The natural conditions are well-suited for rapeseed production. Located at high latitude and altitude, the region features a cool climate, large diurnal temperature variations, long sunshine hours, and high utilization of effective accumulated temperature, making it highly suitable for the growth and development of rapeseed and conducive to the accumulation of fat in oilseed crops. "Hulunbuir Rapeseed" is characterized by being "high in oil, low in erucic acid, and low in glucosinolates." It enjoys a longstanding reputation in China’s oil industry, with an annual production of 250,000 tons of high-quality rapeseed.
