After a spring rain, I made a careful observation, "poplar Hu" in the rain after that refreshing moist air in the land. Why is that? Is it coincidence or is there some scientific reason?
原来“白杨胡不落干地”有两个原因:第一“白杨胡”就是白杨树的种子,不过它的种子又轻又小,就藏在毛茸茸、蓬松松的“胡”里。因为种子既小又轻,不象别的植物种子成熟以后有一定的重量,能自然地落在地上。第二,春雨过后毛茸茸、蓬松松的“胡”吸足了水分,重量增加了许多,再加上雨后的春风一吹,“白杨胡”便洒落了一地。这种有趣的自然现象年复一年地出现,难怪有经验的老农说:“白杨胡不落干地”了。
There are two reasons for the original "Bupleurum does not fall on the dry land": the first "Bupleurum" is the seed of the poplar tree, but its seed is light and small, which is hidden in the fluffy and fluffy "Hu". Because the seeds are small and light, they do not have a certain weight after ripening like other plant seeds, and can fall on the ground naturally. Second, after the spring rain, the fluffy and fluffy "Hu" absorbed enough water, and its weight increased a lot. In addition, when the spring wind blew after the rain, the "poplar Hu" was scattered all over the ground. This kind of interesting natural phenomenon appears year after year. It's no wonder that the experienced old farmer said, "poplar and Hu can't leave the dry land".
