چکیده

پرندگان، گاهی اوقات که تعدادشان زیاد است، می­توانند خسارت­های جدی به مزارع غلات وارد سازند. به منظور یافتن راه­کاری مطابق با مسایل زیست­محیطی و مؤثر در کنترل این پرندگان، در این تحقیق، اثر صوت برای دفع آن­ها مورد بررسی قرار گرفت. واحد پخش با معیارهای طراحی زیر توسعه داده شد:1) سه سطح صدای شاهین، توپ گازی و رنجش گنجشک با بسامدهای 1، 5 و 10 کیلو هرتز، 2) صدای ترکیبی توپ گازی و رنجش گنجشک با بسامد 5 کیلو هرتز و 3) در صبح و عصر. نتایج نشان داد درصد پرندگان پرواز کرده نسبت به تعداد پرندگان قبل از ایجاد صدا برای صدای ترکیبی 46/92، توپ گازی 90/82، رنجش گنجشک 58/74 و شاهین 22/48 می­باشد. بین میزان پرندگان پرواز کرده بعد از تولید صدا در بسامد­های مختلف اختلاف معنی­داری وجود نداشت. همچنین مشخص گردید درصد پرندگان پرواز کرده در زمان صبح به میزان 06/8 بیشتر از زمان عصر بوده است.

چکیده [English]

Birds, sometimes numbering in millions, can cause serious damage to grain fields. In order to find a method to accordance with environmental issues and effective in controlling these birds, in this research, the effect of sound was studied for keep birds away. The broadcast unit was developed with the following design criteria: 1) Three sound levels of hawk, gas gun and sparrow distress, with frequencies of 1, 5 and 10 kHz. 2) The combination of the sounds of cannon gas and sparrow distress with a frequency of 5 kHz and 3) In the morning and evening. The result showed percent flight birds was by mixture sound 92.46, gas gun 82.90, sparrow distress 74.58 and hawk 48.22. There was no significant difference between numbers of bird’s flight after sound producing in the different frequencies. Also, it was recognized that percent of flight birds in the morning was 8.06 more than in the afternoon.
