Abstract:: In order to optimize new structure of non-cultivated land greenhouse in Ningxia，explore fuel-efficient way to produce horticultural crops,through changing the walkway of traditional greenhouse from north to south，sinking planting area 95 cm，building the structure of new greenhouse by whole assembly galvanized steel frame，and configuring geothermal system and supplemental lighting system，to complete the design and construction of non-cultivated land new greenhouse that span 13.4 m.The results showed that the new greenhouse with geothermal system and supplemental lighting system daily air temperature increased 1.36℃ and ground temperature increased 1.66℃ compared with contrast greenhouse，and the light environment of horticultural crops growth could be improved in the winter，at the same time the new greenhouse had good heat preservation,convenient construction,long service life,and the advantages of low maintenance cost.
