چکیده

امروزه مدیریت بهینه آب آبیاری بسیار ضروری می­باشد و ابزارهای ارزشمندی به نام مدل‌های مدیریتی آبیاری این بهینه‌سازی را تسهیل کرده و بهبود بخشیدند. بدین‌منظور، در آزمایشی دو ساله 84-1383 و 85-1384به واسنجی مدل  AquaCropو بررسی دقت آن در شبیه­سازی شاخص‌های محصول جو در منطقه داراب پرداخته شد. واسنجی مدل از طریق مقایسه­ی نتایج حاصل از مطالعات صحرایی و شبیه‌سازی انجام شد. داده­های اندازه­گیری شده در سال اول برای واسنجی مدل و در سال دوم برای اعتبارسنجی مورد استفاده قرار گرفتند. مقادیر ماده خشک قسمت هوایی گیاه شبیه‌سازی شده توسط مدل با شاخص­های آماریd و NRMSEدر سال اول کشت به‌ترتیب برابر 982/0 و 094/0 و در سال دوم 935/0 و 198/0 و مقدار عملکرد دانه برآورد شده توسط مدل در سال اول کشت به‌ترتیب برابر 981/0 و 172/0 و در سال دوم برابر 992/0 و 103/0 بود. نتایج آزمون‌های آماری نشان دادند که مدل AquaCropاز دقت بالایی برخوردار بوده است.

چکیده [English]

As the population grows and people's living standards rise, the global demand for freshwater is constantly increasing. Agriculture is not only the largest consumer of water in the world, but also one of the cheapest and least efficient consumers with the highest subsidy rates. Nowadays, optimal management of irrigation water is very essential issue and valuable tools calls irrigation management models to improve for this optimizing and Facilitating. For this purpose, the two-year 2004-2005 & 2005-2006 experiment to determine the accuracy of the simulation AquaCrop model calibration and AquaCrop indices barley crop was in Darab-IRAN. Many countries, especially those located in arid and semi-arid areas, need water to produce agricultural products, and many of our country's crops and gardens are also cultivated in the water.
