摘要
为了找出温室内地温变化特点及其与气温变化的相关性,为温室内作物栽培管理及温室结构优化设计提供理论依据。对不同类型温室大棚内地下5、10、15、20cm4种不同深度浅层土壤温度及温室中地上20、50、150cm3种不同高度空气温度进行多点同步观测分析研究。结果表明:随着土壤深度的增加,其温度最高或最低出现的时间逐渐延迟;同时,表层土壤温度变幅远大于深层,即随着土壤深度的增加,土温的变幅将迅速变小;地温与气温变化规律基本一致,但存在一定的滞后现象。
In order to find out the characteristics that the soil temperature changes in the greenhouse and the relativity with atmosphere temperature changes. For the farm crop cultivation and management and the glasshouse structure of excellent turn and design provide a theory basis. Following to carry on more ordering and synchronously prognosticate an analysis research in greenhouse. Observed the four kinds of different depth soil temperatures at 5, 10, 15 and 20 cm in shallow layer and the three kinds of different high air temperatures above the ground 20, 50, 150 cm in different kinds of glasshouses. The results showed that the tallest soil temperature or lowest soil temperature appear delayed gradually along with the increment of the soil depth. At the same time, the changes range of surface layer soil temperature was larger than deep soil temperature, namely the variety range of soil temperature will quickly diminish along with the increment of the soil depth. The change regulation of soil temperature and air temperature was unanimously basic. But the soil temperaturevariety compared with air temperature variety to have to definitely delay a phenomenon.
