چکیده

دقت در طراحی و مدیریت صحیح سیستم­های آبیاری بارانی از عوامل مهم در توسعه و بهبود آن­هاست. بنابراین در این پژوهش، به بررسی نحوه­ی طراحی، اجرا و بهره­برداری از سیستم­های آبیاری بارانی کلاسیک ثابت با آب­پاش متحرک در شهرستان اقلید در فارس پرداخته شد. برای این منظور، هشت سیستم به­عنوان نمونه انتخاب شد. برای ارزیابی این سیستم­ها از معیار­های ضریب یکنواختی کریستیانسن(CU)، یکنواختی توزیع(DU)،بازده پتانسیلکاربرد در ربع پایین (PELQ)، بازده واقعی کاربرد در ربع پایین (AELQ)،بازده کاربرد (Ea)، بازده ترکیبی (Ec)، تلفات تبخیر و بادبردگی (WDEL) و تلفات نفوذ عمقی (DP) استفاده شد. مقادیر متوسط شاخص­های CU، DU، PELQ، AELQ، Ea، Ec،WDEL و DP به­ترتیب برابر 37/73، 82/61، 51/54، 31/52، 50، 1/82، 84/12 و 32/5  درصد به­دست آمد. نتایج این تحقیق بیانگر این بود که دلیل پایین بودن PELQ وAELQ مشکلات مربوط به طراحی و بهره­برداری است. بر­اساس نتایج، می­توان با کاهش فواصل آب­پاش­ها، تنظیم فشار و عدم استفاده از تعداد زیاد آب­پاش به­طور هم­زمان، یکنواختی توزیع را افزایش داد. هم­چنین با کاهش مدت زمان آبیاری، تلفات آبیاری کاهش و بازده ترکیبی و بازده کاربرد آب در سیستم افزایش می­­یابد.

چکیده [English]

Due to the climatic conditions of Iran, the limitations of irrigation resources, and low irrigation efficiency in traditional methods, on the one hand, and the existence of arenas for the development of blue land and the increasing need for food, on the other, application of pressurized irrigation methods as one of the most effective ways to optimally use existing water resources is inevitable (Baradaranhazave et al., 2006). In recent years, the methods of irrigation under pressure, especially the classic sprinkler irrigation with travelling sprinklers have, in general, been used in Fars province, and in the city of Eghlid, in particular. The purpose of the present study was to determine the efficiency of the system after the implementation of the system, the maximum irrigation efficiency of the system, and its difference with the amount available in field conditions.
