This research investigates the basic density of Calamus manan cane grown in plantation and its relationship to strength. Cane samples were obtained from two plantation area in Malaysia. The results indicate that the lower part of the cane shows to have higher basic density compared to the higher part of the cane. The older canes (18 and 24 year-old) show a higher basic density compared to young canes (7 and 11 year-old). Samples with higher basic density show to have higher strength compared to those with lower basic density. Older canes indicate to have a 7-8-times higher strength compared to young canes.

Physical and mechanical properties of three rattan cane species, Calamus deerratus, Eremospatha macrocarpa and Laccosperma secundiflorum, were evaluated. The objective was to determine their suitability for construction, especially for structural members. Proximate analyses as well as mineral contents were also determined. The moisture content and density of green samples were 155% (dry basis) and 587 kg/m3, respectively. L. secundiflorum had the highest carbohydrate content while C. deerratus had the least. Radial shrinkage and swelling exceeded longitudinal shrinkage and swelling in all the rattan species, suggesting high anisotropism in movement. Moisture content had significant effect (P < 0.05) on the moduli of elasticity and rupture of all the rattan species. The moduli of elasticity of C. deerratus, E. macrocarpa and L. secundiflorum were 3396, 516 and 11 106 N/mm2 respectively. The strength properties of the rattan canes were found to be lower than those of timber species of comparable densities. The physical and mechanical properties of the rattan canes studied were found to be adequate for use as reinforcement in lowly stressed concrete elements, such as frameworks for ferrocement and complex shaped formworks.
对三种藤本植物——毛竹(Calamus deerratus)、大竹藤(Eremospatha macrocarpa)和二花藤(Laccosperma secundiflorum)的物理力学性能进行了评价。目的是确定它们的施工适用性,特别是结构构件。近似分析和矿物含量也被确定。绿色样品的含水率为155%(干基),密度为587 kg/m3。其中,次花草的碳水化合物含量最高,褐花草的碳水化合物含量最低。所有藤本植物的径向收缩和膨胀均大于纵向收缩和膨胀,表明其运动具有高度的各向异性。水分含量对所有藤条品种的弹性模量和断裂模量均有显著影响(P < 0.05)。松柏、大松柏和次花松柏的弹性模量分别为3396、516和11 106 N/mm2。藤条的强度特性被发现比那些密度相当的木材品种要低。研究发现,藤条的物理和机械性能足以用作低应力混凝土构件的钢筋,如钢筋混凝土框架和复杂形状的模板。

The adhesion and bonding properties of bamboo, Gigantochloa scortechinii, were studied. The variables studied were adhesive types, grain orientation (parallel-ply or cross-ply) and bonding properties of strips taken from different parts of bamboo culm, i.e. strips taken near the periphery or near the inner layer or a combination of both. Commercially available adhesives, phenol formaldehyde (PF), urea formaldehyde (UF) and melamine urea formaldehyde (MUF), were used to bond the bamboo strips. The bonded specimens were subjected to plywood shear test in both dry and wet conditions. The study showed that PF resin formulation suitable for the production of tropical plywood was found to be most compatible for bonding bamboo strips; nevertheless, a slightly longer press time is required to ensure sufficient curing of resin. All shear strengths and wood failure percentage of the PF-bonded laminates met the minimum requirement of British standards. The bonding properties of UF-bonded laminates achieved the standard only when tested in dry conditions. Hot press parameters employed for pressing the MUF-bonded laminates was not sufficed to cure the resin. The grain orientation (parallel or cross-ply) of the strips bonded with either PF or UF had no significant effect on the glue bond quality when tested dry. In extreme wet conditions, the parallel-ply laminates were apparently more stable than the cross-ply laminates. Different parts of the bamboo culm significantly affect the resulting glue bond quality. In all conditions, laminates made from peripheral strips gave more stable products than those made either from inner strips or from the combination of both.
研究了竹的粘接性能。研究的变量是竹材不同部位(靠近周边或靠近内层或两者结合)的粘接类型、晶粒取向(平行或交叉层)和粘接性能。采用市售的酚醛(PF)、脲醛(UF)和三聚氰胺脲醛(MUF)三种胶粘剂对竹条进行粘接。粘结试件在干湿两种条件下进行了胶合板剪切试验。研究表明,适合热带胶合板生产的PF树脂配方最适合竹条粘接;然而,需要稍长的压印时间以确保树脂的充分固化。所有的抗剪强度和木材破坏率均达到英国标准的最低要求。只有在干燥条件下测试时,uv粘合层压板的粘合性能才达到标准。采用热压参数压制muf粘合层压板时,树脂固化效果不理想。干燥试验时,颗粒取向(平行或交叉层)对聚氟乙烯或聚氟乙烯胶条的粘接质量没有显著影响。在极端潮湿条件下,平行层合板的稳定性明显优于交叉层合板。竹竿的不同部位对胶接质量有显著影响。在所有条件下,由外围带制成的层压板比由内部带制成的层压板或由两者结合制成的层压板更稳定。

The function and activity of a root system is closely linked to its normal environment, the soil. The soil volume exploited by the two species was calculated and a comparison showed that Calamus rotang exploited more soil volume than C. thwaitesii. The effective soil volume was also found to show an increase in C. rotang when compared to C. thwaitesii. Knowing the effective soil volume, the size of the polybag to be used in the nursery can be adjusted. The root spread of the two species shows that a 30 × 30 × 30 cm pit size will be sufficient for seedlings up to 2 years old. Rooting density is found to be more in the upper 30 cm layer of soil in both species. Root density, total root intensity and fine root intensity are higher in C. thwaitesii when compared to C. rotang. Root surface area also is more in C. thwaitesii. Hence, this species will be more efficient in water and nutrient uptake in the seedling stage. Both species are good soil binders.
根系的功能和活动与其正常环境——土壤密切相关。计算了两种植物的土壤开采量,结果表明,菖蒲开采量大于菖蒲。有效土壤体积也显示出,相比之下,红毛茛的有效土壤体积增加。了解有效的土壤体积,就可以调整苗圃中使用的塑料袋的大小。两个品种的根展表明,30 × 30 × 30厘米的坑大小对幼苗到2岁就足够了。两种植物的生根密度在土壤上部30cm层均较高。根密度、总根强度和细根强度均高于臭参。根表面积也较大。因此,该物种在苗期将更有效地吸收水分和养分。这两种植物都是良好的土壤粘合剂。

Lin'an County, in the Zhejiang Province of China, began to develop large-scale industrial purpose bamboo shoot plantations in the 1980s. The bamboo shoot plantation area in this county increased from 2180 ha in 1982 to 20 000 ha in 2002; at the same time, the annual fresh shoot production increased from 7280 tons to 135 250 tons, annual fresh shoot production value increased from CNY 2.19 million to CNY 328.05 million (1 CNY = about US$ 0.12). The local industry development started from zero to 47 bamboo shoot processing enterprises, the processed bamboo shoot products amount to 114 000 tons per year. From these products, 32 180 tons are exported to international markets, with an export value of CNY 150 million. The annual per capita income of local farmers increased from less than CNY 800 to CNY 5100. This article introduces how the local farmers in Lin'an County developed the local bamboo shoot production from a natural autarkic economy to an dimensional and market-orientated industry. This progress involves Government supports, training for local farmers, construction of demonstration sites and establishment of technical service network and marketing development. This article provides a successful model for developing bamboo sectors in a community with poor conditions and achieves success in a comparatively short period of time.
中国浙江省临安县在20世纪80年代开始开发大规模的工业用途竹笋种植园。该县竹笋人工林面积由1982年的2180公顷增加到2002年的2万公顷;同时,年鲜笋产量从7280吨增加到135250吨,年鲜笋产值从219万元增加到32805万元(1元人民币=约0.12美元)。当地竹笋产业发展从无到有,目前已有47家竹笋加工企业,年加工竹笋产品达11.4万吨。其中出口国际市场32 180吨,出口额1.5亿元。当地农民年人均收入从不到800元增加到5100元。本文介绍了临安县当地农民如何将当地竹笋生产从自然自给经济发展成为规模化、市场化的产业。这一进展包括政府支助、培训当地农民、建造示范场址、建立技术服务网和发展销售。本文为贫困社区发展竹业提供了一个成功的模式,并在较短的时间内取得了成功。

Bamboo production chain in Ecuador 厄瓜多尔的竹子生产链
Q4 Agricultural and Biological Sciences Pub Date : 2003-12-01 DOI: 10.1163/156915903322700377

A production chain study of Guadua angustifolia was carried out for Ecuador in order to get a better insight in the products and actors involved in the growing, manufacturing, trading and end use of this indigenous bamboo species. The study revealed a whole variety of uses ranging from whole, round bamboo culms to parquet flooring. Most of the Guadua consumption is domestic and for household or construction uses. The export market is limited and mainly concentrated on bamboo poles for the construction sector in Peru. The largest potential markets seem to be national demands for the agricultural and construction sectors. Although there is some experience with the manufacturing and exportation of Guadua products, most actors involved along the chain present serious shortcomings in quality control and sustainability of the production. The growing interest in bamboo as an alternative natural product and the opening up of markets mean new opportunities for Ecuador, although much work has to be done on information gathering and promotion of Guadua as a new high quality product. The recent conformation of the National Consultative Council for Bamboo may lead to an increment of the interest in and competitiveness of the sector.
为了更好地了解这种本地竹子品种的产品和参与其种植、生产、贸易和最终使用的行动者,我们在厄瓜多尔开展了一项瓜瓜生产链研究。该研究揭示了竹子的各种用途,从完整的圆形竹竿到拼花地板。瓜瓜的大部分消费是在国内,用于家庭或建筑用途。出口市场有限,主要集中在秘鲁建筑部门使用的竹竿。最大的潜在市场似乎是国家对农业和建筑部门的需求。虽然在瓜瓜产品的制造和出口方面有一些经验,但在生产的质量控制和可持续性方面,大多数参与者都存在严重缺陷。人们对竹子作为一种天然替代品的兴趣日益浓厚,市场的开放对厄瓜多尔来说意味着新的机遇,尽管在收集信息和推广瓜多作为一种新的高质量产品方面还有很多工作要做。最近成立的全国竹子咨询委员会可能会增加对该部门的兴趣和竞争力。

The world population reached 6 billion in 1999 and at the current growth rate is estimated to reach 7 billion in 2010 with the overwhelming share in developing countries. However, the momentum of poverty alleviation in the developing countries has not kept pace with the population growth. This has serious implications on increased poverty in the regions. One of the visible indicators of the growing poverty is 'lack of shelter'. Reports reveal that millions of people live in hovel 'life- and health-threatening homes', simply due to their inability to afford the houses. This demands seriously to look for an alternative housing materials that are cheap, widely available and require less technical know-how. Bamboo has been found being an excellent building material due to its versatile characterises. It is estimated that more than a billion people live in bamboo houses, mostly in developing worlds. Additionally, its ecological and economical characteristics have made it a sustainable building material. In the past, bamboos were only used to build traditional hovel. However, it has gradually received an increased recognition as a building material. Few development organisations have initiated large-scale bamboo building programme to build houses for low to middle income groups. The projects were highly successful in achieving its main objective i.e. to provide shelter to poor families. This paper mainly deals with the successful stories of three housing projects using comparative assessments of cost and technical aspects. The ultimate objective of the paper is overview the applicability and market potentials of those housing projects for low-income groups in other regions of the world.
世界人口在1999年达到60亿,按照目前的增长速度,估计到2010年将达到70亿,其中绝大部分在发展中国家。然而,发展中国家的减贫势头并没有跟上人口增长的步伐。这对各区域日益严重的贫困产生了严重影响。日益严重的贫困的一个明显指标是“缺乏住房”。报告显示,数百万人住在“威胁生命和健康的房子”里,仅仅是因为他们买不起房子。这就迫切需要寻找一种廉价、广泛可用、对技术知识要求较低的替代住房材料。由于竹子的多用途特性,人们发现它是一种很好的建筑材料。据估计,有超过10亿人居住在竹屋中,其中大部分在发展中国家。此外,它的生态和经济特性使其成为一种可持续的建筑材料。在过去,竹子只被用来建造传统的茅屋。然而,作为一种建筑材料,它逐渐得到了越来越多的认可。很少有发展组织发起大规模的竹建筑项目,为中低收入群体建造房屋。这些项目非常成功地实现了其主要目标,即向贫困家庭提供住房。本文主要从成本和技术两方面比较分析了三个住宅项目的成功案例。本文的最终目的是概述这些住房项目对世界其他地区低收入群体的适用性和市场潜力。
