Study on Close Planting and Nutrient Improvement of Maize

The result of field experiment which 4 leaf straight-up type maize hybrids,3 planting model(50 cm row distance,6-angle shape,67 cm row distance),3 density(60 000 plants/ha,75 000 plants/ha,90 000 plants/ha) indicated that maize single plant round area with maize mass yield is up to 0.01 level of difference significant high positive interrelation,the optimum combination of Row×Density is that 50 cm row distance,90 000 plants/ha;not only is the maize yield highest but also be good for the cultivating of maize.
