Product Characteristics
1. Conical Shape: The most obvious characteristic of the chestnut is its distinct shape from the common chestnut. When viewed from the side, it resembles a cone. In contrast, the common chestnut is larger and has one flat surface, making it easy to distinguish between the two based on their shapes.
2. Regional Specificity: Another feature of the chestnut is its regional specificity. Currently, chestnuts are only found in China, and within China, they are exclusive to the northern regions of Fujian, with Jian'ou being the largest production area.
3. More Suitable for Raw Consumption: The flesh of the chestnut is finer and more delicate than that of the common chestnut. The chestnut contains higher levels of various nutrients and is better suited for raw consumption. It can also be stir-fried with sugar, boiled, cooked into various delicious dishes, or processed into sweets, chestnut flour, chestnut sauce, and various canned goods.
Historical and Folklore
The cultivation history of chestnuts in Qingyuan County dates back to the Qing Dynasty. Farmers referred to them as “iron stalk crops,” an ecologically-friendly economic forest tree species. Qingyuan's mountainous areas were abundant in wild chestnuts, which had long been growing naturally, resulting in low and unstable yields. In the early 1990s, Qingyuan County collaborated with the Asian Forest Research Institute of the Chinese Academy of Forestry. After more than ten years of research and experimentation, five high-quality new chestnut varieties were selected and cultivated. New variety demonstration bases were established, utilizing wild chestnuts for high grafting and promoting non-toxic cultivation management.
