| چکیده | ||
| به منظور بررسی تاثیر گیاهان پوششی زمستانه و روشهای مدیریت بقایای آنها بر تراکم و وزن خشک علفهای هرز، آزمایشی طی دو سال زراعی 1394-1392 در یک باغ آلو (Prunus domestica) در شهرستان ارومیه اجرا شد. آزمایش با آرایش تیماری کرتهای خرد شده در قالب طرح بلوک‌کامل تصادفی با سه تکرار انجام شد. تیمارها شامل ترکیب چهار گونه گیاه پوششی شامل چاودار Secale cereale))، شبدر ایرانی (Trifolium resupintum)،کلزا (Brassica napus) و‌جو (Hordeum vulgare) در کرتهای اصلی و دو روش مدیریت بقایا شامل استفاده از موور و روتیواتور در کرتهای فرعی بودند. نتایج نشان داد که بیشترین و کمترین‌وزن خشک گیاهان پوششی، به ترتیب به چاودار (275 گرم بر مترمربع) و شبدر (97 گرم بر مترمربع) و نیز بیشترین‌و کمترین‌شاخص سطح برگ گیاهان پوششی، به ترتیب به چاودار (5/3) و شبدر (4/1) تعلق داشت. مقایسه تیمارهای استفاده از روتیواتور و کفبر کردن نشان داد که روتیواتور بهتر از کف بر کردن، تراکم علف‌های‌هرز (67 درصد) و وزن خشک کل علف‌های‌هرز (31 درصد) را کاهش داد. به طور کلی، کاشت چاودار و جو, به همراه استفاده از روتیواتور، بهترین راهکار قابل توصیه برای کنترل علف‌های‌هرز در باغات آلو‌است. | ||

| To investigate the effects of winter cover crops and their management on the density and dry matter of weeds in plum orchards, an experiment was conducted during 2014-2015 in Urmia. The experiment was performed in the randomized complete block design with spilt plot arrangement. Four cover crops in main plots included: ryegrass (Secale cereale L.), barley (Hordeum vulgare L.), oilseed (Brassica napus L.) and clover (Trifolium resupintum L.) and management methods including cutting- off cover crops and using rotivator in sub –plots were experimental treatments. According to the results, the highest and lowest dry matter of cover crops belonged to ryegrass (275 gr.m-2) and clover (97 gr.m-2) and the highest and lowest leaf area index were observed in ryegrass (3.5) and clover (1.4) respectively. Comparison of cutting- off cover crop and rotivator revealed that rotivator’s effect on weed density (%67) and dry matter (%31) is more effective than cutting-off cover crops. Totally, results of this study revealed that ryegrass and barley planting as cover crops, along with using rotivator, is the best recommended method for weed control in Urmia plum orchards. | ||
