| چکیده | ||
| ابتداییترین و متداولترین معیار فراهمی آب خاک برای گیاه "آب قابل استفاده گیاه (PAW)" است که دسترسی یکنواخت آب را بین دو حد پتانسیل ماتریک (معادل رطوبت ظرفیت مزرعهای تا پژمردگی دائم) فرض می‌کند و از سایر عوامل محدود کننده فراهمی آب برای گیاه صرف‌نظر مینماید. معیارهای جدیدتر فراهمی آب مانند "ظرفیت آب انتگرالی (IWC)"، محدودیت‌های ناشی از تهویه نامناسب، زهکشی سریع، مقاومت فروروی خاک و شوری را مدنظر قرار میدهد تا میزان آب قابل استفاده در خاک را به درستی برآورد نماید. در این پژوهش به منظور مقایسه کارایی دو معیار PAW و IWC، در یک باغ پسته تحت سامانه آبیاری قطرهای، با اندازهگیری ویژگیهای فیزیکی و هیدرولیکی خاک، مقدار PAW و IWC محاسبه و با استفاده از آنها دو مدیریت آبیاری و تعیین گردید که بهترتیب دور آبیاری 8 و 12 روز و مدت آبیاری 6 و 12 ساعت بهدست آمد. پس از صحت سنجی مدل هایدروس برای شرایط باغ که دقت بالای مدلسازی را نشان داد، توزیع شوری و جذب آب گیاه برای دو مدیریت آبیاری مدلسازی شد. نتایج حاصل از مدلسازی نشان داد که در شوری خاک به مناطق دورتری از ریشه درخت رانده شده و ناحیه با سطوح شوری پایین که نقش موثری در جذب آب دارد گسترش مییابد. از این رو میتوان بیان کرد که در مقایسه با آب بیشتری در دسترس گیاه قرار میدهد. براساس مدلسازی صورت گرفته در و به ترتیب 7/63 و 1/48 درصد از نیاز رطوبتی گیاه تامین شد. بنابراین با استفاده از معیار IWC، مدیریت آبیاری صورت گرفته میتواند تطابق بهتری با شرایط مزرعه داشته و تنشهای کمتری متوجه گیاه شود. | ||

| چکیده [English] | ||
| Plant Available Water (PAW) is the most common criteria for Soil Available Water (SAW) to plants which assumes uniform water availability between two matric potential limits (field capacity to permanent wilting point) and ignore other limiting factors for plants. Integral Water Capacity (IWC) is one of the most recently developed criteria for SAW that consider all soil restrictions including unsufficient aeration, rapid drainage, resistance of root penetrability and salinity, in order to estimate the SAW properly. In this study, in order to compare the applicability of PAW and IWC criteria in irrigation management, soil physical and hydraulical properties of a pistachio garden, with drip irrigation system, were measured and PAW and IWC were calculated. Based on these criteria, two irrigation regimes ( and) were determined. According to the results, the irrigation periods for and were 8 and 12 days and irrigation duration were obtained 6 and 12 hours, respectively. Soil salinity distribution and root water uptake in two irrigation regimes were simulated using HYDRUS-2D model after validation for garden condition which showed a high accuracy for modeling. The results showed that in , soil salinity is driven to areas farther from the root of the tree and the area with low salinity levels, which plays an effective role in water absorption, are expanded. Based on the simulation, 63.7% and 48.1% of crop water requirement were provided through and managements, respectively. Therefore, by using IWC index, irrigation management could have a better accommodation to field conditions and leads to less water and salinity stress. | ||
