Miscanthus is a genus within the family of the Poaceae (Gramineae), which depending on the source 14-20 species comprises. The genus predominantly thrives in wet meadows and swamps from Africa to East Asia , in particular a number of species can be found in China and Japan . While the Chinese reed ( Miscanthus sinensis ) is mainly used as an ornamental plant, the giant Chinese reed ( Miscanthus × giganteus ) is an important energy plant .
description
The species of the genus are perennial , deciduous or evergreen , tufted or rhizome-forming grasses. The reed-like shoots have linear or narrowly lanceolate, folded, overhanging leaves that can be light or medium green or blue to purple-green in color.
The genus Miscanthus can easily be recognized by its inflorescence. The inflorescences consist of dense, terminally arranged, overhanging panicles , which are formed from the paired and basal long silky hairy spikelets . The inflorescences appear in late summer and autumn and after long, hot summers they produce more flowers.
Systematics
The genus Miscanthus was established in 1855 by Nils Johan Andersson . The generic name Miscanthus is derived from the Greek words mískos for "stamp, stem" and τὸ ἂνθος to ánthos for "the flower", "the blossom" and the like. a. derived. Synonyms for Miscanthus Andersson are: Diandranthus Liou nom. inval., Miscanthidium Stapf , Sclerostachya (Hack.) A.Camus , Tiarrhena (Maxim.) Nakai orth. var., Triarrhena (Maxim.) Nakai , Xiphagrostis Coville .
There are about 14 types:
- Miscanthus changii Y.N. Lee : It occurs in Korea.
- Miscanthus depauperatus Merr. : It occurs in the Philippines.
- Miscanthus ecklonii ( Nees) Mabb. (Syn .: Miscanthus capensis ( Nees ) Andersson ): The home is tropical and southern Africa.
- Miscanthus floridulus (Labill.) Warb. ex K.Schum. & Lauterb. : The distribution area extends from Indochina to Japan and to the islands in the Pacific.
- Miscanthus fuscus (Roxb.) Benth. : It occurs from the Indian subcontinent to the Malay Peninsula .
- Miscanthus junceus (Stapf) Pilg. : It occurs from southern tropical Africa to southern Africa.
- Miscanthus lutarioriparius L.Liu ex SLChen & Renvoize : It occurs in the Chinese provinces of Hubei and Hunan.
- Miscanthus nepalensis (Trin.) Hack. : The distribution area extends from India to China and Malaysia.
- Miscanthus nudipes (Griseb.) Hack. : It occurs in two subspecies from Nepal to southern and central China.
- Giant Chinese reed ( Miscanthus × ogiformis Honda , Syn .: Miscanthus × giganteus J.M. Greef & Deuter ex Hodk. & Renvoize = Miscanthus sacchariflorus × Miscanthus sinensis ): It occurs in Korea and Japan.
- Miscanthus oligostachyus Stapf : Home is Korea and Japan.
- Miscanthus paniculatus (BSSun) Renvoize & SLChen : It thrives on dry mountain slopes at altitudes of 2500 to 3100 meters in the Chinese provinces of Sichuan, Yunnan and western Guizhou.
- Miscanthus sacchariflorus (Maxim.) Hack. : The range extends from Japan and eastern China to the far east of Asia.
- Chinese reed ( Miscanthus sinensis Andersson , Syn .: Miscanthus purpurascens Nees , Miscanthus transmorrisonensis ( Hayata ) Andersson ): The distribution area extends from Malesia and China to the far east of Asia.
- Miscanthus tinctorius (Steud.) Hack. : The home is Japan.
- Miscanthus villosus Y.C.Liu & H.Peng : It occurs in Yunnan .
- Miscanthus violaceus (K.Schum.) Pilg. : It occurs from Uganda to Zambia.
use
The fast-growing hybrid Miscanthus × giganteus (from M. sacchariflorus and M. sinensis ), also known as giant Chinese reed, offers favorable conditions for use as a renewable supplier of biomass , fuel, building material or litter in animal husbandry due to its high calorific value and its favorable carbon dioxide balance.
The calorific value roughly corresponds to that of wood. The reason that Miscanthus has not been used industrially so far (2015) is that thermal power stations would have to be converted for it. Miscanthus makes a lot of ash. In Hoffenheim in Baden-Wuerttemberg there is a thermal power station that is only operated with Miscanthus . The delivery of the material by regional growers ensures short distances.
Plant protection products (except in the first year) and mineral fertilizers may not be used on an area with miscanthus, which is designated as an area used in the environmental interest ( Section 32b of the Direct Payments Implementing Ordinance).
As ornamental plants, Miscanthus species are planted as solitary plants or in mixed and herb borders. Chinese reed is also suitable for planting the edges of water and as a privacy screen for the summer time. The inflorescences can be harvested as cut flowers. The Miscanthus species used are fully frost hardy to frost hardy and tolerate almost all cultivation conditions.
