Abstract
By field experiments with Uniform Design,the effects of planting density and nitrogen rate on three varieties( Yunrui 8,Yunrui 6and Yunrui 88) grain yield under different ecological conditions were studied in Yunnan Province. The results showed that the grain yield were different among the five experiment locations,when increasing of planting density,it did not affected the plant height,ear height and ear factor,with the planting density increased,stem diameter,leaf width,ear length,number of grains per row and 1000-grain weight decreased significantly,but the grain yield of the third varieties increased. High planting density had a negative impact on ear traits,but the grain yield increased by high-density compensate for the adverse effects. Control space and time of fertilizer application can reach the highest yield under less Nitrogen fertilizer. Yunrui 88 had the characteristics of wide range of adaptability and the density-tolerance,high-yielding potential,which was favorable in planting on large areas.
