Ha Yuan Potatoes

Ha Yuan Potatoes

Ha Yuan Potatoes is a geographical indication product for agricultural produce.

　　Ha Yuan Potatoes

　　Ha Yuan County is situated in the mountainous region of southern Ningxia and has a typical continental monsoon climate with short frost-free periods, frequent winds, and little rainfall. The soil is mainly black loessial soil, which is rich in potassium ions, deep, and loose—making it excellent for potato cultivation. The potato planting area has been continuously expanding, and the diversity of varieties has increased. It is also a crop suitable for drought resistance and disaster mitigation. The main potato-producing areas are concentrated in the hilly and gully dryland late-maturing regions of the Loess Plateau formed by the Moon Mountain and South Mountain ranges in the central and southern parts, as well as the early-maturing irrigated areas along the Yellow River in the north. With the strategic structural adjustment of the rural economy, our county has designated the three townships of Xinglong, Liwang, and Gaoya in the Yellow River Diversion Irrigation Zone as bases for producing vegetable-type potatoes. The three townships of Xingren, Xutao, and Songchuan in the arid northern belt have been designated as bases for producing dual-purpose grain-and-vegetable-type potatoes, while the cool-climate areas of twelve townships in the central and southern regions have been identified as bases for starch-type potato production. In addition to focusing on improving both the yield and quality of potatoes, we are actively cultivating breeding bases and establishing processing and sales enterprises to foster a new development pattern for the local potato industry. To build the second-largest potato production base in Ningxia, following the principles of “expanding planting area, improving quality, increasing per-unit yield, and boosting benefits,” we are providing strong support in terms of policy, funding, and technology. We are prioritizing the construction of two potato industrial belts: the southern starch-type potato industrial belt and the central starch-and-vegetable-type potato industrial belt.
