| Abstract: | The effects of density and nitrogen fertilizer on the grain yield and population structure in maize hybrid Zhenghong No.2 were studied through the field experiment of split plots design of two factors with five levels.The optimized models for both planting density and nitrogen fertilizer quantity were established.The results indicated that the techniques of high yield cultivation of Zhenghong No.2 for yield above 7 500 kg/ha were as follows: the planting densities of 58 542.2-75 474.3 plants/ha,and the nitrogen fertilizer amount of 188.50-336.50 kg/ha. |
