Abstract The result of the experiment indicated that spectrum conversion film had higher light transmittance charac- ter and increased temperature in tunnel remarkably,as compared with common film(CK);the spectrum conversion film, when temperature was low,could enhance the air temperature and 5 cm deep soil temperature in tunnel by 0.5～0.9℃and 0.7～1.3℃respectively,but when temperature was high,it could decreased those by 0.2～1.0℃and 0.2～0.6℃respectively.So spectrum conversion film remarkably increased yield and impr...
