【摘要】 利用2013年12月—2015年2月章丘双屋面日光温室内小气候观测资料,对冬、春季阳屋面温室内气温、湿度的季节变化特性及不同天气类型下的日变化规律进行分析,并与传统日光温室进行比较。结果表明:冬、春季阳屋面温室内最高气温变化幅度均较大,但均未出现10℃以下的低温,春季易出现35℃以上的高温天气,最低气温较传统日光温室高1℃左右;冬、春季不同天气类型下阳屋面温室内气温日变化均呈"单峰型"曲线,温室内日最高气温和日最低气温均为:晴天>多云天>阴天,冬季分别出现在13时和7时,而春季日最高气温推迟1小时,日最低气温提前一小时;冬、春季阴天时阳屋面温室内日最大相对湿度均较传统日光温室高10%以上。阳屋面温室蓄热、保温性能更好,对喜温蔬菜作物生长有利,但高湿环境使作物病害风险提高。本研究对阳屋面温室内气温、湿度季节特征及日变化规律进行系统分析,为今后双屋面日光温室在北方地区的推广应用提供理论依据。更多还原

【Abstract】 The analysis and comparing with the traditional solar greenhouse on seasonal variation characteristics in Winter and Spring and the daily variation rule under different weather types of air temperature and humidity in greenhouse toward the sun by using the microclimate data from December 2013 to February 2015 in Zhang Qiu double roof greenhouse. The results showed that the highest air temperature in greenhouse toward the sun changed largely in Winter and Spring, and no low air temperature under 10℃ appeared. The highest air temperature above 35℃ appeared frequently, and the lowest air temperature was lower 1℃ than the traditional greenhouse in Spring. The daily variation rule under different weather types of air temperature in greenhouse toward the sun presented ‘Single-peak’ curve in Winter and Spring, and The highest and the lowest air temperature showed that: sunny > cloudy >cloudy day. The highest and the lowest air temperature in greenhouse toward the sun appeared separately in 13 and 7 in Winter. The highest air temperature in Spring delayed 1 hour, and the lowest air temperature in Spring advanced 1 hour. The highest humidity in greenhouse toward the sun was higher 10% than the traditional greenhouse in Winter and Spring when cloudy day. The greenhouse toward the sun could absorb more heat and keep warm, and was good for thermophilic vegetable, but the disease risk in the high humidity environment. This study systemly analysised the seasonal variation characteristics and the daily variation rule of air temperature and humidity, and provided theoretical basis for the future application of the double roof greenhouse in the northern region in China.更多还原
