摘　　要：为研究阴阳结合型日光温室内环境特征,用PC-3型自动气象站分别对阴、阳棚内的太阳辐射量、空气温湿度、土壤温度及共用墙体热通量进行测试。结果表明:在整个测试期间阳棚≥5℃、≥10℃的积温分别为1 898.6℃、1 783.8℃,阴棚≥5℃、≥10℃的积温分别为839.8℃、338.1℃;阳棚平均气温、太阳辐射量较阴棚增加了8.4℃、6.95 MJ;阳棚5 cm、10cm、15 cm土层的土壤温度比阴棚分别升高8.7℃、9.1℃、9.5℃;阳棚空气湿度比阴棚降低了10.3%;阳棚墙体和地面吸热量和吸热时间高于阴棚,而放热量及放热时间低于阴棚。To investigate the intra-environmental characteristics of combining light with shade solar greenhouse, PC-3 automatic weather station was used to measure solar radiation, air temperature and humidity, soil temperature and the shared wall heat flux in this study. The results showed that during the whole test, accumulated temperature of ≥5 ℃ and ≥10℃ of sunlight-side was 1 898.6 ℃ and 1 783.8 ℃ respectively, accumulated temperature of ≥5 ℃ and ≥10 ℃ of cool-side was 839.8 ℃ and 338.1 ℃ respectively. Average temperature of sunlight-side increased by 8.4 ℃ than that of cool-side, solar radiation increased by 6.95 MJ than that of the cool-side. Soil temperature with depth of 5 cm, 10 cm and 15 cm in the sunlight-side was 8.7 ℃, 9.1 ℃, 9.5 ℃ respectively higher than that of the cool-side in the greenhouse. Air humidity in the cool-side was 10.3% lower than that of the sunlight-side in the greenhouse. Heat absorption and time of walls and soil surface in sunlight-side were higher than that of the cool-side, while heat output and time in the sunlight-side were lower than that of the cool-side in the greenhouse.
