چکیده

در شرایط کمبود آب و خشکسالی روش­های صحیح آبیاری و الگوی کشت مناسب جزء اولویت‌های مطالعات کشاورزی است. در این مقاله به بررسی اصلاح الگوی کشت باغ‌های منطقه­ی خشک و نیمه خشک قیر­و­کارزین استان فارس از درختان مرکبات به خرمای رقم پیارم از دیدگاه منافع اقتصادی و بهره­وری آب در دو شرایط کمبود آب و آب کافی پرداخته شده است. بهره­وری آب در شرایط کمبود آب برای نخل خرما و درخت مرکبات، به ترتیب 22 درصد بیشتر و 16 درصد کمتر نسبت به شرایط آب کافی تعیین شد. طبق نتایج این پژوهش جایگزینی بخشی یا تمام باغ‌های درختان مرکبات منطقه­ی قیروکارزین با نخل خرمای رقم پیارم هم از لحاظ اقتصادی بر اساس نسبت منفعت به هزینه و سود خالص به ازاء حجم آب مصرفی و هم از لحاظ مقدار آب مصرفی در هر دو شرایط کمبود آب و آب کافی در باغ‌های وسیع به صرفه خواهد بود. ولی در باغ‌های کوچک در شرایط کمبود آب کشت نخل خرما و در شرایط وجود آب کافی کشت درختان مرکبات به عنوان انتخاب برتر هستند.

چکیده [English]

Under water scarcity and drought conditions, proper irrigation methods and suitable cropping pattern are among the priorities of agricultural studies. In this research cropping pattern modification of Citrus gardens to Piyarom dates are investigated by evaluating economic benefits and water productivity, considering cases of water scarcity and sufficient water in QiroKarzin region of Fars province. Water productivity of Piyarom dates and citrus under water scarcity condition were respectively 22% higher and 16% lower than those obtained in sufficient water condition. Results also indicated that in large gardens of the study area for both water scarcity and sufficient water conditions, replacement of part or all of citrus orchards with Piyarom dates would be beneficial, based on the ratio of profit to cost and net profit per volume of water consumed and also the amount of water consumption. However, in small gardens under water scarcity condition, Piyarom dates cultivation and under sufficient water condition, citrus cultivation would be the appropriate alternatives.
