Both planting density and amount of nitrogen fertilization have significant effect on chief group properties of two-ear rate, blank-stem rate, lodging percentage and ear’s height. With increasing planting density, two-ear rate yields a significant decrease while blank-stem rate, lodging percentage and ear’s height go up to perspective degrees. With increasing amount of nitrogen fertilization, two-ear rate decreases after initial increase while blank-stem rate, lodging percentage and ear’s height go up to perspective degrees. There’s a significant interaction effect on chief group properties between planting density and amount of nitrogen fertilization. The further study indicates that planting density and two- ear rate have a significant negative correlation; amount of nitrogen fertilization and ear’s height have no significant correlation; planting density, amount of nitrogen fertilization and chief group properties of waxy corn have a significant positive correlation.
