将水稻和大白菜种子装在牛皮纸袋中与一定量的干燥剂（硅胶或生石灰）密封于铝箔袋或磨口玻璃瓶中进行干燥，可使种子水分达到超干燥水平（水分低于５％）。该方法利用种子包装容器作干燥器，使干燥过程在体积很小的密封容器中进行，不但节约了干燥成本，而且可以同时干燥大量种子。采用生石灰作干燥剂成本很低，但容易使种子受到伤害。用硅胶作干燥剂虽然单价较高，但通过重复利用，可以使干燥成本下降。两种密封容器均可用于保存超干燥种子。但铝箔袋比玻璃瓶轻便，体积小，易于密封。因此，在有条件的情况下，建议用硅胶和铝箔袋作为种子超干燥的干燥剂和包装容器 Sealed rice and cabbage seeds in a kraft paper bag with a certain amount of desiccant (silica gel or quicklime) are sealed in aluminum foil bags or ground glass bottles for drying to achieve ultra-dry moisture levels (less than 5% moisture) . The method uses a seed packaging container as a dryer, which allows the drying process to be carried out in a small sealed container, not only saving the drying cost, but also drying a large number of seeds simultaneously. The use of quicklime as a desiccant low cost, but easy to damage the seeds. With silica gel as a desiccant although the unit price is higher, but by repeated use, you can make the drying costs down. Both sealed containers can be used to preserve ultra-dried seeds. However, foil bags than glass bottles light, small size, easy to seal. Therefore, when conditions permit, it is advisable to use silicone and foil pouches as the desiccant for desiccating seeds and containers
