贾思勰

贾思勰（xié）（？—？），齐郡益都县（今山东省寿光市西南），北魏农学家，官至高阳郡太守（今山东省淄博市临淄区一带）。

他精通农业科学，在复兴由于战乱而荒废的华北农业时，将旱地农业技术体系化，于北魏末年写成《齐民要术》一书。该著作由耕田、谷物、蔬菜、果树、树木、畜产、酿造、调味、调理、外国物产等各章构成，是中国现存的最早的、最完整的大型农业百科全书。

《齐民要术》

《齐民要术》是中国保存得最完整的古农书巨著，成书于东魏武定二年（544年）以后，另一说为533年至544之间。

书中分成10卷92篇，收录1500年前中国农艺、园艺、造林、蚕桑、畜牧、兽医、配种、酿造、烹饪、储备，以及治荒的方法，书中援引古籍近200种，所引《泛胜之书》、《四民月令》等汉晋重要农书现已失传，后人只能从此书了解当时的农业运作。

该书自出版后，受历朝重视，传遍海外后亦被常成为研究古史物种变化的经典(日本)东海大学教授.渡部 武. 关于《齐民要术》在日本的传播与接受... 。达尔文研究进化论时，曾参考一部“中国古代百科全书”，有说此书正是《齐民要术》。“齐民要术”可解作平民谋生方法，亦可解为治理民生的方法。

Jia Sixie (賈思勰) (fl. 530–544) was an agronomist during the Northern Wei Dynasty. He is the author of one of the earliest and historically most influential agricultural treatises, the Qimin Yaoshu 齊民要術 (often translated as “Essential Techniques for the Common People”). The text was notably one of the most systematically organized treatises on farming and animal husbandry, which was commonly copied and referred to by scholars from throughout the Tang dynasty until the Qing.

There are very little direct references of Jia in his agricultural treatise, as the only mention of him is a ten character long sentence that refers to him as the Governor of the prefecture of Gaoyang. There are still ongoing academic discussions surrounding where Jia was stationed as governor, as there were two Gaoyang prefectures located within the territory of Northern Wei; one in modern-day Hebei province, and one in Yidu district. Recent studies have also noted two figures from Yidu sharing Jia's family name who were listed in the Weishu as court officials, leading many scholars to generally agree that Jia was likely a member of the same family as the two mentioned officials, Jia Sibo (d. 525 CE) and Jia Sitong (d. 540 CE).
