چکیده

با توجه به شرایط اقلیمی کشور ایران و مشکل کم­آبی و کمبود سرانۀ فضای سبز، بهره­گیری از شیوه­های مناسب به‌منظور کاهش مصرف آب در بام­های سبز ضرورت دارد. به این منظور آزمایشی به‌صورت فاکتوریل در قالب طرح کامل تصادفی در سه تکرار در سال 1393 بر بام بخش تأسیسات گلخانه­های پژوهشی دانشگاه شهرکرد با استفاده از گیاه گازانیا به اجرا درآمد. عامل اول شامل ورمی­کمپوست (حجم/حجم) در سه سطح 0، 4درصد و 8درصد و عامل دوم در چهار سطح ابرجاذب (هیدروژل) شامل 0، 250، 500 و 1000 گرم بر مترمکعب طراحی شد. آبیاری بر پایۀ نیاز آبی بستر شاهد در نظر گرفته شد. پس از گذشت چهار ماه از کاشت نشاها، اندازه­گیری قطر گل و شمارش شمار گل­ها آغاز شد. شاخص­های دیگری مانند میزان آب مصرفی، وزن تر و خشک اندام‌های هوایی و وزن تر و خشک ریشه اندازه­گیری شدند و نتایج نشان داد، تیمارهای دارای ورمی­کمپوست و هیدروژل افزون بر مصرف کمتر آب، موجب بهبود برخی ویژگی­های رویشی و زایشی گیاه مانند وزن تر اندام‌های هوایی، قطر گل و شمار گل شده است.

چکیده [English]

Regarding to Iran’s climate and water shortage problems and also low green space capitation, it is essential to use different methods to decrease water consumption in green roofs. Therefore, a factorial experiment in a completely randomized design with three replications was conducted in 2013 in research greenhouse complex roof of Shahrekord University using Gazania hybrida. The first factor consisted of vermicompost at three levels (0%, 4%, and 8%) and the second factor was conducted at four levels of superabsorbent (hydrogel) consisted of 0, 250, 500 and 1000 g/m3. Irrigation was considered based on water usage of control substrate. Four months after transplanting, measuring the flower diameter and the number of flowers were initiated. Also, other indices such as water use, dry and fresh weights of shoots and roots were measured and the results showed that vermicompost and hydrogel treatments not only resulted in less water consumption, but also improved plant vegetative and generative traits such as shoot fresh weight, flower number and diameter.
