蚕桑是淳安县的高效生态农业之一,也是该县四大农业支柱产业之一.两年来,在完善茧丝绸行业贸工农一体化管理体制,推进以"公司 农户"为基本模式的蚕桑产业化建设同时,依托桑品种进步,大力发展大田连片种桑;大力推广方格蔟,提高茧丝品质;依托浙江省蚕桑西进,推动现代蚕业示范园区建设,打响了"千岛湖"品牌茧丝,拉长了蚕桑产业链,茧丝绸加工业得到发展.2004年该县蚕茧产量首次突破5000t,在全省排名跃居第4位,蚕茧产值首次超亿元,全县茧丝绸行业首只终端产品--蚕丝被面市,全省唯一的蚕桑科技创新中心落户淳安实施.千岛湖牌茧丝参展省农博会获金奖,千岛湖牌蚕茧为中国著名畅销品牌、省名牌产品,千岛湖牌白厂丝为名牌产品.淳安县将在2007年达到桑园6780hm2、产茧1万t、蚕桑产值2.5亿元、缫丝业实现产值3亿元、茧丝绸行业实现产值超10亿元的目标,实现蚕桑产业更大、更广、更强、更优. 相似文献

蚕桑是淳安县四大农业支柱产业之一,近年来发展迅速,而且茧质综合指标一直名列全省前茅,"千岛湖"牌茧丝在省内外市场有良好声誉.为进一步提高千岛湖牌茧丝质量效益,笔者经分析研究,认为该县蚕茧的一茧丝长指标还有很大潜力.以春茧为例,该县1993~2003年的11年中,平均一茧丝长为1 098.59m,而在生产实践中养蚕比较好的一茧丝长都在1 200m以上,说明广大蚕农在科学养蚕上还存在较大差距,如小蚕饲养加温、5龄盛食期给叶、上蔟适时的选择、养蚕场地、养蚕劳动力素质等差异,影响了蚕儿桑叶食下量,导致蚕茧干壳量高低不一,反映到一茧丝长指标上不够理想.为使该县蚕茧一茧丝长有较大提高,促进茧质更上一层楼,现提出以下技术改进措施. 相似文献

近年来,地处浙西山区的淳安县依托优良的生态环境、健全的产业服务网络以及完善的“公司 农户”、“合同蚕业”产业化机制优势,在加大蚕桑产业结构调整力度、大力建设连片优质新品种桑基地,致力打造千岛湖牌茧丝品牌的同时,十分重视产业的标准化生产。早在2002年5月获得国家工商管理总局“千岛湖”牌桑蚕茧商标注册的同时,本县就成立了《千岛湖牌桑蚕茧》生产地方标准编制小组,开始了标准的拟订,并于2003年4月通过了省级专家的评审且由淳安县质量技术监督局批准发布实施,由此淳安成为了浙江省第一个制定发布品牌蚕茧生产地方技术标准的县(市… 相似文献

淳安县地处浙西山区,气候宜人,环境污染少,发展蚕桑生产具有得天独厚的自然环境优势,是浙江省"蚕桑西进"的重点县之一.自1996年在全省率先进行茧丝绸贸工农一体化改革以来,作为省级骨干农业龙头企业的县茧丝绸总公司充分发挥生产、收烘、经营、行业管理职能等优势,大力实施"千岛湖"品牌茧建设,积极探索"公司 农户"为模式的蚕桑产业化建设新路子,全面推行"合同蚕业",使蚕茧综合质量在浙江省具有明显的优势,"千岛湖"蚕茧于2003年获得浙江省名牌产品,但在净度、茧丝长、茧层率指标上低于全省主产区平均水平,这是制约本县蚕茧质量进一步提高、向国家级名牌产品迈进的瓶颈因素. 相似文献

淳安县是一个经济欠发达的山区县,蚕桑生产是农村经济的支柱产业.自1996年成立贸工农一体化的茧丝绸总公司以来,淳安县蚕桑生产紧紧围绕"调整结构、扩大规模、增加总量、提高质量"这一主题,强化技术服务,推行标准化生产,实施蚕茧品牌战略,着力建设现代蚕业示范园区,不断探索栽桑养蚕新技术、新设施,不断引进推广优良桑、蚕品种,大力推广蚕桑生产实用技术.实现了我县蚕桑产业持续快速稳定发展,品牌建设成效显著."千岛湖"牌蚕茧质量综合指标连续7年名列浙江省前茅,2000年在杭州市农产品博览会上荣获金奖,2003年被认定为省名牌产品.抓住省"蚕桑西进"这一机遇,2004年又取得了历史性突破,蚕桑产值达1.35个亿,蚕茧产量跃居浙江省第四位. 相似文献

When early people made their appearance, zoonotic infectious diseases were already waiting, but epidemic diseases did not appear in human history until people began to live in large numbers under conditions of close contact, mainly during the last 10,000 years. Disease has decimated urban populations, conquered armies, and disrupted society. The focus here is on (1) the plague of Athens and the Black Death; (2) smallpox, influenza, and rabies; (3) avian influenza prion diseases, and foot & mouth disease; and (4) emerging and re-emerging diseases. All have veterinary public health associations. In Athens, Greece, in 430 BC, when the Spartans ravaged the countryside, hordes crowded into Athens so that orderly movements, space in which to live, and adequate supplies of food became impossible. Crowding of any population fosters disease transmission; chaos and disorder enhance it all the more. Out of northern Egypt came a terrible plague from across the Mediterranean Sea. The identity of the plague of Athens remains unsure, but the well-considered conclusion is Rift Valley Fever, a mosquito borne, viral zoonosis. The Black Death, also called the Plague, raged in Asia for centuries. In 1347, the Black Death was brought by a ship out of Asia to Sicily. The scenes of devastation were repeated throughout Europe, with 90% or more of the people dying in city after city. Influenza, too, has been a cause of periodic human epidemics, but the great pandemic of influenza occurred in the last months of World War I. In the years of highest occurrence, more than half the world's population became clinically infected. If veterinary public health had been born earlier, it could have led to elucidating the epidemiology of influenza and the plagues of Athens, Europe, and Asia. In turn, smallpox had also caused continual tragedy. In 1796, Edward Jenner began to harvest pustules of cowpox from children or infected cows and inject them into susceptible children. In 1980, the World Health Organization declared that smallpox had been eliminated from the world. Rabies, though, still strikes terror. A number of animal diseases, broadly termed emerging and re-emerging diseases, need surveillance because they have the potential to impact human health. From late in 2003 to 2007, the highly pathogenic H5N1 influenza virus in poultry infected at least 121 people and caused 62 deaths in four countries. The prion diseases, too, all have very high numbers in concentrated contacts. To control these diseases, veterinary public health is essential, with diagnosis, epidemiological surveillance, clinical manifestations, and prevention as primary measures. 相似文献

On 26th of july 2007 a new case of bluetongue was notified in the Netherlands and on 2nd of august 2007 foot-and-mouth disease was diagnosed in Surrey, England, which raised the threat of having both infections simultaniously in one area. Bluetongue and foot-and-mouth disease have a different pathogenesis, but symptoms may resemble each other at a later stage of infection. The pathogenesis and possible clinical symptoms of both infections are discussed and illustrated with pictures. 相似文献
