Tongzi Broad Beans

Tongzi Broad Beans

　　Broad Beans

　　These broad beans are grown in the Qingba Mountains of Tongzi County, distributed across altitudes between 1,350 and 1,500 meters. This area lies on the edge of the primeval forest zone, featuring a cool climate and moderately fertile soil — conditions ideal for broad bean cultivation. The Qingba region has a nearly century-long history of growing broad beans. As a specialty of Zunyi region, these beans were exhibited at the National Agricultural Exhibition in 1957 and exported overseas.

　　The broad beans come in two varieties: white and mixed-color. The white beans are smooth and glistening, resembling jade, while the mixed-color beans feature alternating purple-red and black hues. Tongzi broad beans are distinguished by their thick cotyledons, large size, kidney-like shape, and average weight of around 10 grams. Rich in starch, protein, essential trace elements, and dietary fiber needed by the human body, they offer high nutritional value and are often served at state banquets. They are also considered one of the ideal health and fitness foods.

　　Qingba in Tongzi County has long been renowned for producing broad beans, with peak annual output reaching approximately 20,000 kilograms. However, production has declined year by year in subsequent decades, and in recent years, the average annual yield has generally stabilized at around 5,000 kilograms. Currently, market demand is urgent. To further develop this local specialty, strict seed selection and breeding should be implemented, along with expanded planting areas to gradually restore and increase yields.
