在地下沉睡了千年的古莲怎么还会开花呢?
How can ancient lotus blossom after sleeping for thousands of years?
这与莲子的结构有关。莲子的外种皮坚硬致密,像个小小“密封包”,把种子密闭在里面,可防止外面的水分和空气的渗入,也可以防止种子内的水分和空气散失,因此莲子的生命活动极为微弱,相当于休眠状态。这是古莲子还有生命力的重要原因。
This is related to the structure of lotus seeds. The outer seed coat of lotus seed is hard and dense, like a small "sealed package". The seeds are sealed inside, which can prevent the infiltration of water and air outside, and also prevent the loss of water and air inside the seeds. Therefore, the life activity of lotus seed is extremely weak, which is equivalent to the dormancy state. This is an important reason for the vitality of ancient lotus seeds.
此外,与古莲子所埋藏的环境也有关。这些古莲子是被埋在深约30-60厘米的泥炭层中,而泥炭的吸水防潮性能良好;再加上泥炭层的上面又有很厚的泥土覆盖,因此古莲子几乎处于一个密闭的环境中。在这样的环境中,古莲子不具有生根发芽的条件,因此而得以保存了生命力。
In addition, it is also related to the burial environment of ancient lotus seeds. These ancient lotus seeds are buried in a peat layer about 30-60 cm deep, and the peat has good water absorption and moisture-proof performance; in addition, the peat layer is covered with a thick soil, so the ancient lotus seeds are almost in a closed environment. In such an environment, the ancient lotus seeds do not have the conditions for rooting and germination, so they can preserve their vitality.
