日光温室番茄植株体温变化及其温度场的影响

随着日光温室管理的精细化程度越来越高,温室中作物环境因子的调控应尽可能适应植物生长的需要。用红外测温仪和温室气象站测定了日光温室内番茄植株体温及其周围气温。结果表明,日光温室番茄植株上部与下部存在温差,且有明显的日变化,差异最大值在3℃左右。植株体温与周围气温存在明显的差异,最大差值2.7℃出现在中午时段。

Study on the Changing of Plant Temperature and the Influencing of the Temperature Field in Greenhouse

As the result of the increasingly sophisticated of greenhouse management,the control of environmental factors of the plant should reflect itself as far as possible.The plant temperature and the around temperature was measured using the infrared thermometer and automatic meteorology station.The results showed that there was temperature difference between the above and the below of the tomato plant,which had daily changes,and the biggest margin of temperature was about 3℃.The difference between the plant temperature and around temperature was clear,and the biggest margin of temperature was 2.7℃,which appeared at noon.
