日光温室的温度变化规律研究

Study on Temperature Change Regular of Solar Greenhouse

以西北农林科技大学园艺学院园艺场的西农拱圆型节能日光温室(西农GJ-7型)为研究对象,在冬、春季对室内外不同高度和不同水平位置的气温、地温进行了定时连续多点测定与分析,研究气温、地温的日变化规律及垂直分布和水平分布的动态分布变化情况。结果表明:无论是冬季还是春季室内温度在水平方向上东西、南北方向上的差异不大;而在垂直分布上,冬季室内东部地表以上的温度明显低于中西部;冬季室内温度明显高于室外,室内温度随着室外温度的变化而变化,并且在日出以后室内升温速度明显高于室外;至下午14:00左右达到最高温,之后开始缓慢下降,室内温度下降速度较室外略快;而春季则与之相反。

Taking Xinong arch circular energy-saving solar greenhouse in College of Horticulture Garden of the Northwest Agriculture and Forestry University （Xinong GJ-7） as the research object-in the winter and spring , different heights and different levels of inside and outside air temperature-ground temperature continuous multipoint and timing analysis, the diurnal variation of air temperature, ground temperature and vertical distribution and horizontal distribution of the dynamic change of the distribution were studied. The results showed that there was little difference in horizontal direction and latitudinal direction both in winter and spring inside temperature; and on the vertical distribution, winter inside east surface above the temperature was lower than that of the mid-west. ＇Winter inside temperature significantly higher than the outside and inside temperature changes with the change of outside temperature. Inside temperature was significantly higher than the outside temperature after sunrise. The highest temperature was around 14： 00 in afternoon, and then began to decline slowly, inside temperature decline faster than outside slightly. While the spring by contrast.
