| چکیده | ||
| چرای دام عمومی‌ترین نوع کاربری مراتع بوده و می‌تواند بر ترکیب پوشش گیاهی مرتع، تولید خالص اولیه، نسبت اندام هوایی به ریشه و چرخه عناصر غذایی موثر باشد. پژوهش حاضر با هدف بررسی تأثیر شدت‌های مختلف چرای دام بر تخصیص عناصر غذایی فسفر، کلسیم، سدیم و پتاسیم در اندام‌های هوایی و زیرزمینی Artemisia aucheri در مراتع ییلاقی دامنه جنوب شرقی سبلان انجام شد. در این پژوهش از نمونه‌برداری تصادفی-سیستماتیک استفاده شد. در هر شدت چرایی 3 ترانسکت 200 متری به‌صورت موازی با یکدیگر مستقر شدند. سپس در امتداد هر ترانسکت پلات‌های یک مترمربعی به فواصل 50 متر مستقر شد. در هرپلات، نمونه‌برداری از اندام‌های هوایی و زیرزمینی صورت گرفت. نتایج تجزیه واریانس تخصیص عناصر غذایی مورد بررسی در گونه A.aucheri نشان داد که فسفر و کلسیم اندام‌های هوایی در سطح پنج درصد تحت تأثیر شدت‌های مختلف چرایی قرار گرفتند. همچنین سدیم و کلسیم اندام‌های زیرزمینی در سطح یک درصد دارای اختلاف معنی‌داری بودند. نتایج این تحقیق و ارتباط بین تخصیص عناصر غذایی و چرای دام، می‌تواند در شناخت و مدیریت چرای دام و مرتع بکار رود. | ||

| چکیده [English] | ||
| Livestock grazing is the most common type of rangeland uses that can affect the composition of rangeland vegetation, net primary production, stem to root ratio, and nutrient cycle. This research was conducted to study the impacts of various grazing intensities on nutrient allocation of phosphorus, calcium, sodium, and potassium in aerial and underground biomass of Artemisia aucheri in the summer rangelands on the southeast slope of the Sabalan. In this study, a systematic-random sampling was employed. Three parallel transects of 200 m length were established in each grazing intensity. Then along each transect, one square meter plots with 50 m intervals were established to collect the aerial and underground biomass. Analysis of variance revealed that the allocation of phosphorus and calcium of the aerial organs were significantly affected by different grazing intensities. In addition, sodium and calcium of underground organs were significantly different at 1% level. The results of this research and the effect of different grazing intensities on nutrient allocation could be used in the identification and management of livestock grazing and rangelands. | ||
