After 1997-2002 research and demonstration on the northward migration of winter wheat and wheat in the Yellow River Diversion Irrigation Area, the applied area has reached 71,800 hectares. The winter wheat has been planted in large area in pure spring wheat area with an average yield of 376.9kg, Compared with the spring wheat yield 39.3kg, an increase of 11.6%, the normal year yield more than 400kg, winter wheat cultivation and sets of double cropping system is basically mature, the use of winter wheat mature harvest fully tap sets of complex grain, oil, feed, Vegetables and other crops to increase production potential, and achieved significant economic, social and ecological benefits.
