林果苗木育苗、种植基地兔害物理防治技术 总被引：1，自引：0，他引：1
随着新疆林果育苗基地、林果业基地建设和大面积推广,野兔啃食林果苗木(树皮)而引起的灾害也时有发生,致使育苗企业和果农蒙受损失。野兔种群中可分为国家重点保护和非重点保护两类,在实际使用生物、化学、物理等灭杀性防治方法的过程中,不易控制和把握,往往会误杀国家重点保护类野兔种群。我们通过多年来的观察和实践,探索出一套既符合环保要求,又不影响生态平衡的物理防治方法。 相似文献

野兔,正在我国西北、华北、东北等地肆无忌惮地蚕食来之不易的生态建设成果。受保护而又带来麻烦的野兔,防,如何防?治,又如何治?陕甘宁———野兔如此猖獗据新华社2月16日报道:“陕西省野兔危害新造林面积达227.4万亩,幼树被害株率最高达60%,兔害已经成为该省生态建设的一大难题。延安、榆林部分地区每平方公里的野兔已高达58只至120只,远远高出每平方公里26只的可容许水平。陕西省林业厅野生动植物保护处处长王万云认为,该省现有野兔约880万只。如不采取有效措施加以控制,野兔每年将以5倍至8倍的速度增长,其危害只会越来越严重。截至2004年… 相似文献

To assess the effects of clearcutting on snowshoe hare (Lepus americanus) relative abundance, we surveyed pellets in 1 m2 circular plots and, vegetation and browse surveys in 4.5 m2 circular plots among four different aged clearcut (30, 20, 10, 5 years post-harvest) and mature forests (>150 years old) in central Labrador, Canada. Data were modelled at three grain sizes: transect (4400 m2), plot (314 m2) and subplot scales (4.5 m2). Betula papyrifera, distance from mature forest edge, tree and herb cover as well as remotely sensed forest inventory data were used as predictors for hare pellets. We found pellet abundance was 5 and 37 times greater (new and old pellets, respectively) in clearcut stands 30 years old than the next highest in 20 year old cuts. There were few hare pellets in the remaining stand ages. B. papyrifera was the most proportionately used browse species and most important of our fine-detailed vegetation in predicting hare pellets. The coarse-detailed, forest inventory and topographic data better predicted hare pellets than the fine-detailed vegetation data. 相似文献

Natural forest recovery on abandoned farmland is hindered by a variety of factors and active restoration plays an important role when quick afforestation is desired.We investigated seedling survival of four transplanted native tree species(Quercus myrsinifolia, Quercus serrata,Aphananthe aspera, and Rhus sylvestris) by experimentally manipulating the vegetation cover, which was mainly dominated by dwarf bamboo(Pleioblastus chino), and herbivore access to the planting sites on farmland that had been abandoned for 15 years at the start of the study. Few transplanted seedlings of any species survived under intact vegetation cover, irrespective of herbivore presence. In gaps in the vegetation cover, winter browsing by Japanese hare(Lepus brachyurus) damaged all species. However,lower browsing frequency and higher resprouting ability after grazing of the seedlings enabled both Quercus species to survive better than the other species. These results indicate that dwarf bamboo and the hare jointly limit the establishment of native trees in old fields. If active afforestation by transplanting seedlings at sites dominated by dwarf bamboo is planned, a combination of vegetation removal, selection of suitable species, and temporary seedling protection will be most effective. 相似文献
