چکیده

به منظور ارزیابی عوامل فنی سمپاش توربینی‏زراعی بر میزان بادبردگی، قطرقطرات به هنگام سمپاشی و تحلیل رگرسیونی آن، تحقیقی در مزارع کلزای دانشگاه کشاورزی و منابع طبیعی رامین خوزستان در سال 1394 انجام شد. آزمایش به صورت آزمون فاکتوریل سه عامله در قالب طرح کاملاً تصادفی با سه تکرار انجام شد. تیمارهای آزمایشی شامل فشار سمپاشی با سه سطح 10، 25 و 35 بار، دورپروانه با دو سطح 1998 و 2430 دور در دقیقه و سرعت پیشروی با دو سطح 9 و 5/13 کیلومتر بر ساعت بودند. نتایج حاصله در سطح معنی‏داری 1% نشان داد با افزایش فشار سمپاشی، دور پروانه و سرعت‏پیشروی، میزان بادبردگی افزایش، میزان نشست و قطر قطرات کاهش می‏یابد. نتایج حاصل از تحلیل رگرسیون بادبردگی، نشست و قطر قطرات نشان داد فشار سمپاشی بیشترین تاثیر رابر بادبردگی، میزان نشست و قطر میانه حجمی 50% دارد.

چکیده [English]

To evaluate the technical factors affecting drift and droplet size of turbo liner sprayer and its regression analysis while spraying, a research was conducted in canola fields at the Ramin Agriculture and Natural Resources University of Khuzestan in1394 year. Three-factor factorial experiment with three replications in a completely randomized design was performed. The first factor was the pressure of the sprayer with three levels (10, 25 and 35 bar), the second factor was fan speed with two levels (1998 and 2430 rpm) and the third factor was forward speed at two levels (9 and 13.5 km/ hr). With increasing spraying pressure, fan speed as well as forward speed, the drift was increased and the droplet size and sediment were decreased at the level of significant 1% value. According to the results of linear regression analysis for drift, sediment and droplet size, the pressure has the greatest effect on drift, DV50 and sediment.
