青海东部农区高产优质燕麦品种筛选 总被引:1,自引:0,他引:1
为筛选出适宜青海东部农区种植的优质燕麦(Avena sativa)品种,以8个当地主栽燕麦品种为供试材料,对其农艺性状、产量和品质进行比较分析,并利用隶属函数法进行综合评价。结果表明,开花期8个燕麦品种的饲草产量及品质从高到低依次为青海444>青海甜燕麦>青燕1号>青引1号>加燕2号>白燕7号>青引2号>林纳,其中青海444饲草产量最高,达39091.29 kg·hm^-2,青海甜燕麦排名第2,且两者纤维含量低,适口性较好;青燕1号饲草产量、粗蛋白含量较高。因此收获饲草建议种植青海444、青海甜燕麦和青燕1号。成熟期8个燕麦品种的种子产量及饲草品质综合评价从高到低依次为白燕7号>青海甜燕麦>青燕1号>林纳>青海444>青引2号>加燕2号>青引1号,白燕7号粗蛋白含量(3.74%)最高,但白燕7号的种子产量(5528.01 kg·hm^-2)低于林纳(5888.69 kg·hm^-2),青燕1号种子产量较低,因此以种子高产为目的建议种植白燕7号、青海甜燕麦和林纳。 相似文献

<正> 许多地区实践证明,种植优质牧草饲养优质牛、羊是农民致富的好路子。波尔山羊是世界上公认的肉用型良种山羊品种,也是我国21世纪发展羊业生产和改良品种的最适合品种之一。该羊以适应性广、生长速度快、肉用性能好、繁殖率高、抗病力强、耐粗饲而著称于世,有“肉羊之父”之称,在我国广大地区均可喂养。其科学饲养方法是:草场放牧与圈养舍饲相结合。养好波尔山羊的关键在于让羊吃饱吃好,饮水充足。草场放牧时间每天在7h以上,种草可充分保证羊的草料供应。 种草养牛养羊还有四大好处:一是有利于提高饲料的营养价值,催生催长。优质牧草蛋白质的含量在20% 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

近几年,世界饲用添加剂市场增长较快,预计今后将进一步增长,据世界粮农组织(FAO)首领会议的倡议,到2015年,将使世界营养不良的人口削减一半,其间,肉制品将会以每年2%的速度增长,特别是加快猪肉和禽肉增长。这将促进世界添加剂,尤其是蛋氨酸和赖氨酸需求量的增加。 相似文献
