世界苹果生产现状和发展趋势 总被引:2,自引:0,他引:2
随着世界经济一体化的形成和发展,苹果的生产者、经营者和消费者均将在全球统一的大市场中竞争。了解世界范围内苹果的生产现状和发展趋势,将有助于我国采取适当措施解决目前苹果生产中的主要问题,加快由苹果生产大国向生产强国转变。 1 生产现状 据FAO统计,2002年亚洲苹果产量占世界的54.1%(其中中国占世界的35.8%,其他亚洲国家包括伊朗、土耳其、印度、韩国和日本约占世界的18.3%),欧洲占27.7%,亚欧两洲占世界的81.8%,北美和整个南半球产量相当,均低于世界的10%。从苹果单产可反映生产技术水平和果品质量:亚、欧、非单产较低(约… 相似文献

The crops harvested from maiden plants of Redgauntlet, Cambridge Vigour and Cambridge Favourite, rooted at intervals from April to November, have been examined in detail. Total crop decreased with later rooting dates, but average berry weight increased. This is attributed to the initiation of potentially larger receptacles on the flowers, to a higher proportion of primary flowers and to better berry development on the later-rooted plants. Usually the heavier total yield of early-rooted runners was due to the production of greater numbers of smaller berries, which adversely affected the profitability of the crop.The actual yield of the plants examined was only one half to two-thirds of the possible yield had all the flowers initiated produced full-sized berries. The shortfall has been examined and attributed to a serious failure of some flowers to produce berries of any sort, coupled with poor berry development resulting in the formation of fruits that were only two-thirds to four-fifths of their possible size. Fields for study are indicated that offer the prospect of substantial increases in yields. 相似文献

Abstract This paper focuses on the cropping systems in central European countries such as Belgium, The Netherlands, UK, Ireland, Germany, Switzerland and the northern part of France and Italy. During the last decade there has been a consistent increase in programmed “out-of-season” strawberry production in several central European countries. This is being achieved in part, by using cultivars with different cropping seasons, but mainly by sequential planting of cold-stored plants and by growing strawberries in greenhouses and plastic tunnels. These methods have made it possible to extend the strawberry production for 11 months, from the end of February until mid January in central European countries with moderate climates. 相似文献

世界葡萄发展趋势及产销概况 总被引:4,自引:0,他引:4
葡萄为世界四大水果之一,1985年以前,葡萄产量和面积在水果生产中列世界第一。1985年至今,葡萄产量位居柑桔之后,名列第二(2000年6242.6t,占世界水果总产量的15.89%),但面积仍为水果之首(2000年不足200hm^2,占世界水果总面积的13.7%)。近40年来世界葡萄生产格局虽有所变化,但欧洲作为世界葡萄、葡萄酒的最大生产和消费区的格局并未动摇。近20年,我国葡萄生产迅速,尤其是近3-4年发展更快,可以说进入了我国第三个发展高峰期。为了便于广大葡萄专业户了解世界葡萄生产趋势及动态,做到知已知彼,现把有关资料汇总分析如下,供大家参考。 相似文献
