With the rapid development of China's agricultural production levels , greenhouse production has become an important part of the agricultural production . Especially cold arid region relatively unfavorable conditions for agricultural production , greenhouse technology is even more important . Temperature the greenhouse technology research object, which is one of the key factors affect crop growth . The greenhouse temperature environment of cold -arid regions , is important to improve the quality and yield of crops . In this paper, the variability of climate cold and dry spring , the first based on LabVIEW data acquisition platform , solar greenhouse temperature environment test test analysis . Second , using Fluent software to numerical simulation of the greenhouse temperature environment . Finally come to simulation and measured values ??are well fitted relationship , the simulation results can reflect the actual changes in the process of the temperature in the greenhouse . Specific test analysis results , the sunny daytime greenhouse temperature change , sooner or later, flatten cloudy throughout the day to flatten evenly distributed . Whether it's sunny or cloudy due to greenhouse levels suck heat uneven temperature distribution in the vertical direction , rendering gradient . By external climate change and the impact of the time change , greenhouse horizontal direction on a sunny day the temperature distribution presents the morning from west to east , central , followed by the phenomenon , the afternoon of the opposite phenomenon ; cloudy evenly distributed , no significant fluctuations in the magnitude . Greenhouse wall , sunny the play store heat during the day , at night to play the role to the low temperature heat release . The cold weather is isolated from the outside world , play a holding role .
