چکیده

مدل‌های شبیه‌سازی عملکرد گیاه برای مدیریت آب در مزرعه و بهینه‌سازی بهره‌وری آب کاربرد زیادی دارند. مدل آکواکراپ بر اساس پاسخ عملکرد محصول به آب توسط سازمان فائو توسعه‌یافته است. هدف از انجام این پژوهش واسنجی دو پارامتر متغیر درجه روزرشد تا رسیدن محصول و ضریب بهره‌وری نرمال شده برای گیاه جو در منطقه پاکدشت بود. آزمایش‌ها در سال زراعی 94- 1393 در مزرعه پردیس ابوریحان انجام شد و تیمارهای آزمایش شامل سه تقویم زراعی زودهنگام، کاشت به‌موقع و دیرهنگام بودند. مقدار درجه روزرشد از شروع جوانه‌زنی تا رسیدن محصول و ضریب بهره‌وری نرمال شده با استفاده از داده‌های واسنجی و روش سعی و خطا به ترتیب 1260 درجه و 8/14 گرمبر مترمربع برآورد شد. نتایج با استفاده از داده‌های صحت سنجی نشان داد، مدل واسنجی شده با ضریب تعیین 99/0 و جذر میانگین مربعات خطای 59/0 تن در هکتار تطابق خوبی با داده‌های اندازه‌گیری شده دارد.

چکیده [English]

Crop Simulation models are used for water management in farms and are widely used for optimization of water use efficiency. AquaCrop model is based on yield response to water that developed by FAO. The objective of this study was calibration of two parameters, including growing degree days from sowing to maturity (GDD) and water productivity normalized (WP) for barely in Pakdasht region, Iran. The experiments were done in 2014-2015 and the treatments were three crop calendars, including early, normal and late planting. Using calibration data and try and error method, GDD and BWP were calculated 1260 degree and 14.8 gram/m-2, respectively. The results showed that calibrated model provided close agreement with the reference values, with a coefficient determination of 0.99 and root mean square error of 0.59 ton ha-1.
