Abstract:Study on the effect of maize special synergistic agent on agronomic characters of maize in the density of 75 000 plants/hm2. The result indicated that there were obviously different on the different level synergistic agent to maize; intelligent use synergistic could decrease the plant height, ear height, lodging rate, empty stalk rate, lobe length, increase stem diameter and 1000 kernels weight, stabling ear length, ear diameter, lines per ear, kernel number per line, kernel rate, increase the maize yield. The suitable use consistency of maize Luoyu 5 is 150-200 mL/hm2.
