寒冷干旱地区温室温度的测试分析

温度是影响作物生长的关键因素之一,是衡量农业生产水平的重要技术参数。为此,试验基于Lab-VIEW数据采集平台,针对寒冷干旱地区,对不同气候变化下的温室温度进行测试、采集数据,实现了温室内多点温度的实时采集;并在采集数据的基础上,分析了温室内温度分布规律。试验结果表明:无论是晴天还是阴天由于覆盖层、空气和土壤的吸散热不均匀,垂直方向上各层面的温度分布呈现梯度;晴天白天温室内温度变化剧烈,而夜晚趋于平缓;上午西侧空气温度比东侧高,下午则相反;阴天水平方向上的温度呈现南低北高,东西低中间高的分布趋势。

Test and Analysis of Greenhouse Temperature of Cold-arid Areas

Temperature is an important factor of plants growth and a technically measurable parameter of agricultural production-level.Based on LabVIEW that it is a powerful data processing software,this research focusing on cold-arid areas acquired and collected all kinds of temperature information of greenhouse in most weathers.It is a real-time system did the analysis of temperature distribution rules as well as testing.The result showed whether it is sunny or cloudy,as the different heat absorption of the cover,air and soil,the temperature at vertical level shows gradient distribution.On sunny days,the temperature changes sharply in the greenhouse and at night it becomes slow.In the morning,the west side of the air temperature is higher than the east,until the afternoon.On cloudy days the horizontal temperature has a trend that the south temperature is lower than the north.And the middle temperature is higher than the east and west ones.
