Abstract:

At present, Chinas edible vegetable oil supply situation is grim, domestic oil production can only provide 40.6% of the total vegetable oil consumption. Oil supply becomes increasingly dependent on foreign countries, security risks become increasingly serious. Rapeseed oil, which is the largest domestic source of edible vegetable oil, has played decisive role in China's edible oil market, and currently accounts for 57.2% of the oil production from oil crops. Therefore, if not competing with grain production, it is a core measure to enhance the rapeseed production potential so as to improve rapeseed yields and protect the safety of Chinas edible vegetable oil supply. This paper overviews the status of Chinas rapeseed production, analyzes the production potential from three aspects of expanding the sowing areas, increasing the yield and improving the oil content, and puts forward suggestions as technological innovation and policy support are effective ways to mine rape production potential.
