《授时通考·天时门》
shoushi Tongkao tianshimen《授时通考·天时门》《授时通考》是中国清代官方编辑的一部大型农书。内容分为八门。其中《天时门》共六卷，汇集了农业气象方面的记述。《天时「1》中总论二卷，大量摘录了前人著作中有关农时、节气和物候的记述和农家谚语。后四卷依春、夏、秋、冬，按月分述各月天象、物象及气候状况，并列述播种、扦插、栽种、浇培、收藏等农事活动。此外，在《谷种》、《农余》两门里也有一些农业气象记述。《授时通考》体裁严谨，引证周详，附有很多插图。原有武英殿刻本和翻刻本，后又有富文书局、上海实业研究社的石印本。目前流行的是1956年中华书局的翻印本。 (朱履宽)
