随着蚕业生产的发展和市场需求的变化,全面生产优质蚕茧已成为广大蚕农和缫丝企业的迫切要求。实践证明,使用方格蔟上蔟并加上合理的蔟中管理,是提高蚕茧质量的关键。为此,不少蚕区为提高蚕茧质量,增强市场竞争力和提养蚕效益,要求蚕农应用方格蔟,但由于缺乏相应的上蔟技术和推广方法,致使在方格蔟使用中出现了一些问题,影响了推广进度和使用效果。针对这种情况,笔者通过多年蚕桑基点的实践探索,总结了一套简便易行、效果显著的上蔟技术。现介绍如下:1上蔟前准备1.1备足方格蔟每张蚕种要备足190片方格蔟。新方格蔟要先用蚕沙浸出液或桑叶汁… 相似文献

在蚕桑生产上推广应用纸板方格蔟,改善上蔟条件,可以有效提高上茧率、出丝率和生丝品位,是提高蚕茧质量和蚕业总体效益的重要措施。我们在纸板方格蔟上蔟技术推广中,通过总结群众经验,综合推广应用了蚕匾育、蚕台育、地蚕育等熟蚕自动登蔟,熟蚕高密度自动上蔟,蔟片引蚕清场,喷射火焰省力除浮丝,推广162孔方格蔟和新蔟简易除异味等纸板方格蔟上蔟技术。取得上蔟省时省力,操作简单易行,蔟片寿命延长,效益提高,群众接受快的良好效果。并在一定程度上解决了蚕匾育方格蔟上蔟操作较繁琐问题,有力促进了黄山市纸板方格蔟上蔟技术推广工作的全面展… 相似文献

蚕的上蔟．是养蚕的最后一道工序，上蔟技术是否合理．对提高蚕茧产量和质量十分关键，生产上常被蚕农所忽视。近年来，我市一方面大力推广应用方格蔟．坚决淘汰草笼和塑料折蔟，另一方面不断强化和规范方格蔟使用技术，动员蚕农把好上蔟技术关，蚕茧质量得到了显著提高。现将我市方格蔟使用技术要点介绍如下。 相似文献

上蔟是养蚕最后的重要工作,是保证蚕茧丰产丰收的重要一环,也是决定蚕茧品质好坏的关键环节.同时,上蔟也是养蚕劳动力最集中的时候,工作非常繁忙,在现代规模蚕桑生产中这种现象更为突出.因此选用优良蔟具方格蔟并贯彻合理的蔟中保护,是实现蚕桑生产省工节本、优质高产高收益最行之有效的办法. 相似文献

纸板方格蔟是目前蚕桑生产上最好的蔟具，是提高茧质和效益的最佳途径。在上蔟时需准备比养蚕区大1．5倍的上蔟室，很多蚕农就在室外搭棚上蔟，遇到气温高时蚕儿高温吐丝形成很多双宫茧多层茧影响上茧率，遇到刮风下雨时蚕茧容易被淋湿影响茧质。怎样才能避免这些情况的发生，又不多占上蔟室。下面我就活动蚕台与方格蔟的配套使用同大家探讨一下，供参考： 相似文献

大丰市方强、三龙地区是江苏虹达集团优质蚕茧基地。2002年至2008年，该地区累计发展育71—1新品种桑园2000亩，初具栽桑、养蚕、加工为一体的生产规模。几年来，我们一直把提高蚕茧质量作为稳步发展蚕桑、增加经济效益的关键措施来抓，指导农户坚持科学养蚕，使本地区的纸板方格蔟的使用率达95％以上。开始几年，地蚕农蚕儿上蔟均以手捉或蔟片直接平铺在蚕座上让蚕儿自由上蔟，然后将蔟片移到室外预挂作为省力化上山。这种方法虽比过去省事，由于我地裁桑养蚕大户多，一季饲养10张蚕种以上的户占总养蚕户40％以上，蚕儿上蔟时，平放蔟片、搁挂蚕蔟、蚕蔟翻转等需要调用许多劳力，有时蚕儿上山时遇到不良天气，在室外上山即难以招架。因此，从2007年春蚕期我们又进一步研究改进上蔟方法，先在三龙镇龙东村张汉香、方强镇长坍村刘仲培等蚕桑科技大户示范应用在大棚内安装钢缆，蚕儿成熟后把方格蔟片直接挂在钢丝线上，让蚕儿全自动上山。 相似文献

随着社会经济的高速发展,传统的劳动密集型养蚕模式正在向省力高效的饲养模式转变,为探明小蚕标准化共育、5龄斜面立体条桑育和方格蔟自动上蔟等省力高效养蚕技术的应用效果,2016年分别在云南省普洱市景东彝族自治县、墨江哈尼族自治县选择一定数量的农户开展相关试验。试验结果表明:小蚕标准化共育技术的应用,能够获得稳定的蚕茧产量,比未采用小蚕标准化共育的平均盒种产茧量提高11.23%;5龄期采用斜面立体条桑育比普通片叶育平均盒种产茧量提高27.75%;方格蔟自动上蔟技术的应用,较传统的人工拾取法上蔟盒种用时减少81.35%。若将3种省力高效的养蚕技术结合应用,对减少养蚕用工、降低劳动强度、提高蚕茧产量和质量将会发挥重要作用,有助于实现蚕农增收增效的目的,继续保持养蚕业的持续稳定发展,在蚕桑生产上具有较广阔的推广应用前景。 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
