蘭花地生

❶ 蘭花一般生長在什麼環境下

蘭花根據根系分為地生蘭和氣生蘭2大類，氣生蘭也叫洋蘭，生長在熱帶雨林地區，其裸露的根系可以直接從潮濕的空氣中吸收水份：地生蘭也叫中國蘭，分布在中國南方地區，其中以浙川雲地區為最，生長環境多以山澗處為主。

❷ 舉例地生蘭和氣生蘭的不同生長環境要求

附生蘭就是氣生蘭
原則上人們把蘭花分為地生蘭和附生蘭兩類，室內蘭花多屬後者。
附生蘭
熱帶地區的附生蘭，因為地面上缺乏日照才導致這類植物不得不攀附樹木或灌木生長，只有利用這種方式才能適應其生存環境的空氣條件。它們不僅生有可以固定植株的氣生根，還生有貯存營養和水分的肉質莖。但這些植物並非寄生植物。
房間中的原始森林
這些植物怎樣才能在我們這里存活？最簡單的辦法是：把它們當作房間里的附生植物對待。即將其植於木框或塑料穿孔盆中，中間插上樹枝或木桿，將附生蘭沿木桿向上捆紮。當然，還需注意使空氣、陽光空氣濕及室溫與熱帶環境相符。如有必要可在花房或玻璃棚溫室中栽培。
關鍵因素：培養土
不論是置於窗檯還是溫室之中的盆栽蘭花都可利用培養土人工營造附生的環境。這種情況下，蘭花對培養土的要求相當高。土質疏鬆且富含空氣。蘭根需要透氣良好的環境．故培養土不可壓實。除了通風良好之外．使用含鹽分少的軟水澆花同樣十分重要。
蘭花的休眠期
生有假鱗莖的蘭花(多數附生蘭如此)需要一段休眠期。休眠期內蘭花因不利的生長條件幾乎完全停止生長。休眠期與季節無關，有些蘭花的休眠期長達5個月之久，有的則只有3～4周。休眠期之後蘭花開始生長新芽．也就是說．開始下一個生長周期．．
地生蘭
最初蘭花皆生於地面植根於土中。只是由於缺乏日照及生長速度較慢才不得不逐漸適應了更高處的環境。地生蘭雖生乾地面但也偏愛林中或草地里富含腐殖質的疏鬆土壤．，熱帶地生蘭中最具代表性的當然是兜蘭（Paphiopedilum）與大花惠蘭（Cymbidium）但這兩個蘭種中並非所有蘭花均為地生蘭。生於地中海地區的蘭花及許多山地蘭花都屬地生蘭。
地生蘭易吸收到水分，一般擁有持續的養分供給。但它們也需要休眠期。尤其是生有新塊莖的蘭花需要相當長的休眠期。其他的蘭種．如熱帶兜蘭．則在輕微降溫或降水減少時即可進入休眠期。
與附生蘭相比地生蘭的根系在土中得到更好的保護。不利的環境條件如風、烈日和乾燥對它的危害相對較少因此其根系可向四周發展。因地生蘭的生存條件較附生蘭為優故其抗惡劣環境的能力總的來說遜於附生蘭。
地生蘭的養護
地生蘭的培養土不可干透，亦不可太濕。可視其生長情況施肥。移栽時需去除腐根及傷根。蘭花的熱帶故鄉雖然全年氣候均衡．但許蘭花多蘭花卻產於四季分明的地區，與此相適應的是它們具有特別長的休眠期，在冬季或乾燥季節葉片脫落或完全停止生長。除此之外，地生蘭與附生蘭對環境的要求幾乎沒有區別，只是在換盆移栽時地生蘭需要較細的培養土。
西藏虎頭蘭（Cymbidium tracyanum）生於緬甸高原地區，屬地生蘭。冬季可栽植於日照充分而涼爽的房間內。夏季可直接栽植於花園內。

❸ 蘭花生長在什麼地方

蘭花又名蘭草，是蘭科蘭屬多年宿根草本植物。

蘭花是我國傳統栽培觀賞的花卉，被譽為「天下第一香」。庭園、廳堂、幾案、書桌陳設蘭花，清幽芳香，格外清雅別致。

蘭科植物是植物世界中種類最多、分布最廣的一個大家庭，從溫帶、亞熱帶到熱帶雨林區域都可看到它們的蹤影。

蘭科植物基本上分為兩類：地生蘭和氣生蘭。全世界的蘭科植物有450屬17000多種，中國的蘭科植物的148屬1000多種，僅雲南就佔了100餘屬530種，全省遍布。

在中國古代藝術中，把它與竹、菊、梅並稱為「花中四君子」，引喻了一個人不被世俗污染的高潔品格。如屈原《九歌》中的「春蘭兮秋菊，長無絕兮終古」。

蘭花是著名的雲南八大名花之一。蘭科植物在全世界約四百五十屬一萬七千多種，其中可栽培的約二千種。中國的蘭科植物約一百四十八屬一千零八十種。蘭屬共七十種，分為氣生蘭和地生蘭兩大類。氣生蘭原產於熱帶、亞熱帶，附生於樹乾和岩石上。地生蘭原產於溫帶，一般供栽培觀賞，主要分布在中國，所以也稱中國蘭花。雲南是地生蘭的一個主要產區，資源豐富，品種繁多，達三十多種，主要栽培品種有春蘭、九節蘭、蜜蜂蘭、墨蘭、虎頭蘭、劍蘭等。在滇西的高黎貢山。蘭花長滿山谷，構成奇麗的景觀，花色紅、黃、白、綠，悅人耳目，花香情的飄逸，沁人肺腑。置身其境，對古人贊譽蘭花為「空谷佳人」，倍覺貼切。

❹ 蘭花的生長環境

蘭性喜陰，怕陽光直射，喜濕潤，忌乾燥，喜肥沃、富含大量腐殖質、宜空氣流通的環境。各地的氣候、環境、都能影響蘭花的生長，所以選擇植料的方式不同。例如福建閩南一帶，四季天氣較暖和，不會太冷，蘭花生長速度快，適合用小鵝卵石種植，第一、節省資源；第二、鵝卵石利於通風、不積水。

蘭花養殖技術：
場地選擇：要求四周空曠，通風良好，並靠近水面，空氣濕潤，無煤煙污染。場地的西南面，可種常綠闊葉樹，郁閉度應在0.7左右，這樣可減少午後陽光照射，調節濕度與溫度。
澆水：以雨水或泉水為宜，不宜用含鹽鹼的水，如用自來水，應將水擱置數天後使用。澆水要看氣溫情況而定，春季澆水量宜少，夏季宜多；梅雨季節正值蘭花抽生葉芽，盆土宜稍干；秋後天氣轉涼，澆水量酌減，保持濕潤即可。冬季在室內宜干，減少澆水次數，且宜於中午時澆。蘭花可淋小雨，但連續下雨或暴雨則易爛心、爛葉，故須注意防雨。
施肥：栽蘭宜用餅肥，以草木灰4份、豆餅10份、骨粉10份混合拌勻，放於缸內，分幾次加水，使豆餅浸漲為止，後加蓋密封，經一年腐熟，再製成干粒。使用時放於盆面即可。如用全糞，也應經一年腐熟，摻水沖淡濾渣使用。一般從5月開始施肥，至立秋停肥，掌握薄肥多施。施肥應在傍晚進行，第二天清晨再澆1次清水。
遮陽及防寒：除早春及冬季外，都要放在露天棚下。蔭棚要求通風良好，蘭花在3～4月間剛出房時，可以多曬太陽，以後蔽蔭時間漸增。冬季蘭花須搬入室內防寒，室溫保持1～2℃即可。另外，蘭花在春季出房後，秋季進房前，也要注意防霜。

❺ 簡述地生蘭和附生蘭的區別

這是根據蘭花在自然界的生活類型來區分的。地生蘭是指生於地面土壤之中的蘭花，如春蘭、蕙蘭、寒蘭和大部分兜蘭等；而附生蘭是指植株附著於某種寄主，如樹枝、樹干、岩石等上面，但僅僅是附著於寄主的表面，並不吸收其體內的養分的蘭花，在我國港台地區又稱作為著生蘭、氣生蘭。許多洋蘭都是附生蘭，如卡特蘭、萬代蘭等。從進化角度看，附生更是對環境的一種適應。但是在自然界中，地生蘭大多生長在多石、腐殖質豐富、排水良好的地面上，與有些植物相比，多少也有一點附生的習性。有些蘭花既能地生，也能附生，如兔耳蘭、台蘭。而有些附生蘭種在土中也能生長發育良好，從這個意義上看兩者也並沒有明顯的界限。此外，還有一種腐生蘭，它一般無葉綠素，是靠與真菌共生而吸取養分的，如著名的葯材天麻。

❻ 蘭花原產地在那裡

蘭科植物是被子植物五大科之一，種類極多，分布地域也很廣，僅在我國，就包括江浙、兩湖、河南、安徽、福建、兩廣、台灣、雲南、貴州、四川、重慶、貴州、江西等省、市、區。

❽ 蘭花的生長習性

Wax light can be used to distinguish the green leaves and correct the extraordinary appearance of the crown of many English. A new sprout, round bean, from Zhijia to Fengming - learn a little every day, make a little progress every day!
If you want to ask what animal is the most intelligent, the answer should be human, because human beings know that things are for me. So what's the smartest plant? If you look at it from the perspective of using things for me, there's no doubt that orchids are the smartest plants in the world. During the process of seed germination, growth and flowering and fruiting, orchids need to use other organisms to help complete the life cycle of orchids.

Orchid seed has its own distinctive characteristics in plants, mainly in the following aspects.
First, the number is huge and uneven. One capsule of orchid (commonly known as POD) can have up to 4 million seeds, but the minimum is only 20-50 seeds, with a difference of 80000-200000 times.
Second, the seeds are very small. The seeds are generally 0.05-6 mm long and 0.01 to 0.9 mm wide (the diameter of a hair is generally 0.08 mm).
3. The seed structure is simple. The outer testa of orchid seeds accounts for most of them, but the embryo is very small. Generally, the size of embryo is only about 1110 of the seed size. The smallest embryo is 0.1 mm long and only 0.078 mm wide (equivalent to the diameter of a hair). The embryo of orchid seed has no cotyledon or endosperm, that is to say, the mother plant of orchid does not provide any substance to help its offspring (seed) germinate and grow early.
4. There are many air filled cavities in the outer seed coat of orchid seeds, so the orchid seeds are very light. The heaviest orchid seeds are only 14-17 centigrams (1 centigram is equal to 1 / 100 grams), and the lightest ones are only 0.3-0.4 centigrams. Such a light seed can float far away from the mother plant with the help of wind and settle down. At the same time, there is a layer of closely arranged cells on the surface of the seed coat of orchid, so that the water is not easy to penetrate into the seed quickly, so that the orchid seed can float on the water surface and float for a long distance. Of course, orchid seeds can also be spread by animals, such as adhering to animal fur or claws covered with mud, or feathers of birds. They can also be spread by animal feeding, and even by human activities. For example, a kind of fire orchid distributed in North America was spread from Europe to North America through human activities. The plants of Cymbidium spp. can only be seen on the surface of the earth, such as the plants of Orchidaceae, which are very high in calcium content, and can not be seen on the surface of the earth. We found more than 30 kinds of terrestrial orchids in a gully about 2.5 km long and 0.5 km wide in Huanglong scenic area of Sichuan Province, and tens of thousands of orchids grew together. Huanglonggou is a tuffaceous gully that graally rises from south to north. It is the unique travertine in the gully that provides suitable habitat for the growth of orchids and forms a completely different vegetation type with orchids as the main body from the adjacent gullies. Orchid seeds do not have any stored nutrients to help them germinate and grow. When orchid seeds germinate and grow together with the seeds of other plants with cotyledons or endosperm in the same lifetime, it is obvious that orchid seeds belong to the "vulnerable group", and their germination and seedling growth after germination cannot compete with other plants, because plants with cotyledons or endosperm germinate in seeds The stage and seedling stage can survive this critical and difficult period with the help of nutrients stored in cotyledons or endosperm. This is the main reason why orchids always grow in special habitats where other plants are difficult to grow. So how does orchid seed germinate and grow in these special habitats? The secret is that orchid seeds use fungi to help it absorb nutrients and water ring germination and growth. It has been found that orchid seeds must be assisted by fungi when they germinate under natural conditions. Some orchid species need fungi to help them absorb nutrients and water ring the whole development process from seed germination to seedling, growth and mature plants, which is the case for saprophytic orchids without chlorophyll. If there is an orchid in Australia that grows under the earth's surface all its life, there must be fungi to help it absorb nutrients and complete its life cycle. Even some species need different kinds of fungi to help at different stages of growth and development. The most typical example is Gastrodia elata, a famous medicinal plant. Through nearly 30 years of research, Chinese scientists first found that Gastrodia elata seeds need to use fungi called small mushrooms to help them obtain nutrition and germinate. After the germinated seedlings (protocorms) grow other propagation bulbs, they need to cooperate with a fungus called Armillaria mellea to help them grow and develop. Some orchid species do not need the help of fungi after the seedling growth stage, but fungi still exist in the roots and even stems of these orchids. Some of these fungi are beneficial to the orchid, while others are not. Therefore, in the critical and difficult period of germination and seedling growth, tiny orchid seeds skillfully rely on the help of fungi to survive in places where other plants are difficult to survive.

In the process from seed to seedling, orchid adopts a strategy of wide planting and thin harvest, which proces a large number of seeds, but only a few seeds can germinate, grow and finally grow into mature plants. However, in the process from flowering to fruiting, a completely different strategy was adopted. orchid

❾ 蘭花主要生長在哪些地方

蘭大部分品種都原產於中國，因此又世人稱為中國蘭，並列為中國十大名花之首。專中國屬蘭花主要為春蘭、蕙蘭、建蘭、寒蘭、墨蘭五大類，有上千種園藝品種。在第10屆亞太蘭花大會在中國重慶開幕。此間，一株名為「素冠荷鼎」的蓮瓣蘭估價1500萬人民幣，成為此次蘭花大會上的「天價」蘭花。此次蘭花大會共評出兩個特別金獎，分別是：由日本名古屋國際蘭花大會組委會永田治彥選送的微中子碧玉蘭「龍袍」，和由中國雲南大理盪山州選送的蓮瓣蘭「素冠荷鼎」。據介紹，獲獎的蓮瓣蘭「素冠荷鼎」是中國雲南大理盪山州蘭園的鎮園之寶，有人曾出1200萬未能購走，該蘭花估價1500萬人民幣。蓮瓣蘭「素冠荷鼎」姿態非常優美。
