教室裡的仙人掌幼苗_銀冠玉

第2週防疫居家學習課表首頁圖片簡介

還記得2020/9/18播種、發芽至今8個月的仙人掌幼苗嗎？(自然課植物單元)

它們一直栽培在教室窗台，現在長成的樣子如圖1

銀冠玉的故鄉在南美洲，墨西哥中部的荒漠，原產地侷限在一個高地區域。以下看到的銀冠玉都是日本園藝家培育的後代，再進口輸入臺灣的，因此選拔出異於原生種特徵的個體。

銀冠玉成長緩慢，圖2可比較從1-2年到5-6年生長的樣子。

閱讀完以上介紹，請在留言處回答以下3個問題：

1.野生的銀冠玉比較大顆，可以採集進口種植欣賞嗎？理由是？

2.妳/你在教室裡偶爾觀察它們時，有發現過什麼現象嗎？

3.妳/你覺得臺灣的氣候適合栽培仙人掌嗎？猜猜看首頁上那顆結果實的銀冠玉已經幾歲了？

Lophophora fricii

This is the cactus seedling that we have sowed on 18/9/2020 and has been sprouting for 8 months.

They have been cultivated on the window sill of the classroom, and now they look like Figure 1

The hometown of the Loph  is in South America, the desert of central Mexico, and its origin is limited to a highland area. The Loph seen below are all descendants cultivated by Japanese horticulturists and then imported into Taiwan. Therefore, individuals with characteristics different from the original species are selected.

Lopho grows slowly, Figure 2 can compare the growth from 1-2 years to 5-6 years.

After reading the above introduction, please answer the following 3 questions in the message area:

1. The wild Loph is relatively large, can it be collected and planted for appreciation? The reason?

2. Have you ever noticed anything when observing them occasionally in the classroom?

3. Do you think the climate in Taiwan is suitable for growing cacti? Guess how old the fruity Loph on the homepage is?
