例句

Wei dug up the gladiolus corms in autumn to store them for winter.

偉在秋天挖起劍蘭的球莖，以便冬季儲藏。

phrasal collocation: dig up [plant] corms

Unlike tulip bulbs, a corm has a solid, fleshy interior with no visible layers.

與鬱金香的鱗莖不同，球莖內部是實心的肉質，沒有明顯的層次。

comparison: corm vs bulb — solid vs layered

同義詞
  • bulb

    commonly confused but botanically distinct — bulb has layers; corm is solid

  • tuber

    a different storage organ — tubers (e.g. potatoes) are enlarged stem tips, not stem bases

用法筆記

Distinguish from bulb: a bulb (like an onion or tulip) has layers of fleshy leaves, whereas a corm is a solid, non-layered stem. Crocuses, gladioli, and taros grow from corms, not bulbs.
