The soil in the ecological sand region seriously degenerated in
Luanhe River Basin. Improvement of the economic benifit of
winter wheat is useful for enlarging the grown area of winter wheat and managing sand soil. The rational fertilizer technology is one of the available measure for improving the income of winter wheat in this
ecological sand region. An experiment on the soil nuteient resteictive factors and high yielding high effective fertilizer applecation was conducted in Luanxian County Experiment Region of Hebei province from 1997 to 1990. The result showed that in the ecological sand region near
Luanhe River Basin, nitrogen and potassium were restrictive factors of winter wheat yield. The restricting effects on winter wheat yield were N>K 2O.The single application of N for best result was 297.60~313.65 kg/hm 2, and 170.7~178.95 kg/hm 2 for K 2O. When 30 t/hm 2 organic fertilizer was added, the application of N was 293.40~312.75 kg/hm 2, and 151.50~159.15 kg/hm 2 for K 2O application.
