| تعیین عاملهای مؤثر بر زندهمانی، رشد و شادابی درختچههای تاغ (Haloxylon ammodendron (C. A. Mey.) Bge.)ازجمله نیازهای تحقیقاتی در عرصههای تاغکاریشده مناطق بیابانی است. در پژوهش پیشرو، تاغکاریهای منطقه حارثآباد سبزوار در دو عرصه کفبرشده و دستنخورده برای بررسی تأثیر هرس کفبر بر وضعیت اکولوژیک تاغکاریها انتخاب شدند. در هر عرصه شش قطعهنمونه 20 × 20 متری بهصورت منظم- تصادفی با نقطه شروع تصادفی و با فواصل 200 متر از یکدیگر پیاده شدند. در داخل قطعهنمونهها، متغیرهای ارتفاع، قطر تاج، تعداد شاخه فرعی جداشده از یقه و میزان شادابی درختچههای تاغ آماربرداری شدند. همچنین تعداد، ارتفاع و قطر تاج گونههای همراه نیز یادداشت شدند. تجزیه و تحلیل آماری نشان داد که رویش ارتفاعی و قطری و تعداد شاخه فرعی جداشده از یقه در عرصه کفبرشده بهطور معنیداری بیشتر از عرصه دستنخورده بود. تعداد در هکتار و تعداد گونههای زادآوریشده همراه، با وجود زیاد بودن در عرصه کفبرشده، ازنظر آماری تفاوت معنیداری بین دو عرصه نداشتند. همچنین براساس نظرخواهی پرسشنامهای که از ساکنین منطقه برای ارزیابی اثرات محیط زیستی تاغکاریها انجام شد، مشخص شد که این تاغکاریها از جهتهای مختلف، اثرات مثبتی برای ساکنین منطقه حارثآباد داشتهاند. | ||

| The determination of effective parameters on survival, growth and vitality of Haloxylon shrubs is essential for sustainable management of Haloxylon plantations of desert areas. This research aimed to investigate of soil surface height pruning effect on ecological situation of Haloxylon plantations in Hares Abad region of Sabzevar. Six sample plots (20 m × 20 m) were chosen systematic-randomly in two fields (control field and pruned field). In each plot, height, crown diameter, number of secondary branches separated from collar and vitality of Haloxylon shrubs and also number, height and crown diameter of auxiliary regenerated species were measured. The results indicated that annual increment of height and crown diameter and number of secondary branches separated from collar in pruned shrubs were significantly greater than control shrubs. Number of trees in hectare and number of auxiliary regenerated species was also higher in pruned field than control but without significant difference. Furthermore, questionnaires were filled out by regain residents for assessment of environmental impacts of these Haloxylon plantations. The results of this opinion poll showed that Haloxylon plantations have had positive effects for residents of Hares Abad region. | ||
