دليل B2B لأرز صدري دم‌سیاه أستانه — مقارنات وفرز وبنكدارة.
البيئة الزراعية ورقم صدري دم‌سیاه
أرز صدري دم‌سیاه من أرفع الأصناف المحلية في شمال إيران؛ منشأه الأمثل دلتا نهر سفيدرود في أستانه أشرفية. مياه النهر والتربة الطميية والرطوبة الساحلية تعزز مركبات العطر والنشا في البذرة.
الخصلات السوداء الطويلة على القشة الذهبية أعطت الاسم. طول الحبة الخام ٧–٧٫٥ مم وطول الطهي ١٢–١٦ مم مع ثبات نعومة استثنائي؛ محدودية الإنتاج ترفع السعر الفاخر.

Market structure & risks
A three-tier network spans village mills (Lesko Kolaye, Kisam), mid-tier sorting complexes and urban brokers on Sardar Jangal and Beheshti streets; the county guild sets conversion fees and discipline.
Key risk: bulk blending — NIR inspection, genetic certificates and sealed traceable packs are required.
Contract farming (e.g. Gildeh cooperative) and premium buy-back are vital to keep Dem-Siah in the field.
Export outlook
Persian Gulf, Central Asia and EU diaspora channels match Basmati-like cooking behaviour. PGI registration for “Astaneh Ashrafieh Gilan Dem-Siah rice”, international MRL compliance and MAP packing in Nogreh Deh anchor sustainable value capture.
