摘　　要：日光温室是北方反季蔬菜生产的重要装备,但目前的日光温室普遍存在成本高、太阳能利用率低及环保性差等缺点。引入泡沫铝作为日光温室的内墙面,研究采用泡沫铝覆盖墙体的温室月度温度变化,同时对典型晴天的温度进行分析,并就甜瓜的生长指标进行表征分析。结果表明,典型晴天时,泡沫铝墙面表面温度较传统的黄土墙面表面温度提高约15℃,温室室内24 h平均温度提高3~4℃。此外,泡沫铝墙面温室内的甜瓜净光合速率较传统黄土墙面温室内的甜瓜提高19.6%。因此,泡沫铝作为蓄热墙体的内侧覆盖材料,能改善温室系统的综合性能,具有成本低、环保性良好等特点。The solar greenhouse is an important equipment for the production of off-season vegetables in the north,but the current solar greenhouses generally have shortcomings such as high cost,low solar energy utilization rate and poor environmental protection.The aluminum foam was introduced as the inner wall of the solar greenhouse,and the monthly temperature changes of the greenhouse covered with aluminum foam were studied.At the same time,the temperature of typical sunny days was also analyzed,and the growth index of melons were characterized.The results showed that in a typical sunny day,the surface temperature of the wall covered with aluminum foam was about 15℃higher than that of the traditional loess covered wall,while the average temperature inside the greenhouse for 24 hours was increased by 3-4℃.In addition,the net photosynthetic rate of melon in the greenhouse with aluminum foam wall was 19.6%higher than that in the traditional loess wall greenhouse.Therefore,as the inner covering material of the heat storage wall,aluminum foams can improve the comprehensive performance of the greenhouse system with the characteristics of low cost and good environmental protection.
