Guadua – Wikipedia

The minimum straightness or curvature that they present is totally assured because although in the plantation always some can appear with curves, our canes are perfectly straight angustiifolia to a careful selection in origin the pieces of this variety are not straightened with heat as it is done in China.

Under this method, culms are cut at ground level when harvesting causing many small shoots and new plants to grow around the original plant. Environmentally, Guadua is more effective at removing carbon dioxide from the atmosphere than most other tropical forest [ citation needed ] ; ongoing studies in Colombia have now been coordinated by the Environmental Bamboo Foundation.

To prevent the bamboo from being attacked by xylophagous insects angystifolia to prevent fungal growth, the canes are immersed for days in a solution of borax and boric acid at a ratio of 1: If it is necessary to hide these anguxtifolia, either for aesthetic reasons or to facilitate the cleaning of the structure itself, the ideal is to cover them with the same flexible putties used in wood, since it is usual that with an increase in humidity kjnth openings close again.

For structural applications of Bamboo, whenever possible it is preferable to prevent the sun from shining directly on the canes by protecting the structure by design, including eaves in the project and not leaving the ends exposed. Since bamboo is a grass, harvesting it down to the soil induces more new shoots guaeua emerge, just like turf grass. There is a great amount of life inside, with a multitude of plants, mammals, birds and reptiles associated with them.

They usually grow at low altitudes below 1, mbut has been found up to 2, m.

Retrieved 10 December In addition, regular and controlled exploitation favours the development of Guadual as a whole and stimulates its natural regeneration. During the first 6 months they grow at a very high rate, which can reach 15 cm per day until reaching their final height of 20 to 30 m.

On the basis of such studies, Japan and the Netherlands have both undertaken massive forestation projects as a kuhth of earning so-called “carbon uknth to offset industrial pollution [ citation needed ].

It is common for some cracks to appear in the bamboo, always longitudinal, which do not pose any structural problem as the properties of bamboo remain practically unchanged. Another important protection to take into account is to avoid direct contact with sources of moisture because, although the Guadua includes a complete treatment against fungi and xylophages, the great variations of humidity inside can end up producing cracks. Its diameter is constant for the first 15 uknth and then tapers at the top.

Manual de Plantas de Costa Rica. Missouri Botanical Garden, St. From a utilitarian perspective, Guadua is the most important American bamboo.

The wall thickness is generally quite thick, although it can vary between the different sections chosen. Protection by Design and Maintenance When building with bamboo on the outside as with any timber it is necessary to take into account the action of the sun on the surface of the reeds. Guadua angustifolia [1] [2] Kunth. Properties Among the characteristics of the Guadua is its extraordinary firmness to compression and a good resistance to the parallel cut, this added to the great flexibility that presents turn the Guadua cane into a tool especially interesting for the bioconstruction, where this catalogued as structural material seismic-resistant.

For architectural purposes, Guadua is the preferred bamboo species. This method is suitable for large-scale forests or farm cooperatives. The bamboo does not increase its diameter with the passage of time, but emerges from the soil with its diameter determined, being a monocotyledonous it lacks cambium tissue so it does not get fat like trees….

After about 4 years the stem is considered to have the ideal maturity for use as a structural material and is cut.

Recent earthquakes in Colombia’s coffee zone demonstrated this when many houses built in the s survived, while modern houses collapsed [ citation needed ].

The plant and its origin This variety was initially identified as guavua to the Bambusas until when the German botanist Karl S. Harvesting can begin six years after planting, making bamboo a potential source of tropical biomass production for industry e.

This page was last edited on 10 Novemberat If this is done well, a rhizomatic energy transfer mechanism begins in the plant and a new culmo begins to be generated, so that new production is guaranteed.

Journal of the American Bamboo Society 18 1: Or, Guadua can be propagated more rapidly by the chusquin method. The preservation by Immersion in Pentaborate is considered friendly because its functionality does not depend on a toxic but on salts, a natural and innocuous product at these concentrations.

In the vines can reach more than 3 cm, used in pillars or where a lot of work is received by compression while in the bases can be kuntth 0.
