In order to further study the effect of SOD liquid fertilizer on the growth and yield components of wheat, different concentrations of SOD liquid fertilizer were used to conduct the foliar spray test at the jointing stage of wheat. The diluted concentrations were 100, 300, and 500 times respectively. Equal amount of fresh water as a control. The results showed that 1 spraying of SOD liquid fertilizer could promote photosynthesis and dry matter accumulation of wheat and increase the yield. 2 The spraying of 3 different concentrations of SOD liquid fertilizer at the jointing stage had different fertilizer effects, and the yield of treatment 2 was 19.55% higher than the control. Treatment 1 increased 13.13% over the control, and treatment 3 increased 6.28% over the control. It shows that foliar spraying of SOD liquid fertilizer is a simple and easy-to-follow measure with a relatively high rate of return. It is a practical technology in the high-yield and high-efficiency cultivation of wheat, and has a higher value of promotion and application.
