每日口說挑戰 為何香草那麼貴？(Why Vanilla Is So Expensive)

今日挑戰句子

Vanilla vines take two to four years to fully mature, and their flowers only bloom for one day of the year. In order for the plants to produce beans, they have to be pollinated that day. In most places where vanilla is grown, it isn't a native plant, and there aren't bugs or birds capable of pollinating the flowers.

香草藤需要兩到四年才能完全成熟，香草藤的花一年只開一天，為了使植物產生豆子，那天他們必須被授粉。在大多數香草種植的地方，它不是土生土長的植物，沒有蟲子或鳥類能夠為花授粉。
