摘　　要：刚发芽的马蹄莲除自然光照外,于每日18:00～24:00补照0、2、4和6h的不同光质的光[蓝光:(475±5)nm、黄光:(585±5)nm、红光:(660±5)nm、复合波长的白光].38 d后,补照红、蓝、白光的植株光合速率,从高到低依序为0h>2 h>4h>6h,补照黄光的依序为0h>2h>6h>4h.生长情况以补照6h黄光和2h蓝光的效果最好,补照2h红光或4h白光的次之,补照6h白光和6h蓝光的最差.During the night （18：00-24：00）, Zantedeschia aethiopica were added light 0, 2, 4, 6 h with different qualities [blue： （475±5） nm, yellow： （585±5） nm, red： （660±5） nm, white： complex wave] everyday after natural light when it was just burgeon. After 38 d, photosynthetic rates of Z. aethiopica from high to low were 0 h〉2 h〉4 h〉6 h under blue, red and white light, and 0 h〉2 h〉6 h〉4 h under yellow light. The growths were best under yellow light for 6 h and blue light for 2 h. The effects of red light for 2 h and white light for 4 h were next, while effects of white light for 6 h and blue light for 6 h were worst.
