چکیده

در این پژوهش تاثیر سوپرجاذب نانوکامپوزیت و تنش خشکی بر خصوصیات رشدی چمن اسپورت بررسی گردید. این آزمایش به­صورت فاکتوریل در قالب طرح کاملا تصادفی با سه تکرار و با اعمال دو فاکتور نوع بستر (کود دامی، سوپرجاذب نانوکامپوزیت به­همراه کود دامی و ورمی­کمپوست به­علاوه سوپرجاذب نانوکامپوزیت) و دوره آبیاری (بدون تنش، آبیاری پنج روزه و 10 روزه) در فضای باز اجرا گردید. نتایج نشان داد که تاثیر بستر حاوی نانوکامپوزیت سوپرجاذب بر صفات وزن تر و خشک و ‌عمق نفوذ ریشه معنی­دار گردید. تاثیر دوره آبیاری بر صفات وزن تر، وزن خشک، عمق نفوذ ریشه، میزان کلروفیل b، کلروفیل کل، هیدرات کربن، نشت یونی معنی­دار بود و در دوره آبیاری پنج روزه کیفیت ظاهری چمن حفظ گردید. معنی­دار بودن اثر متقابل نوع بستر و فاصله آبیاری در میزان پرولین و کلروفیل a نشانگر افزایش توان عبور چمن از تنش در بستر حاوی نانوکامپوزیت با دوره آبیاری پنج روزه بود.

چکیده [English]

This experiment was carried out based on a completely randomized design with three replications and two factors by applying a type of bed (manure, manure plus superabsorbents nanocamposite and vermicompost plus superabsorbents nanocamposite) and irrigation period (no stress, 5-day and 10-day) in the farm. Shoot and root height, fresh and dry weight, chlorophyll content, root penetration depth, carbohydrate, chlorophyll, prolin, carotenoid and ion leakage cnotents were measured in this experiment. The results showed that the bed containing nanocomposite superabsorbent was significant on fresh weight, dry weight and root penetration depth. The effects of irrigation period were significant on fresh weight, dry weight, root penetration depth, chlorophyll b, chlorophyll, carbohydrate, electrolyte leakage and quality (NTEP). The quality was maintained in five-day irrigation period. The interaction between bed and the irrigation period was significant for proline and Chlorophyll which indicating the tolerance of five-day irrigation period in the bed containing superabsorbents nanocomposites.
