吐鲁番日光温室冬季温度变化规律及保温性研究

Study on the Winter Temperature Change Rule and Heat Preservation Performance in Solar Greenhouse in Turpan

以吐鲁番地区日光温室为研究对象,针对日光温室的保温性能,研究冬季温室温度变化规律,以期为设施葡萄栽培提供适宜的生长环境,为提高温室保温性能提供理论依据。结果表明:吐鲁番日光温室内的温度随着温室外温度变化而变化,散热比较快的位置是温室的前坡及中间的棚膜处,而三面墙体相比较,温室入口处的温度变化速率最大,热散失最快,后坡墙体温度保持最好,热散失相对较慢。

The solar greenhouse in Turpan was taken as research object,the heat preservation performance of solar greenhouse was studied to reveal the temperature change rules of greenhouse in the winter,in order to provide appropriate environment for facilities viticulture,provide theoretical basis for improving heat preservation performance of greenhouse.The results showed that the greenhouse temperature changed along with that of the outside,in the middle of the film and scarp slope of greenhouse heat dissipation was faster,and three sides wall compared,at the entrance of greenhouse temperature change rate was the largest,heat dissipation was the fastest,the backwall temperature maintained was the best,the heat dissipation was slower relatively.
