Received: 25 December 2017 Accepted: 15 June 2018 In light of the great soil wall sizes of solar green houses and the low land utilization rate of solar greenhouses in China, this paper carries out a temperature field experiment in a solar greenhouse in order to understand the distribution of temperature field in the greenhouses in Central Hebei region. On the basis of the experiment, this paper establishes a numerical model of the temperature field in the solar greenhouse using the CFD software, and optimizes the wall structure of the greenhouse by the numerical simulation of different heights and thicknesses. The results can provide technical reference for the construction of new-type energy-saving solar greenhouses.
