| 摘要 | With brick-wall solar greenhouses in Changli area as the research object, using temperature dynamic monitoring and statistical methods, the greenhouse structure suitable for promoting early cultivation of local peach trees was selected by studying the temperature data of the solar greenhouses during the winter solstice, and a prediction model for daily average temperature was constructed. The results showed that greenhouse I had reasonable structural parameters and good daylight during the day. However, due to the low wall thickness and poor insulation material, the minimum temperature was significantly lower than other greenhouses. The thermal insulation performance of greenhouse Ⅱ and Ⅲ was better than that of greenhouse Ⅰ, but the depth-span ratio and the front roof lighting angle were smaller. During the winter solstice, the average temperature of the three greenhouses was between 10 and 15℃, which was suitable for early cultivation of peach trees. The prediction model of daily average temperature was obtained: Daily average temperature =1.02+ 0.69× Daily average temperature of the previous day + 0.02× Maximum temperature of the previous day -0.01× Minimum temperature of the previous day. To sum up, the structural parameters of brick-wall solar greenhouses suitable for early cultivation of peach trees in Changli area were as follows: span 6.5 m-8.5 m, depth-span ratio 0.47, front roof lighting angle 30° and wall thickness greater than 55 cm. |
