芦苇Phragmites
芦苇(学名:Phragmites australis)是生长于沼泽、河摊、海滩等湿地的一种植物,遍布于全世界温带和热带地区,芦苇属的植物大约有10种,有的分类学家认为只有芦苇是芦苇属的唯一种。
Phragmites australis, the common reed, is a large perennial grass found in wetlands throughout temperate and tropical regions of the world. It is sometimes regarded as the sole species of the genus Phragmites, though some botanists divide Phragmites australis into three or four species and in particular the South Asian Khagra Reed (P. karka) is often treated as distinct.[2]
形态
芦苇是多年生草本植物,地下有匍匐的根茎,可以在适合的地区迅速地铺展繁殖,一年可以平铺延伸5米以上,地上茎高达2-6米,丛生,叶长达20-50厘米,排列成两行,圆锥花序,花穗长10-40厘米,每个小穗有4-7朵小花,属风媒花。美洲亚种植株比较矮小。
Growth
Common reed commonly forms extensive stands (known as reed beds), which may be as much as a square kilometer or more in extent. Where conditions are suitable it can spread at 5 metres (16 ft) or more per year by horizontal runners, which put down roots at regular intervals. It can grow in damp ground, in standing water (up to a meter or so deep), or even as a floating mat. The erect stems grow to 2–6 metres (6 ft 7 in–19 ft 8 in) tall, with the tallest plants growing in areas with hot summers and fertile growing conditions.
The leaves are long for a grass, 20–50 centimetres (7.9–20 in) and 2–3 centimetres (0.79–1.2 in) broad. The flowers are produced in late summer in a dense, dark purple panicle, about 20–50 cm long. Later the numerous long, narrow, sharp pointed spikelets appear greyer due to the growth of long, silky hairs.
Common reed requires neutral or alkaline water conditions, and so it does not usually occur where the water is acidic.[citation needed] It tolerates brackish water, and so is often found at the upper edges of estuaries and on other wetlands (such as grazing marsh) which are occasionally inundated by the sea.
Common reed is suppressed where it is grazed regularly by livestock. Under these conditions it either grows as small shoots within the grassland sward, or it disappears altogether.
用途
芦苇是保护湿地环境和野生动物的重要物种,许多种鸟类栖息在芦苇丛中。
芦苇杆含有纤维素,可以用来造纸和人造纤维。中国从古代就用芦苇编制“苇席”铺炕、盖房或搭建临时建筑。古代各国都有用芦苇中空的茎制造的乐器——芦笛,芦苇茎内的薄膜做笛子的笛膜使用。芦苇穗可以作扫帚,花絮可以充填枕头。芦苇的根是一种中药——芦根,入药性寒,味甘,功能清胃火、除肺热,主治热病烦渴、胃热呕吐、肺痈等症。
Uses
Thatching
Main article: Thatching
Reed is used in many areas for thatching roofs. In the British Isles, common reed used for this purpose is known as Norfolk reed or water reed. However "wheat reed" and "Devon reed", also used for thatching, are not in fact reed, but long-stemmed wheat straw.
Water treatment
Main article: Constructed wetland
Reed is the main wetland species used for water treatment.
Waste water from bathrooms, lavatories and kitchens is routed to an underground septic tank-like compartment where the solid waste is allowed to settle out. The water then trickles through a constructed wetland or artificial reed bed (not to be confused with the natural reed bed habitat), where bacterial action on the surface of roots and leaf litter removes some of the nutrients. The water is then suitable for irrigation or discharge to watercourses.
Other uses
Some other uses for reeds in various cultures include baskets, mats, pen tips, and a crude form of paper.
In the Philippines, Phragmites is known by the local name "tambo". Reed stands flower in December, and the blooms are harvested and bundled into brooms called "walis". Hence the common name of household brooms is "walis tambo".
