"Hulunbeier Rapeseed" production area is concentrated in Daxinganling and the transitional area between forest and grassland in the west of Lingxi, and natural conditions are suitable for developing rapeseed production. Located at high latitude, high altitude, cool climate, large temperature difference between day and night, long sunshine time and high utilization rate of effective accumulated temperature, it is very suitable for the growth and development of rapeseed and is beneficial to the accumulation of fat in oil crops. Hulunbeier rapeseed has the characteristics of high oil, low erucic acid and low glucosinolate. Hulunbeier rapeseed enjoys a long-standing reputation in the national oil industry, with an annual output of 25, tons of high-quality rapeseed.
