Quan Shu system, including the Wen Yuan Ge edition, Wen Su Ge edition, Wen Jin Ge edition, Wen Lan Ge edition (with two volumes preserved), and the Wu Ying Dian edition, as well as the Min edition and Guang Ya edition, which are two rare editions from outside the system. As a typical case within the Si Ku Quan Shu system, this paper meticulously collates the textual variants of the above editions of the Wang Zhen Nong Shu. By showcasing the process of its textual formation and evolution, it further reveals the complexities involved in the collation and printing of the Si Ku Quan Shu editions. Additionally, it points out that the textual criticism concept of the Si Ku Quan Shu era unconsciously integrated the principle of 'establishing right and wrong' advocated by Duan Yucai, which continues to inf luence present-day textual criticism practices.
