Jiangjiabu Scallions

Jiangjiabu scallions are a product with a geographical indication.

　　Jiangjiabu scallions have a long cultivation history. During the Ming Dynasty, they were widely grown along the west bank of the Dagushui River (now including areas such as Guxian, Renzhao, and Nancun). In 1552 AD, the scallions were honored by Emperor Shizong of the Ming Dynasty as the "King of Scallions." They are also mentioned multiple times in the 1987 "Pingdu County Annals." Among the many varieties of scallions in China, Jiangjiabu scallions embody the three qualities of being "famous," "special," and "premium." Currently, the annual planting area of Jiangjiabu scallions in the region exceeds 25,000 mu, with a total output of 180,000 tons and an annual output value of over 300 million yuan, primarily featuring the Qianye Guangcai variety. Jiangjiabu scallions are uniformly long and straight, with consistent thickness, bright green leaves, firm milky-white stalks, a compact texture, mildly spicy and slightly sweet flavor, and good storability. In 2007, the Jiangjiabu brand vegetables were recognized as a Famous Trademark of Qingdao City, and in 2011, they were awarded the title of Famous Trademark of Shandong Province.

　　In recent years, to promote the branded development of Jiangjiabu scallions, Nancun Town has established a pesticide-free scallion production base covering a total area of 25,000 mu, with an annual output of 180,000 tons and an output value exceeding 300 million yuan. Within the base, scallion production strictly follows pesticide-free food standards to ensure product quality and safety.

　　The certification of "Geographical Indication Product Protection" will effectively enhance the market competitiveness of Jiangjiabu scallions.

　　It is understood that the total planting area of scallions in Pingdu is about 10,000 mu, with over 5,000 mu planted around Jiangjiabu Village in Nancun Town alone, making it a veritable scallion village. Unlike surrounding villages, through standardized production, the quality of the cultivated vegetables is excellent. Not only has the "Jiangjiabu" brand vegetable trademark been registered, but it has also been recognized as a Famous Trademark of Qingdao City.
