Abstract: In this research, the author studied the effect of photosynthesis biological synergist on growth, yield and quality of summer maize, and explored the best spraying concentration of photosynthesis synergist. Experiments were carried out for two consecutive years with the material of‘Zhengdan958’, and effects of different concentration of photosynthesis synergist on growth, yield and quality of summer maize were compared. The results showed that the yield increase effect of spraying 675 g/hm2 of plant photosynthesis biological synergist was the highest. Compared with CK, spraying plant photosynthesis biological synergist could increase the kernel number per ear and 1000-kernel weight, and increase the SPAD in leaf, prolong photosynthetic capacity and improve grain quality. The best spraying concentration of photosynthesis synergist was 675 g/hm2.
