为评估鸣声驱鸟技术在林果生产中的应用效果,于2009年5月在北京市海淀区的樱桃果园,选取苍鹰(Accipiter gentilis)鸣叫、喜鹊(Pica pica)惊叫和灰喜鹊(Cyanopica cy-ana)惊叫,构建3种不同驱鸟情景模式;并于2010年4-5月在室内对果园主要害鸟(喜鹊和灰喜鹊)进行个体适应性测试。配对样本t检验结果显示:播放苍鹰鸣叫显著降低果园内喜鹊的数量(P<0.05),并且对灰喜鹊和麻雀(Passer montanus)数量的降低具有倾向性显著效果;不同驱鸟情景模式下,果园害鸟会选择不同的防御行为。在实际运用过程中,应该采用综合防治方法,权衡经济投入-产出比,并建立驱鸟效果评估机制,最终达到驱赶果园害鸟的目的。
In order to assess the effect of the application of the technique of songbird driving in the fruit production, we selected the Accipiter gentilis, the Pica pica, and the gray magpie in the Cherry Orchard in Haidian District, Beijing in May 2009 (Cyanopica cy-ana) exclaimed and constructed 3 different bird-repellent bird scenarios. In April-May 2010, they conducted individual adaptability tests on the major orniths of the orchard (magpie and gray magpie) indoors. Paired-samples t-test showed that playing the Goshawk Tweet significantly reduced the number of magpie in the orchard (P <0.05), and had a predominant effect on the reduction of the number of Passer montanus and Gray magpie. In different bird repellent scenarios, Orchards bird will choose a different defensive behavior. In practice, we should adopt a comprehensive prevention and control method to weigh the economic input-output ratio and establish a mechanism to evaluate the effect of bird dispersal and finally achieve the goal of expelling pests from orchards.
