我們可以看得到，在很多溫室大棚中裝有二氧化碳記錄儀
，很明顯這是用來監測棚內CO2濃度用的，至於為什麼要對其進行檢測，我們卻不知道。

    當dang儀yi器qi檢jian測ce到dao二er氧yang化hua碳tan濃nong度du低di於yu限xian定ding值zhi時shi，就jiu需xu要yao在zai大da棚peng裏li充chong二er氧yang化hua碳tan，目mu的de就jiu是shi為wei了le提ti高gao大da棚peng裏li的de溫wen度du，因yin為wei二er氧yang化hua碳tan是shi溫wen室shi氣qi體ti可ke以yi更geng好hao的de吸xi收shou來lai自zi太tai陽yang和he地di麵mian的de長chang波bo輻fu射she。提ti高gao空kong氣qi的de溫wen度du。另ling外wai
