Zengjia Mountain Potatoes

Zengjia Mountain Potatoes are a product with geographical indication status.

　　The potato cultivation in Zengjia Mountain, Chaotian, has a long history and features premium varieties. The main production area of Zengjia Mountain potatoes in Chaotian is located in the national AAAA-level scenic spot — Zengjia Mountain, with an average altitude of over 1,600 meters. Compared to potatoes from typical producing regions, those from Zengjia Mountain have a longer growth cycle, higher starch content, and are grown in a highly “green” environment. They contain significantly more trace elements beneficial to human health, as well as all eight essential amino acids required by the human body. As a project for deep processing of agricultural products, it holds huge market potential. In 2011, Zengjia Mountain potatoes from Chaotian passed the review of the Agricultural Product Quality and Safety Center of the Ministry of Agriculture and expert evaluation, and were registered and protected under the National Agricultural Product Geographical Indication system. This move plays a positive role in leveraging the regional resource advantages of Chaotian, establishing a virtuous mechanism where standardized production is ensured, product quality is guaranteed through labeling, and sales are promoted via branding, thereby increasing agricultural income. Currently, the total planting area of Zengjia Mountain potatoes in Chaotian reaches 400,000 mu, with an annual output of over 500,000 tons, primarily sold to more than 30 large and medium-sized cities including Chengdu and Chongqing, generating significant economic benefits.
