摘要
为指导日光温室同时考虑温度和辐射两个因素进行环境管理,依据气候空间理论,应用气候空间图的方法分析了番茄吸收来自环境的辐射与温度的关系。在晴天环境下,对日光温室内番茄群体的气候空间进行了研究,得到了其气候空间图。结果表明日光温室番茄气候空间随气温变化分3个区间段,气温小于16.7℃时和大于28.3℃时,吸收辐射与黑体辐射偏差较大,数据波动也较大;并且低于适宜温度时比高于适宜温度时偏离更大。而在接近番茄生长发育的适宜温度的16.7～28.3℃环境下,番茄吸收辐射更接近理想的黑体辐射;番茄的气候空间变化趋势与D.M.Gates研究得到的北美红雀气候空间辐射极限图相类似,不同的是,番茄群体吸收的太阳辐射会低于理想的黑体所能吸收的辐射。
The relationship between radiation absorption and temperature was analysed with climate space diagram based on climate space theory.The results show the climate space of the tomato in the solar greenhouse can be divided into three sections.When the temperature is below 16.7℃and above 28.3℃,the radiation absorption has a great difference compared with that of the black body,and the warp is bigger when the temperature is below16.7℃than above 28.3℃,and the data fluctuates greatly.When the temperature is 16.7～28.3℃,which is close to the most suitable temperature,the radiation absorption of the tomato is closer to ideal black body radiation.The climate space diagram of the tomato in the solar greenhouse is quite similar to that of the cardinal studied by Gates D.M,whereas sun radiation the tomato absorbs is lower than that of the black body.
