Abstract
Taking new maize cultivar Zhengde 306as test material,5planting densities with randomized plot design were adopted on study of effects of planting density on agricultural traits and yield of Zhengde 306.The results showed that the best planting density in Hexi area was 82500plants/hm2,the yield was 16308.15kg/hm2,the appropriate planting density were75000~82500plants/hm2,difference of yield was not significantly under these 2planting densities.Correlation of planting density and ear length,diameter of ear,rows per ear,grains per row,grains per ear,thousands weight were negative,correlation of planting density and ear length,rows per ear,grains per row,grains per ear were obviously negative,correlation of planting density and diameter of ear,thousands weight were not obviously negative.
