盘锦冬季日光温室小气候特征研究

Analysis of Microclimate in Sunlight Greenhouse in Winter in Panjin

为了进一步提高设施农业气象服务水平,对盘锦地区冬季日光温室小气候变化规律进行了分析。结果表明:不同天气条件下日光温室各月气温日变化趋势相似,均呈"单峰"曲线型。晴天和多云天气日光温室内相对湿度昼高夜低;阴天和雨雪天日光温室内相对湿度变化比较平稳。不同天气条件下冬季日光温室室内总辐射最大值出现月份不同,有无草帘对温室内总辐射值影响较大。

To enhance the service of agricultural facilities, the variation law of the microclimate in wintersunlight greenhouse in Panjin Delta was analyzed. The results showed that daily temperature in sunlightgreenhouse varied similarly each month under different weather conditions, showing a‘single peak’curve. Inthe sunlight greenhouse, the relative humidity in sunny and cloudy weather during the day was higher than thatat night, while in overcast and rainy or snowy weather the relative humidity varied relatively steadily. Themaximum of total radiation in sunlight greenhouse under different weather conditions in winter appearedmonthly different. Whether there was a straw matting coating the greenhouse had a great impact on the value ofthe total radiation inside the sunlight greenhouse.
