| چکیده | ||
| گیاهان طی عمل فتوسنتز، کربن معدنی، اتمسفر را در زیست تودة خود ترسیب می کنند که این کربن در نهایت از طریق بقایای گیاهی در خاک ذخیره می‌شوند. این پژوهش به‌منظور اندازه‌گیری میزان کرین آلی ترسیب‌شده در بخش‌های مختلف گیاهان، اندازه‌گیری میزان تصاعد گازهای کربنه هر کاربری و در نهایت محاسبة بیلان کربن آلی صورت گرفت. منطقة مورد مطالعه، دارای سه کاربری کشاورزی (گندم، کلزا، باقلا و یونجه)، مرتع و نخلستان می‌باشد که از هر کاربری 5 نمونة گیاهی با کوادرات با ابعاد 1×1 متر برداشت گردید. نمونه‌ها آسیاب و درصد کربن کل زیستتودة گیاهی و هر بخش از گیاه (ساقه، برگ و ریشه) محاسبه گردید. میزان گازهای متصاعد شده از سطح خاک نیز توسط اتاقک بسته اندازه‌گیری گردید. نتایج نشان داد که درصد کربن در کل زیست تودة گیاهی کاربری‌ها در سطح اطمینان 99 درصد معنی‌دار بود. به‌طوری که میانگین درصد کربن در کلزا، گندم و باقلا بیشترین و در گیاهان مرتعی و گیاهان زیر کشت نخل کمترین مقدار بود. همچنین، مقایسة آماری کربن در بخش‌های مختلف گیاهان (ساقه، برگ و ریشه) در هر کاربری بر اساس طرح فاکتوریل بر پایة بلوک کاملاً تصادفی با 2 تکرار در محیط نرمافزار SAS اجرا شد. نتایج نشان داد که بیشترین درصد کربن به‌ترتیب در ساقه، ریشه و برگ گیاهان هر کاربری وجود داشت و بیلان کربن آلی در کاربری کشاورزی بیشترین و در کاربری مرتع کمترین مقدار بود. | ||

| چکیده [English] | ||
| During photosynthesis, plants secrete atmospheric mineral carbon into their biomass, which is eventually stored in the soil through plant debris. It was used and finally the organic carbon balance was calculated. The area has three land uses, including agriculture (wheat, canola, beans and alfalfa), pasture and palm grove. From each land use, 5 plant samples in quadrats with dimensions of 1m ×1m were taken. Samples were milled and the percentage of carbon in the total plant biomass and each part of the plants (stem, leaf, and root) was calculated. The amount of gases emitted from the soil surface was also measured by a closed chamber. The results showed that the percentage of carbon in the total plant biomass of the studied land uses is significant at 99% confidence level, so that the average percentage of carbon in rapeseed, wheat and beans is the highest and in rangeland and palm crops is the lowest. Also, the percentage of carbon in different parts of plants (stem, leaf, and root) in each cultivation was performed according to a factorial experiment based on a completely randomized block design with 2 replications in SAS software. The results showed that the highest percentage of carbon was present in the stems, roots and leaves of the plants of each use, and the organic carbon balance was the highest in the agricultural use and the lowest in the pasture land use. | ||
