Abstract:

The effects of combined application of Nitrogen, Phosphorus, Potassium and Zinc fertilizer on the physiological of flag leaf on wheat were studied using Split-plot experimental design. The results showed that the activity of SOD, POD and GDH were increased by using Zinc fertilizer,and the increment was 35.7% of SOD, 10.3% of POD and 38.7% of GDH, and the most obvious effect was the N mixed which could improve the yield and quality. And also showed that there was little effect on SPS by using Zinc fertilize but Phosphorus and Potassium could improve the SPS activity obviously, the increment was 36.5%, then the sucrose of wheat were increased.
