The inner wall of the plant's conduit will be especially thickened in certain parts, forming various textures, some of which are annular, some are trapezoid, some are net shaped. However, the thickened part of the wall of the lotus root's conduit is continuously spiral, which is specially called spiral conduit. When the lotus root is broken, the thickened spiral part of the inner wall of the conduit breaks away and becomes a spiral filament with a diameter of only 3-5 microns. These filaments are very similar to the stretched spring. They will not be broken within the elastic limit. They can be stretched to about 10 cm in general.
藕丝不仅存在于藕内,在荷梗、莲蓬中都有,不过更纤细罢了。如果你采来一根荷梗,尽可能把它折成一段一段的,提起来就像一长串连接着的小绿“灯笼”,连接这些小绿“灯笼”的,便是这种细丝。这种细丝看上去是一根,如放在显微镜下观察,会发现其实是由3~8根更细的丝组成,宛如一条棉纱是由无数棉纤维组成一样。
Lotus root silk not only exists in lotus root, but also in Lotus stem and lotus canopy, but it's more slender. If you pick a lotus stem, fold it into sections as much as possible, and lift it up like a long string of small green "lanterns", which are connected by this kind of filaments. This kind of filament looks like one. If it is observed under a microscope, it will be found that it is actually composed of 3-8 finer filaments, just like a cotton yarn is composed of countless cotton fibers.
