چکیده مقاله :

به منظور مطالعه اثر پیش تیمار امواج مغناطیسی و امواج فرا صوت برعملکرد ذرت علوفه ای 704 آزمایشی در سال زراعی 1392 در مزرعه ای واقع در روستای بدلبو در 15 کیلومتری شمال ارومیه به صورت فاکتوریل در قالب طرح بلوک های کامل تصادفی با 3 تکرار و 2 فاکتور انجام شد. عامل اول میدان مغناطیسی شامل تیمارهای 40، 80 میلی تسلا در زمان 20 دقیقه و شاهد بود، عامل دوم امواج صوتی شامل دو سطح با فرکانس های 40 و 80 کیلو هرتز در زمان دو دقیقه به همراه شاهد بود. نتایج نشان داد که صفات ارتفاع بوته، تعداد گره، مساحت برگ، نسبت وزن بلال، در صد پروتیئن و وزن علوفه تحت تاثیر امواج صوتی قرار گرفتند. صفت تعداد گره نیز تحت تاثیر میدان مغناطیسی قرار گرفت و اثر متقابل تاثیر میدان مغناطیسی در امواج صوتی بر صفات ارتفاع بوته، تعداد برگ، وزن تر ساقه و درصد پروتیئن معنی دار شدند. تلفیق دو پیش تیمار امواج فراصوتی و مغناطیسی در سطح امواج متوسط باعث افزایش 20 در صدی علوفه گردید.

چکیده انگلیسی:

To study the impact of pre-treatment of magnetic and ultra sound waves of the yield of forage corn of 704, an experiment was carried out in factorial complete random blocks with three replications and two factors on a field in Badalboo village, 15 km north of Urmia in 1392. The first factor was the magnetic field including 40, 80 milli-tesla in 20 minutes and the control ; the second factor was the sound waves including two levels with 40, 80 k. h. in two minutes with control. The results showed that the traits of the stalk height, the number of nodes, leaf area, the corn weight ratio, percentage of the protein, and the weight of forage were under the impact of sound waves. The trait of the number of nodes was also under magnetic field. The interactive impact of magnetic field in second waves was significant on the stalk height, number of leaves, wet weight of the stalk, and percentage of protein. The combination of two pre-treatment of ultra-sound and magnetic wave in average wave level caused %20 increase in the forage.
