摘要： Fertilizer application is an important part in super rice production. In order to investigate the effect of fertilizer amounts on the antioxidant performance of the super rice, three super hybrid rice cultivars, YLiangyou-1173, YLiangyou-911 and Chaoyou-1000, were used in the experiment. The fertilizer amounts were set as: (F1)1050 kg N ha(-1); (F2) 1200 kg N ha(-1); (F3) 1350 kg N ha(-1); (F4) 1500 kg N ha(-1); (F5) 1650 kg N ha(-1). The results showed that the activities of antioxidant enzymes were decreased when excessive fertilizers such as F4 and F5 were applied. Compared with F1, F4 and F5 significantly reduced the activity of superoxide (SOD, EC 1.15.1.1), guaiacol type peroxidase (POD EC1.11.1.7) and catalase (CAT, EC1.11.1.6). Furthermore, there was no remarkable significant difference related to the yield among F2, F3, F4 and F5.
