چکیده

پژوهش حاضر با هدف ارزیابی و مقایسه جریان انرژی در مزارع گندم شهرستان‌های استان البرز صورت گرفت. شاخص‌های بازده انرژی، افزوده خالص انرژی، انرژی ویژه، بهره‌وری انرژی، شدت انرژی و انرژی ورودی کل و خروجی محاسبه شدند. جامعه آماری تحقیق شامل کشاورزان شهرستان‌های استان البرز در سال زراعی 92-1391 می‌باشد. تعداد نمونه‌ها با توجه به تعداد جامعه آماری استخراج‌شده از جدول مورگان، 273 کشاورز بخش زراعت استان البرز انتخاب گردید.  برای جمع‌آوری داده‌ها از پرسش‌نامه محقق ساخته با ضریب پایایی 91/0 و داده‌های سازمان جهاد کشاورزی استفاده گردید. نتایج نشان داد در بین انرژی ورودی کشت گندم در چهار منطقه، کودهای شیمیایی (MJ/ha28176) و سوخت (MJ/ha22154) بالاترین و نیروی انسانی (MJ/ha85) پایین‌ترین مصرف انرژی را داشتند. در این تحقیق بازده انرژی در مزارع نظرآباد (74/2)، کرج (57/2)، اشتهارد (23/2) و ساوجبلاغ (5/2) به دست آمد. شهرستان نظرآباد با kg/MJ 086/0 و شهرستان اشتهارد با kg/MJ 070/0 بیشترین و کمترین بهره‌وری انرژی را در تولید گندم داشتند در بین چهار منطقه موردمطالعه شهرستان نظرآباد با افزوده خالص انرژی MJ/ha42/90802، شدت انرژی MJ/m221/5 و انرژی ویژه MJ/kg 57/11 از شرایط بهتری نسبت به سه منطقه دیگر برخوردار بود. در مجموع نتایج تحقیق نشان داد که مزارع گندم شهرستان نظرآباد در مصرف انرژی کارآمدتر و مدیریت بهتری نسبت به سه شهرستان دیگر داشتند.

Evaluation and Comparison of Energy Indices in Wheat Farms in Townships of Alborz Province

چکیده [English]

The our purpose of objective is evaluation and comparison the energy flow in wheat lands of cities in Alborz province. we try to calculate the indexes of energy ratio, gross energy, specific energy, energy efficiency, energy intensity, total input and output energy. population of the study consisted of farmers of cities in Alborz province in the year of 1391-92. It was a best way that we use population Morgan, 273 farmer agriculture Section Alborz Province. To collect the data we can use a questionnaire with reliability coefficient of 0.91 and also Agriculture Organization data. The results showed that, at Between energy input the cultivation of wheat in the 4 district, Chemical fertilizer (28176 MJ/ha) and fuel (22154 MJ/ha) the highest and Human labor (85 MJ/ha) had the lowest energy consumption. This research has a good advantage that we can know Energy ratio in Nazarabad (2.74), Karaj (2.57), Eshtehard (2.23) and Savojblagh (2.5). Nazarabad city with 0.086 kg/MJ and city Eshtehard with 0/070 kg/MJ more in less Energy Productivity among wheat. Among 4 area study city Nazarabad with Net Energy Gain 90802.42 MJ/ha, Energy intensit 5.21 MJ/m2 and Specific Energy 11.57 MJ/kg had better conditions than the other three regions.
