Effects of Interactions of Different Planting Density and Chemical Control Agents on Agronomic Characters and Yield of Jundan 28
[Objective] The aim was to discuss the effects of interactions of different planting density and chemical control agents on agronomic characters and yield of Jundan 28.[Method] The interaction of four planting density and five chemical control agents were analyzed,and taking the commonly planting as control.[Result] Under the same planting density,the effects of different chemical control on yield was different; the maize plant height and ear height of all chemical control agents treatments were all lower than those of control,while stem diameter were higher than those of control; with the increase of planting density,the ear length,rows per ear,grains per row,and 1 000-grain weight all showed decreasing tendency,while the volume weight had a little change; the yield of Jundan 28 was the highest under the interactions of planting density 75 000 plants per ha and chemical control agents.[Conclusion] The study provides a reference for high yield and good quality cultivation of Jundan 28.
