Abstract
入射於地表的日光，可分為三個波段，紫外光區(<400 nm)、可見光區(400-700 nm)和近紅外光區(700-3000 nm)；各波段所佔的能量分別為3%、44%和53%。其中僅有可見光區的能量可以被作物光合作用所利用，其於兩個波段的光能對光合作用毫無用處，但卻可以轉變成熱能，使得設施內的溫度升高。
Incident solar radiation on earth can be divided into three regions, ultra-violet (300-400 nm), visible (400-700 nm) and near-infrared (700-3000 nm); and the energy contained are 3%, 44%, and 53%, repectively. Although energy in the visible region can be used by phytosynthesis, radiant energy in the other two regions can only be converted into heat and then raise temperature in greenhouses.
