Guyuan Flax

Guyuan Flax

　　Guyuan County has historically been an oilseed production area, once hailed as Ningxia’s “oil basin.” Its representative crop, flaxseed, boasts a high oil content, excellent quality, high value, wide applications, abundant resources, and great potential. The main varieties are Ningya No. 10 and Ningya No. 11, with an annual planting area of around 200,000 mu and a total output of over 12 million kilograms, accounting for about 25% of Ningxia’s total oilseed production. A regionalized variety layout, standardized cultivation, serialized services, and scaled-up production have been established. Among them, Ningya No. 10 is an early-maturing, large-seed oil-type variety, with a thousand-kernel weight of 9.0–10.2 grams, an oil content of 41.8%, and an oil extraction rate of 32.3%; Ningya No. 11 is an oil-and-fiber dual-purpose variety, with an oil content of 43.3% and an oil extraction rate of 35.3%. The oil is pure, fragrant, and has a pleasant taste and flavor, making it an ideal edible oil. The straw can be used in linen production and papermaking, while the oil residue serves as a fertilizer for soil enrichment and as a feed additive for livestock and poultry fattening.
