According to the prominent problems of the incoordination between fertilizer inputs and outputs in winter potato production in Yanshan District, demonstration trials of fertigation were conducted. The experiment results showed that yield of drip irrigation plus 40 % regular fertilization is 30.38 % higher than regular fertilization and 29.76 % higher than drip irrigation plus 100 % regular fertilization（yield increased 497kg）. Application of fertigation on winter potatoes received very good effect.
