《天工开物·上篇·乃粒》
旱稻的稻种要在初秋时收进谷仓，如果中午在烈日下曝晒，种子内的热气还没散发就装入谷仓，之后封闭谷仓又太急的话，稻种就会带着热气过冬。
凡早稻种，秋初收藏，当午晒时烈日火气在内，入仓廪中关闭太急，则其谷粘带暑气。
The seeds of dry rice need to be stored in the granary in early autumn. If they are exposed to the sun at noon, the heat in the seeds will not be dissipated before they are put into the granary, and if the granary is closed too quickly, the seeds will carry the heat through the winter.
