Abstract In 2012，investigation was conducted on farmer’s solar greenhouse cultivation modes and their benefits in 498 households，43 villages，25 townships of Wuwei City，Gansu Province．The results showed that crops cultivated in greenhouse of Wuwei City were mainly cucumber，tomato，pepper and other fruits and vegetables．The main cultivation rotation model was one year one crop and the next mode was two crops a year．Production costs including plastic film，straw，seedling，fertilizer accounted for about 82.4% of the total cost．Input-output rate and the average single water benefits of both one year one crop and two crops a year rotations were higher．The main limiting factor of perennial cultivation was low yield．Therefore，considering the input-output rate and local water resource situation，we suggest to develop the mode with more crops cultivation per year in the central area of Wuwei City，and perennial cultivation mode in the townships in cool irrigation area and Eyinshan district with altitude above 1 500 m．
