深圳市台湾草,马尼拉草草坪冬季质量及管理状况研究 总被引：7，自引：2，他引：5
对深圳市台湾草、马尼拉草景观草坪进行的研究表明,建植时施用有机肥可以简化管理并提高草坪质量;两种草的高度、密度均较适宜;马尼拉草的色泽、均匀度均优于台湾草;两种划的冬季色泽可以通过灌水施肥达到理想水平;适当地适用有利于控制两种草的高度和维持平整度。 相似文献

遮荫对几种暖地型草坪草成坪速度及其景观效果的影响 总被引：19，自引：4，他引：15
对5种常见暖地型草坪草在不同遮荫条件的成坪速度及其景观效果进行研究观察,结果表明:天堂328、狗牙根、结缕草均随遮荫程度的加大,成坪速度显著减慢或不能成坪,假俭草、马尼拉在遮荫度37%、58%条件下,成坪速度超过对照水平或相当,因此认为,在遮荫地或林下种植草坪时,供试草种中应首选假俭草,其次为马尼拉,另外3个草种不宜作为耐荫草种利用;遮荫提高了各草坪草叶片的叶绿素含量,一定程度上增加了绿色景观效果;遮荫处理不同程度增加了草坪植株的高度、叶片长度、宽度、面积,但降低了叶片的厚度。 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
