Study on Cultivation Pattern of Maize-Fengnuo476 for High Yield

The experiment was conducted to study the effects of planting density,base fertilizer and topdressing fertilizer by using the quadratic general rotary unitized design.The factors which affect the yield were: first,planting density,second,topdressing fertilizer,while base fertilizer had the least effect.The interaction between planting density and base fertilizer,which were positive interaction,was significant in the three factors.The optimum combination was that planting density per 667m2 was 4800,base fertilizer and topdressing fertilizer per 667m2 were 48.5kg.The simulated yield was 1296.34kg/667m2.
