Lewandowski I, Scurlock JMO, Lindvall E, Christou M. 2003. Carbon dioxide exchange is regulated by leaf conductance.[9]. However, in the last decades, the rural migration from the countryside to urban centres and the extensive exploitation of land has substituted traditional crops. CDFW is temporarily closing its high public use areas, including visitor centers and license counters, to help slow the spread of COVID-19 (coronavirus). 2004). Prev: The growing need for NON-WOOD PELLETS, Next: 5 Tips for Arundo Donax Removal: How to Get Rid of Giant Reed. It is among the fastest-growing terrestrial plants in the world (nearly 10 centimetres (3.9 in) / day; Dudley, 2000). [7] Instead, it mostly reproduces vegetatively by tough, fibrous underground rhizomes that form knotty, spreading mats which penetrate deep into the soil, up to 1 metre (3.3 ft) deep (Alden et al., 1998; Mackenzie, 2004). Rich in fibre, crude protein content of about 11-21%, Arundo silage is as digestible as maize silage – just to name a few of its values. [32] An excavator can be useful to dig out the rhizomes or alternatively a single late-season application of 3% glyphosate onto the foliar mass is efficient and effective with least hazardous to biota. If you are interested in more facts on bioethanol gained from Arundo Donax, click here! Furthermore, Arundo Donax can stored in bales of 600-800 kg which reduces logistic costs. Using biogas in general has a cleaner impact on the environment, since biogas is a carbon neutral fuel. Check label for specific water use restrictions. In the Mediterranean, where a temperate climate is characterized by warm and dry summer and mild winter, new shoots of giant reed emerge around March, growing rapidly in June and July and producing stems and leaves. The grey-green swordlike leaves are alternate, 30 to 60 centimetres (12 to 24 in) long and 2 to 6 centimetres (0.79 to 2.36 in) wide with a tapered tip, and have a hairy tuft at the base. Whilst you can use Arundo alone to source your biogas refinery, it is a complimentary ingredient for a mix with other organic waste in the anaerobic digester. Interestingly enough, the prayer flag poles used by the Huichol in their peyote ceremonies are made from A. donax reeds, as well as the shafts of the arrows used in the peyote hunt. It has a high photosynthetic capacity, associated with absence of light saturation. Grazing animals such as cattle, sheep, and goats may have some effect on it, but are unlikely to be useful in keeping it under control (Dudley 2000). [34] Outside its native range, this needs to be balanced against its major invasive potential. Giant reed has the possibility of adopting low plant density. [citation needed] Its stiff stems are also used as support for climbing plants or for vines. Perennial rhizomatous grasses display several positive attributes as energy crops because of their high productivity, low (no) demand for nutrient inputs consequent to the recycling of nutrients by their rhizomes, exceptional soil car… As the impact of Arundo donax increased in the environment and native species various efforts have been taken to reduce its population. Arundo donax (giant reed). Read further to find out more about Arundo Donax uses! [14] The same study determined that accumulations of As, Cd and Pb were high in roots but low in shoots, where SEM images showed thick and homogeneous stem tissue characteristics. Giant reed is native to warm temperate and subtropical areas of Asia. [19] Despite its invasive characteristics in regions around the world where it is not native, Arundo is being promoted by the energy industry as a bio-fuel crop. Crowds out native plants species; reduces wildlife habitat; contributes to higher fire frequency and intensity; and modifies river hydrology (. Dried biomass has a direct combustion high heating value of 3,400 kJ/kg (8,000 BTU/lb). Arundo donax generally grows to 6 metres (20 ft) in height, or in ideal conditions can exceed 10 metres (33 ft). 1993. When young, A. donax is readily browsed by ruminants, but it becomes unpalatable when maturing. It had been used to make primitive pipe organs. Recently, initiatives are being taken to recover the use of this material, combining ancient techniques from southern Iraq mudhif (reed houses) with new materials. A. donax is still the principal source material of reed makers for clarinets, saxophones, oboes, bassoons, bagpipes, and other woodwind instruments. Its low weight, flexibility, good adherence of the cañizo fabric and low price of the raw material have been the main reasons that made this technique possible to our days. University of California, Santa Barbara. Several field studies have highlighted the beneficial effect of giant reed crop on the environment due to its minimal soil tillage, fertilizer and pesticide needs. Several reports underlined that it is more economical to grow giant reed under moderate irrigation. Giant reed, (Arundo donax), also called arundo or giant cane, tall perennial grass of the family Poaceae. [30] In this field study, it was noticed how the lowest density (12 500 rhizomes ha−1) resulted in taller and thicker plants compared to denser plantation (25 000 rhizomes ha−1). Due to its high growth rate and superior resource-capture capacity (light, water and nutrients), A. donax is not affected by weed competition from the second year. Comparative embryology of some grasses. There are more and more furniture producing companies going green: IKEA is the leading firm, by aiming to be planet positive by 2030. Regarding the humification parameters, there were noticed any statistically differences between giant reed and a cropping sequence (cereals-legumes cultivated conventionally). Need more convincing information? This may lead to decreased oxygen concentrations and lower diversity of aquatic animals (Bell 1997). Cultivation Options. What is more, you don’t need to invest into new technologies since the plant is processed using similar methods to wood based pellets and briquettes. In comparison to the commonly used Mischantus, Arundo has a higher biomass yield, more adaptable to a broader range of soils and better withstands drought and moisture stresses. In rural regions of Spain, for centuries there has existed a technique named cañizo, consisting of rectangles of approximately 2 by 1 meters of woven reeds to which clay or plaster could be added. [11] This sterility, which drastically limits genetic variability, is an obstacle for breeding programs which aim to increase the productivity and biomass quality for energy conversion. It is one of several so-called reed species. As a by-product, the use of this plant also reduces erosion. studies justified that Arundo Donax produces 50% more ethanol than sugar cane or sugar beet, and 20% more than Miscanthus. Most infestations of giant reed must be controlled with chemical treatment. In order to ensure good root stand and adequate contact with the soil, sufficient moisture is needed immediately after planting. [42] A. donax has also been used in constructed wetlands for wastewater treatment.[43]. Riffaldi, R., Saviozzi, A., Cardelli, A., Bulleri, F., and Angelini, L. 2010. Mariani C., R. Cabrini, A. Danin, P. Piffanelli, A. Fricano, S. Gomarasca, M. Dicandilo, F. Grassi and C. Soave. The flat leaves are often 60 cm (2 feet) long and about 7.5 cm (3 inches) wide and are borne alternately on thick canelike stems. Apart from saving forests, another environmental benefit is that Arundo Donax requires 2/3 of the adhesive material compared to wood – imagine the money saved! A. donax will produce an average of three kilograms of biomass per square metre (25 tons per acre)[clarification needed] once established. In order for mechanical treatment to be effective, an infestation must be caught very early, when plants are new and shorter than two meters. The base growth temperature reported for giant reed is 7 °C,[8] with a maximum temperature of 30 °C. Giant reed is 1.8 to 7 metres (about 6 to 23 feet) tall and grows in dense clumps. Center for Invasive Species Research. Our editors will review what you’ve submitted and determine whether to revise the article. In online book: Bossard, C.C., J.M. The feathery flowers, borne in plumes up to 60 cm (2 feet) long, are usually seedless or sterile. Origin, diffusion and reproduction of the giant reed (Arundo donax L.): a promising weedy energy crop. We make tools for color correction, compositing, editing, stylizing, transitions, and text.
