密封罐中植物靠自养生长了40年

[attach]16221[/attach]


园丁David Latimer在53年前进行了一次植物实验。他将一些植物装进了瓶子里再也没拿出来，结果...
这位高龄80的园丁在1960年将4颗种子装进了一个巨大的罐子里。尽管他已经40年没浇水了，但其中的一株仍然长势喜人。最初，David只是为了证明植物可以在独立的环境中生存。他将容器密封后，四棵植物中的三棵死去了，但是剩下的这棵紫露草一直在生长。
David是名园丁，同时也是萨里郡的退休电气工程师，他说：[indent]
我从1960年就开始进行这个实验了，当时瓶子园艺很火。我想看看植物在独立的环境能否活下来。...这个实验是为了看看植物能活多久，今天有一棵活着。紫露草一直在长，现在它们几乎撑满了整个瓶子。我在1970年初浇了两次水。“
一些人并不知道这个实验的目的是什么，但事实上我没什么太特殊的目的，只是为了看看植物能活多久。
植物为了活下来，必须从日光中吸收太阳能，从它自己产生的水蒸气中获取水分，从落下的腐叶中获取二氧化碳和营养物质。它自身也会产生氧气。[/indent]
David为Radio 4的园艺百问时间节目拍了一张照片。
主持人Chris Beardshaw说：“这个绝佳的例子展示了植物所具备的极强的开拓性和耐久性。”
