Effect of Foliage Spraying SOD Liquid Fertilizer on Wheat Growth and Yield Components

Different concentration of SOD liquid fertilizer(CK,100,300,500 times dilution) was applied on wheat in jointing stage by foliage spraying in order to study its effects on wheat growth and yield components.The results showed that spraying SOD liquid fertilizer could promote the photosynthesis and dry matter accumulation which resulted in yield increasing.Different concentration of SOD liquid fertilizer had different effect on yield,as the yield was increased by 13.13%,19.55% and 6.28% compared with CK in 100,300,500 times dilution of SOD liquid fertilizer treatment respectively.Foliage spraying of liquid fertilizer SOD was a simple stimulation with high input-output ratio.
