补充资料: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。
