不同光质补光对日光温室黄瓜产量与品质的影响

The effects of different light qualities(blue,red,UV-A,UV-B)on the quality of cucumber fruit growing in solar greenhouse were investigated and the contents of vitamin C,protein,and deoxidized sugar were measured.The results show that the vitamin C content of cucumber fruit under UV-B and red light is higher than that under UV-A and blue light;the contents of protein and deoxidized sugar in fruit under blue light are the highest among these under all the treatments.Under UV-A light the yield is higher than that under any other treatments.
