Abstract: The structure and performance of the rear roof have a great influence on the performance of the solar greenhouse. To design the most suitable rear roof of greenhouse in Yantai city, by investigating the solar greenhouses and its rear roof structure used in conventional production and with the help of the solar greenhouse light environment simulation software developed by China Agricultural University, taking back roof inclination, horizontal projection width and the structure of back roof as the independent variable, simulate and study different roof after the influence of parameters on the temperature inside the greenhouse. According to the simulation calculation, in the case of 9 m span of solar greenhouse, the optimized parameters of the back roof were inclination angle of 38°, horizontal projection width of 1.3 m, and the composite structure material should use extruded board instrad of polystyrene board.

Key words: solar greenhouse, rear roof, parameter, optimization, Yantai city
