环境因子是制约蔬菜产量与品质的关键因素。为了精准指导温室番茄生产管理、探索环境因子变化对其影响，利用无线传感网络（ Wireless Sensor Network ， WSN ）采集了连栋温室番茄在不同生育期、高度、位置下环境因子数据。数据分析发现：不同发育期温湿度变化范围不同，光照强度减弱，光照时间减少，二氧化碳浓度变化延迟；白天，冠层的温度、光照强度比其他高度的大，湿度比其他高度的低，中间层与根部接近，夜间3个高度环境因子相近；不同位置温度由南向北、湿度由北向南呈高到低之势，光照强度和二氧化碳浓度最大差值分别为6562．5 lux及93．76×10－6。测试结果表明：WSN可为番茄连栋温室环境调控提供参考和决策支持。

The key factors that restrict the yield and quality of vegetables are the environmental factors.In order to ex-plore the change regulation of environmental factors in greenhouse, we used Wireless Sensor Network ( WSN) to get the data of environmental factors at different height and location in different time.The results of analysis show that the range of temperature and humility were different, light intensity reduced, illumination time shorter and changes in carbon diox-ide concentrations delayed.During the day, the canopy temperature, light intensity is higher than others, the humility is lower than other heights and the intermediate layer close to the root layer, while the three layers were close during the night.Temperature from south to north and humility from north to south were high to low, the maximum difference of light intensity and CO2 concentration are 6562.5lux , 93.76ppm,respectively.Test results show that the WSN can pro-vide reference and decision support for greenhouse environmental control.
