摘要： 在日光温室冬季栽培条件下,利用温室智能监控系统,自动监测记录温室内外空气温度、光照强度、空气湿度,温室内co2浓度、土壤温度、土壤水分,研究各环境因子日变化规律及温室内环境因子与外界环境因子关系。结果表明,温室内外各环境因子间日变化联系紧密；除土壤温度和土壤水分外,其它各环境因子彼此之间都具有极显著相关性；温室内外光照、温室内外温度彼此之间呈极显著正相关,曲线呈不规则的“n”形,并与温室内外湿度、温室内二氧化碳浓度呈极显著负相关,日变化呈不规则的“u”形；土壤水分日变化较小,有一个趋同土壤温度变化的微弱变化；温室内环境变化与温室外环境变化联系紧密,温室内温度变化是温室外温光条件共同影响的结果,土壤温度受外界环境温度影响最大,温室内光照与温室外光照紧密联系。

Abstract: In order to get the characteristics and regulation of environmental factors and the interaction of inside-outside environmental factors in greenhouse in the winter, the greenhouse intelligent control system was used to record and store the data of indoor co2 concentration, soil temperature, soil moisture, indoor and outdoor temperature, humidity, light. the results showed that the interaction of environmental factors was close; except soil temperature and soil water ,environmental factors had a significant correlation between each other; temperature and light of inside-outside greenhouse had a significant positive correlation between each other, curves were irregular "n" shape, humidity of inside-outside greenhouse and co2 concentration of inside greenhouse had a significant negative correlation with them, curves were irregular "u" shape; soil moisture had a smaller diurnal variation, it had a close interaction with soil temperature; environmental factors of inside-outside greenhouse had a close interaction, the temperature change of inside greenhouse was the results of the combined effect of temperature and light conditions of outside greenhouse, the temperature of outside greenhouse has the greatest effect on the soil temperature change , light of inside greenhouse, had a close interaction with light of outside greenhouse.
