[:en]In the rainforest, there is a kind of plant that can be seen everywhere. It is tall and tall, and the leaves are slender. The whole plant looks like a peacock that is open to the screen, so it has a peacock tree.
This cultivation is the traveler’s banana, which was originally produced in Madagascar, Africa, and is the country’s national tree. Travelers’ bananas are also cultivated in Guangdong, Guangxi, Hainan, and Taiwan south of the Tropic of Cancer.
The traveler’s banana can reach up to 30 meters, which is taller than many trees, but it is a real herb.
The story of the traveler’s banana
The most amazing thing about Traveler’s banana is that it can provide a lot of sweet and sweet drinking water. For many people who are hungry and thirsty outdoors, it is definitely a life-saving grass.
I heard that a long time ago, there was a camel caravan in the inland of Africa. I walked in the desert of arid and hot days for a few days and nights, lost my way, the dry food was finished, and the water was exhausted. Just when they were in danger and ready to go, Suddenly found the bananas in the desert. They want to fold some leaves to feed the camels. Whoever thinks that a lot of water is flowing out of the blade breaks, so they are saved. What’s even more amazing is that at night, the wounds of the traveler’s bananas will heal actively, just like the faucet is closed. Fortunately, they thought that this cultivation was the ambulance god of the traveler, so it was called “the traveler banana”, and some people called it “water tree”.
The principle of water storage for tourists
The traveler’s banana leaf sheath can store rainwater. When it rains, the rainwater received by the huge blades flows into the petiole groove along the petiole, while the large, tightly placed petiole is seamless and seamless, so that the rainwater can only enter and the drip does not leak. In addition, the epidermis of the petiole itself and a layer of waxy skin powder can not only effectively avoid water transpiration, but also improve its drought resistance.[:zh]在雨林，有壹種隨處可見的植物，它樹形高大，葉片修長，全株好像開屏的孔雀般美麗，因而又得壹別名孔雀樹。
這栽培物就是旅人蕉，旅人蕉原產於非洲馬達加斯加，是該國的國樹。旅人蕉在我國北回歸線以南的兩廣、雲南、海南、臺灣等地也都有栽培。
旅人蕉最高可達30米，比很多喬木都要高大，但它卻是實打實的草本植物。
旅人蕉的故事
旅人蕉最神奇的地方在於它能夠提供很多清甜甘冽的飲用水，對很多戶外迷路饑渴難耐的人而言，絕對是救命草
聽說很久以前，在非洲內陸有壹只駱駝商隊，在幹旱酷熱的沙漠中行走了幾天幾夜，迷失了方向，幹糧吃完了，水也喝盡了，正當他們岌岌可危、束手待斃的時分，突然發現了沙漠中的旅人蕉。他們想折些葉片餵駱駝，誰想到在葉片折斷處流出很多的清水，於是他們得救了。更令人稱奇的是，到了晚上，旅人蕉的傷口便會主動愈合，就好像水龍頭關閉相同。幸虧之余，他們以為這栽培物是旅行者的救護神，故稱之為“旅人蕉”，亦有人形象地稱之為“水樹”。
旅人蕉儲水原理
旅人蕉葉鞘內能夠儲存雨水。下雨時，巨大的葉片接受的雨水順著葉柄流入葉柄槽內，而下部廣大、擺放嚴密的葉柄嚴絲無縫，使得雨水只進不出，滴水不漏。再加上葉柄自身潤滑的表皮和包被壹層蠟質皮粉，不只能有效地避免水分蒸騰，還能提高自身的抗旱能力。[:]
