Enjoyed by the delicious taste of Kuancheng chestnut, Japanese scientists once transplanted it to Japan. Unexpectedly, "the orange grows in Huainan and becomes tangerine, and the orange grows in Huaibei and becomes tangerine." In fact, Japanese scientists do not know that even in areas close to Kuancheng, the chestnuts produced are very different from those in Kuancheng.

So, why is Kuancheng chestnut so magical?

Chestnuts are produced in quite a few countries and regions in the world. Some are called oil chestnuts and some are called hair chestnuts. It can be said that they are widely distributed and come in many varieties.

Kuancheng chestnut cultivation has a long history. "Lü's Spring and Autumn Annals" records that "the three beauties of state-owned chestnuts include chestnuts from Jishan". Sima Qian of the Western Han Dynasty has a clear record in the "Biography of Huozhi" in "Historical Records" that "Yan, Qin Qianshuli? These people are all the same as Qianhuhou". There is a saying in "The Biography of Su Qin" that "Qin said that Marquis Yan Wen said: There are Jieshi and Yanmen in the south, and there are jujubes in the north. Although the people do not work carefully, they are content with jujubes. This is the so-called Tianfu." Lu Ji of the Western Jin Dynasty also wrote annotations for "The Book of Songs": "Chestnuts are found in all five directions, but those born in Yuyang and Fanyang are sweet and delicious, and they are not as good as those in other places." In the above records, "Jishan", "Bei", and "Yan" are "The place mainly refers to the Yanshan area where Kuancheng is now located. The above records prove that Kuancheng, located in the Yanshan Mountains, has a very long history of chestnut cultivation and is an important origin of chestnut cultivation technology in my country.

Chestnut has strong drought resistance, is less affected by climate change, and is called a hardcore crop by locals because of its hardness. In ancient times, chestnuts were enough to ensure a prosperous life for the people. The amount of chestnut planted was once an important symbol of social status at that time.

Kuancheng chestnuts are delicious, and people are not making them up. Although there are elements of artificial cultivation, it is mainly derived from nature. From a scientific perspective, the quality of a product has a great relationship with the local climate, precipitation, and soil. Kuancheng has the best conditions for chestnut growth.

Here is the most suitable land for chestnut growth. The surface layer of Kuancheng Mountain is an easily weathered gneiss with a loose structure, high iron content, slightly acidic reaction, and good ventilation and water permeability, which provides excellent site conditions for chestnut growth.

Here is the most suitable rainfall for chestnut growth. The terrain of Kuancheng is on the windward side of the southeast monsoon, with annual precipitation of about 800 mm. The rainy season is mostly concentrated in July and August. The precipitation cycle just meets the water demand of chestnut fruits during their rapid growth period.

Here is the most suitable temperature for chestnut growth. Kuancheng has a large temperature difference between day and night, with temperatures high during the day and low at night, which is conducive to photosynthesis and sugar accumulation in fruits. There is ample sunshine here, with a frost-free period of 183 days a year. It is beneficial to the growth of chestnut trees, the development of chestnut fruits, the transformation and accumulation of sugar, fat and various organic acids inside the chestnut fruits, and also provides an important guarantee for the external coloring of the fruits.

Of course, there is a more important point, that is, in 2008, the Kuancheng County Government suggested that Hengtai Group invest in a chestnut deep processing project and established Shenli Food Company.

Shenli Company spent more than 9 years researching with the Chinese Academy of Agricultural Sciences and China Agricultural University to cultivate chestnut varieties "Dabanhong", "Yanjin" and "Yanjin" that are only recognized in the soil of Kuancheng. Yan Kuan", Xiong 84, etc. And invested in the establishment of the China Chestnut Industry Research Center. At the same time, the circular economy under the trees is promoted. By using discarded chestnut branches to cultivate chestnut mushrooms, free-range poultry, and plant Chinese medicinal materials under the trees, net income can be directly increased by about 5,000 yuan per mu. The increase in economic income and the improvement of people's lives in Kuancheng have promoted the improvement of social order and the harmony of the social environment.
