[Abstract]:The aim of this paper is to optimize the wall structure of the Gobi in Xinjiang, and the main research object is the wall in the solar greenhouse of the Gobi in Xinjiang. Based on the low limit thermal resistance of solar greenhouse and the simulation and prediction software of wall heat storage capacity of solar greenhouse, the wall structure design and calculation of Gobi greenhouse is carried out to form the optimum wall combination scheme of solar greenhouse in Gobi area of Xinjiang. The optimal model of material and environment control should be set up to promote the design of solar greenhouse, the development of theory and method of construction, and the enhancement of the ability of sustainable development of facility agriculture. The main research contents of this paper are as follows: (1) in view of the unique ecological and natural environment characteristics of Gobi area, we compare the wall materials suitable for the Gobi solar greenhouse. Collect and sort out the dry bulk density and thermal conductivity of the common greenhouse heat storage materials and thermal insulation building materials in Xinjiang from the aspects of wall bearing support and thermal insulation and heat storage. To provide reliable numerical value for wall combination calculation of Gobi greenhouse in Xinjiang, aiming at the combination mode of different thickness and material of five kinds of practical multi-layer wall in Xinjiang. Introducing and referring to the design idea of the thermal resistance of wall materials in the greenhouse Standard: JB / T 10286-2001 "Solar greenhouse structure", a total of 403 kinds of multi-layer walls of five categories with strong practicability are combined with different thickness and different materials. Based on the key open laboratory of the Ministry of Agriculture of China Agricultural University, the heat storage and heat preservation performance simulation software of RGWSQCR solar greenhouse wall is developed and designed. Seven kinds of greenhouse with different wall combination structure suitable for production greenhouse in Kezilesu Kirgiz Autonomous Prefecture, Xinjiang, are put forward to simulate the average heat release per unit area and the total amount of accumulated heat release, and to simulate the change of indoor environment day and night. By simulating the variation of wall heat release with time in greenhouse at night, the paper compares the heat preservation performance difference of 7 kinds of representative structure wall with that of Gobi greenhouse with four kinds of wall structures that have been built and used, through testing the lowest and highest temperature in time. The average value and continuous diurnal variation are compared between the different wall and the influence of different walls on the greenhouse microclimate environment, and the best greenhouse wall structure scheme of greenhouse thermal performance is obtained. In this paper, through the combination calculation of wall structure in Gobi greenhouse, simulation test and analysis of measured data, it is concluded that the outdoor design temperature of greenhouse in Xinjiang is -5 鈩，
