Abstract: In cold winter area，cost of solar greenhouse heating is an important factor to determine cost of greenhouse operation.Characteristics of greenhouse heating technology of the heating system of hot blast stove and water heating stove with lower cost were discussed.A heating system of hot blast and water heating integrated stove was designed by combining two technologies.The system could make good use of combustion heat in furnace，and have a variety of heating and cooling forms，expand heating area，improve temperature in the greenhouse，which provides an effective and feasible technical choice for heating technology and equipment in winter in solar greenhouse.
