摘　　要：通过自研发的叶温与环境因子采集系统对叶温、室内光照强度、温湿度、CO2浓度、地温、土壤湿度长期实时监测,研究了温室中环境因子变化对番茄叶温的影响。结果表明,棉被揭开后,叶温与室内光照强度变化有相似的趋势,但二者变化存在一定差异;全天时间段叶温变化与室温变化一致;叶温变化与CO2浓度变化呈相反趋势;叶温与地温变化趋势相近,但地温变化滞后于叶温2~3 h;土壤湿度全天时间段变化微弱,室内湿度变化较大。室温直接影响着叶温的变化,室内光照强度、CO2浓度、土壤温度通过影响室温间接影响着叶温的变化。室温是影响番茄叶温的主要环境因子,通过指导室温变化提高作物新陈代谢,进而提高作物产量与品质。Through the self-developed collection system of leaf temperature and environmental factors,the long-term real-time monitoring of leaf temperature,indoor light intensity,temperature and humidity,CO2 concentration,ground temperature and soil moisture was conducted to study the influence of environmental factors on tomato leaf temperature in greenhouse.The results showed that the changes of leaf temperature and indoor light intensity had a similar trend after the cotton quilt was opened,but there were some differences between them.The change of leaf temperature was consistent with that of room temperature during all day.The change of leaf temperature was opposite to that of CO2 concentration.The change trend of leaf temperature was similar to that of ground temperature,but the change of soil temperature lagged behind that of leaf temperature by 2-3 h.The change of soil moisture was weak during the whole day,and the indoor humidity changed greatly.Room temperature directly affected the change of leaf temperature.Indoor light intensity,CO2 concentration and soil temperature indirectly affect the change of leaf temperature through the influence of room temperature.Room temperature is the main environmental factor affecting tomato leaf temperature,which can improve crop metabolism,yield and quality by guiding the change of room temperature.
