Why is Wen Jun sweet potato sweet?

Geographical location, weather and other reasons.

The main sweet potato producing areas in Wen Jun in western Liaoning are located in Hongluoxian Town, Huangtukan Township, Jiulong Street and other towns in Nanpiao District, Huludao City.

The production area has convenient transportation and extends in all directions. The soil for planting sweet potatoes is brown soil, mostly sloping land, which is rich in various trace elements. Coupled with the microclimate of Huludao, which is dry and rainy, and the temperature difference between day and night is large, melons and vegetables are particularly sweet, and sweet potatoes are a must.
