Ningguo Hickory Nuts

Ningguo Hickory Nuts

Ningguo hickory nuts are a geographical indication certification trademark.

　　Ningguo hickory nuts are characterized by their large size, thin shells, plump kernels, high oil content, and strong market appeal. The city's hickory nut cultivation area now spans 9,300 hectares, with a maximum annual yield of 3,249 tons. With the expansion of hickory nut bases, transportation and processing industries have developed, giving rise to an initial hickory nut processing and sales system. Processed products include salt and pepper, five-spice, cream, multi-flavor hickory nuts, as well as hickory nut kernels and hickory nut oil, forming an industry worth over 100 million yuan. In 1996, Ningguo was awarded the title of “Hometown of Chinese Hickory Nuts.”

　　China’s hickory nuts are mainly distributed along the western Tianmu Mountain range at the border of Anhui and Zhejiang, and are considered a rare and special product. The hickory nut production area of Ningguo is located in the northern foothills of Tianmu Mountain, predominantly in Nanji Township, followed by Wanjia, Zhuangcun, Hule, and other towns and townships, covering a total of 20 townships.

　　Geographic Scope

　　　　　The hickory nut production area of Ningguo is located in the rural areas at the northern foothills of Tianmu Mountain, with the highest concentration in Nanji Township, followed by Wanjia, Zhuangcun, Hule, and others, spanning up to 20 townships within an elevation range of 100–700 meters. High-yield forests are mostly found at mid-to-lower elevations between 300 and 700 meters. The distribution area features majestic, rugged mountains, crisscrossing ravines, and complex terrain, along with a typical mountain microclimate characterized by warm and moist conditions, weak direct sunlight, strong diffused light, hot summers, cold winters, and significant diurnal temperature variations. These conditions are conducive to the growth, fruit development, and nutrient accumulation of the shade-tolerant hickory nut trees. Additionally, Ningguo’s subtropical humid monsoon climate—with coordinated rain and heat, distinct seasonal cycles, mild temperatures, and clearly defined four seasons—fully meets the climatic requirements for hickory nuts. The superior soil and vegetation conditions in Ningguo’s hickory nut distribution zones provide a solid foundation for the excellent quality of the nuts.

　　Distinctive Qualities

　　Cultural Stories

　　　　　　According to fossil research, hickory nuts were present in East China as far back as 40 to 25 million years ago during the Oligocene epoch of the Tertiary period. By the Miocene epoch, hickory nuts, along with certain species from the Betulaceae and Fagaceae families, had become major components of the subtropical deciduous–evergreen broadleaf mixed forests in East China. Later, due to the devastation of the Quaternary glaciers, they survived only in the Tianmu Mountain region at the border of Anhui and Zhejiang, making them one of the ancient relict tree species. As the main producing area of hickory nuts in the Tianmu Mountain range, Ningguo has long enjoyed a prestigious reputation for its hickory nuts. As early as the 28th year of the Jiajing reign during the Qing Dynasty, the “Ningguo County Annals” recorded: “Ningguo has many mountains that produce hickory nuts. When the nuts are young and unshelled, they resemble peaches, hence the name.” “When White Dew arrives, the bamboo poles sway; golden nuts cover the ground, carried on shoulder poles.” Our province’s Ningguo is the hometown of hickory nuts, and every year during the White Dew season marks the start of the hickory nut harvest.
