为什么大蒜和洋葱必须晒干后种在地里？
水是生命之源，没有水就不会有生命存在，这是一个普通的道理。大蒜和洋葱经过太阳晒干后种在地里还可以长苗，你知道这是什么原因吗?
大蒜头和洋葱头都不属于种子类，它们属于物体地下变态茎，在生产上能够直接用于繁殖，一般需要晒干保存。生物体内的水分一般有两种状况，一部分水可以自由流动，叫自由水，另一部分水跟其它物质结合，难以自由流动，叫结合水。我们所说保存时的晒干，只是使它失去了可以自由流动的那部分水，这样不仅有利于保存，而且跟其它物质结合的那部分水不容易晒干。因此大蒜和洋葱晒干后种在地里还能长苗，就是这个道理。
人们在生活中常食用大蒜和洋葱，是由于它们含有很多的植物杀菌素，因此具有治病和防病的医疗效果。平常我们只要把大蒜和洋葱放在嘴里咀嚼3分钟，就能消灭口腔细菌。因为它们含有植物杀菌素，所以很少发生病害。
