种子库贮存作物种子的仓库。种子是播种下季作物的生产资料,在贮存期间,不仅要保证其不变质、不霉烂、不损耗、不掺杂，更重要的是保持种子固有的生命力。库房类型有房式仓、砖拱仓、土圆仓及机械化圆筒仓等（见筒仓），适宜于贮存稻、小麦、玉米、大豆、花生和棉等的种子；甘薯、马铃薯等的种薯一般采用窖藏法（见土窖）。随着农业生产的发展和贮藏技术的提高，种子库逐步向专门化、仓型多样化方向发展。库址选择 种子库宜选择在作物产区的中心和交通方便的地段，邻近种子繁育、生产和加工的基地，服务半径不宜太大。要求地势高燥，土质良好，水稻产区一般雨水多、地下水位高，库址更应选择在不受水淹的地点。此外还要有足够的场地满足库房、晒场、检验室等附属建筑物的需要。库房建筑 种子库建筑物的构造要注意隔热、防潮、通风和密闭。为便于清理种子、防止混杂和杜绝害虫的孳生,仓壁四周须平整光滑,并设置防鼠、防雀设备。每幢种子库面积以300～500平方米为宜，跨度9～12米,檐高4米左右。对于多品种的种子库，宜分成大小廒间,分别贮存，以防混杂。种子采用包装贮存，有时也可散装贮存。散装库的种子直接靠墙堆装，墙身受到种子的侧压力和摩擦力的作用，因此墙壁应有足够的强度，以保证安全。在地下水位高的地区，库房地坪应比库外地坪高30厘米左右。地面要光滑、坚实，具有防潮、保温性能，可采用沥青砂浆地面或平铺防潮砖地面。为提高墙壁抗湿渗透和隔热性能，砖砌外墙厚度应有37厘米，并加双面抹灰喷白。内墙面在种子的堆高部位抹沥青防潮，防潮墙面同地面衔接紧密。库房屋面构造要严密，以防鸟、虫从房顶或檐口进入库内，同时满足药剂熏蒸的要求。通常采用架空通风隔热屋面、双层砖筒壳屋面或假吊顶通风隔热屋面。纵墙大门的间距不应大于18～24米，宜南北对开，以利通风及搬运。门上设雨篷，门下设防虫槽和活动挡鼠板。种子库不宜靠自然采光。窗户的设置是为了通风。因此窗子的大小及位置高低要适当，关闭时密闭可靠，开启时便于通风，并设置防鸟铁丝网。
