چکیده

در مناطق جنوبی استان فارس درختی که بیشتر جلب توجه می‌کند کنار (WilldZiziphus spina-christi (L.)) است. به‌دلیل زادآوری محدود این گونه در طبیعت، سالانه تعداد زیادی نهال توسط بخش اجرا برای کاشت توزیع می‌‌شود، اما به‌واسطه خشکی و گرمای شدید مناطق گرمسیری اکثراً استقرار نیافته و خشک می‌شوند. به‌منظور استقرار نهال‌های کنار و یافتن مناسب‌ترین دور آبیاری، در آزمایشی در قالب طرح بلوک کاملاً تصادفی با چهار تیمار و سه تکرار، اثر دور آبیاری در استقرار آنها مورد بررسی قرار گرفت. تیمارها شامل دورهای آبیاری 15، 30 ، 45 روز و بدون آبیاری بود. این تحقیق در شهرستان لار در استان فارس انجام گرفت و آبیاری فقط در سال اول انجام شد و بعد از اتمام آبیاری، درصد زنده‌مانی و ارتفاع نهال‌ها در سال دوم اندازه‌گیری شد. نتایج آزمایش نشان داد که اثر تیمارهای دور آبیاری بر میانگین ارتفاع نهال معنی‌دار بود، لیکن بر درصد زنده‌مانی نهال اثر معنی‌داری نداشت. تیمارهای دور آبیاری 30 و 45 روز اختلاف معنی‌داری نداشتند، اما نهال‌های تیمار آبیاری 30 روزه از وضعیت بهتری برخوردار بودند. با توجه به نتایج این آزمایش، دور آبیاری 30 تا 45 روز با حجم آبیاری 30 لیتر در هر دور آبیاری در سال اول، برای استقرار نهال کنار پیشنهاد می‌شود.

چکیده [English]

In southern parts of Fars province in Iran, Christ's Thorn Jujube (Ziziphus spina-christi) is considered as the dominant species amongst other woody species. However, the lack of its ability for natural regeneration is coupled with high mortality rates of cultivated individuals. Moreover, a common drought within the arid areas of Iran contributes to those limitations. In order to investigate the effect of irrigation intervals on establishment of Z. spina-christi saplings, a complete randomized blocks design with 4 treatments and 3 replications was conducted across a study area near Lar, Fars province. Treatments included irrigation intervals of 0, 15, 30, 45 days, where irrigation was solely done in the first year. Following this, the healthy saplings as well as the heights were inventoried in the second year to determine the sapling establishment as a function of the most appropriate irrigation. The results showed significant effect of treatments on sapling height. However, no significant effect was observed for number of saplings. Therefore, the irrigation intervals 30 and 45 days during the first year, each with 30 litters are suggested for establishment of Z. spina-christi saplings.
