马来西亚:马来西亚木材出口协会称,高昂而且变化无常的欧洲和中东的运费使行业一直受到困扰。2008年平均运费大约是每个40ft集装箱1800美元,2009年6月跌到600美元,2010年3月则涨到了3200美元,以后在2800美元徘徊。 相似文献

森林与木材工业是马来西亚经济命脉的主要组成部分。在亚洲地区于1997年年中陷入金融危机之后,木材工业在马来西亚的经济复苏之中扮演着举足轻重的角色。这得益于过去三年来木材与木材产品强劲的出口。在2002年,马来西亚木材与木材产品的出口与2001年相比增长6.5%达到153亿元马币或40亿美元。木材业出口占马来西亚3,545亿元马币出口总收入的4.3%,其重要性可见一斑。此工业于2001年为226000人提供了就业机会,占当年就业人口的2.4%。以出口而言,传统的初级加工产品如锯材、单板和胶合板的制造依然占了木材工业总出口量的大部分。然而,由于马来西亚国内实施了工业化计划,包括木线(mouldinggs),细木工产品(joinery)与家具在内的深加工业已在过去10年内取得持续稳定地增长。 相似文献

At Ibadan, southwestern Nigeria, papaya trees were intercropped with okra, watermelon, sweet potato, bush greens, jews' mallow and Solanum gilo Raddi. The aim of the experiment was to select crops suitable for intercropping in the alleys of papaya plants in orchards. Sweet potato and Solanum gilo Raddi caused marked reduction in the yield of papaya. Land Equivalent Ration (LER) for papaya intercopped with okra, water-melon, sweet potato, bush greens, jews' mallow and Solanum gilo Raddi were 3.86, 3.13, 2.06, 1.86, 1.60 and 1.54, respectively; indicating that all the combinations were more advantageous than the monocrop of papaya. Monetary value of the mixtures, however, indicated that the inclusion of intercrops of sweet potato or Solanum gilo Raddi, is disadvantageous.Although intercropping in papaya orchards is beneficial, it should be limited to the early vegetative and late fruiting phases of papaya when the Leaf Area Index (LAI) of papaya is low. A relay of okra followed by watermelon or bush greens followed by jews' mallow (or sweet potato grown for fodder) is considered suitable for intercropping the alleys of papaya. 相似文献

间种对油茶幼林生长的影响及效益分析 总被引:1,自引:0,他引:1
选用黄豆、花生、红薯和烟叶4种农作物于油茶幼林内进行间作,研究不同间种模式对油茶幼树树体生长的影响,并对间种不同经济作物的油茶幼林林地经济效益进行分析。结果表明:间种可促进油茶幼林的生长,其中间种黄豆效果最好,树高增加了0.11 m,地径增加了0.04 cm,冠幅增加了0.21 m~2,花芽数增加了20个/枝。间种可增加油茶幼林的经济效益,其中间种烟叶效益最高,经济产出为48 960元/hm~2。综合来看,油茶幼林间种的经济作物宜选择较矮小、具根瘤固氮菌的花生、黄豆。 相似文献

2005.2006年间,在印度喀什米尔地区的克什米尔农业科学大学的试验地对农林兼作体系进行研究,柳树与农作物的间混种植包括柳树,羽衣甘蓝(Brassica oleracea Var.acephala)和球茎甘蓝(Brassica oleracea var.caularapa)。试验地分成几个小区,每个小区(8m×2m)种植4棵两年生的柳树,间距为2m×2m。采用被推荐的间混种植的植株间距和施用的肥料浓度。结果表明:羽衣甘蓝和球茎甘蓝与柳树间混种植得出这种的种植模式的预计效益成本率分别为2.78和2.79,单独的柳树种植效益率为2.66。本研究表明,可以促进蔬菜作物与柳树间混种植模式从而代替单独的柳树种植模式。图1表7参27。 相似文献

Brazil accounts for about 20% of the world production of cocoa, and about 95% of cocoa produced in Brazil is from the southeastern part of Bahia State. Traditionally, cacao is grown in monoculture (though under the shade of various other species). But various crop combinations involving cacao have recently been undertaken by the farmers with encouragement from Brazilian government.As a part of the crop diversification programme in the traditional cacao growing areas and their surroundings, extensive areas are being planted to other plantation crops, mainly clove and rubber and, to some extent, coconut too. Crop combinations have been adopted in some of these new plantings and cacao is an important component of most of such combinations. Whereas several other crops are combined with clove trees, cacao is usually the only species grown with mature rubber trees. Young rubber trees are, however, interplanted with a number of other species. Productive coconut areas are found mostly in sandy soils along the coast so that there is little intercropping. However, scattered farms are found where coconuts are underplanted with guarana, black pepper, cacao, cashew, etc. as done commonly in other parts of Northeast Brazil. 相似文献

Cross‐infectivity of oil palm by Phytophthora spp. isolated from perennial crops in Malaysia 下载免费PDF全文
Bud rot disease or “Pudricion del cogollo” (PC) of oil palm is a major constraint on production in Colombia and neighbouring countries such as Brazil, Costa Rica, Ecuador, Nicaragua, Panama, Peru and Surinam. To date, there are no documented reports of Phytophthora disease of oil palm in South‐East Asia. This research, therefore, was conducted to determine the pathogenic potential of Phytophthora palmivora and Phytophthora nicotianae on oil palm using both in vitro and nursery inoculation experiments. In vitro inoculation of both P. palmivora and P. nicotianae on immature oil palm leaflets caused discoloration within 2 days of inoculation and incubation at 25 ± 1.5°C, 100% RH. Similarly, in nursery trials, lesions formed on the buds (unopened leaflets) 3 days after inoculation with P. palmivora or P. nicotianae zoospore suspensions. No lesions developed on untreated leaflets in either in vitro or nursery inoculation experiments. Phytophthora spp. were re‐isolated from leaflet lesions and confirmed as the inoculated pathogens. 相似文献
