| Abstract: | The effects of planting density and nitrogen supply level on the biomass and interrelated characters of Yuqing 1 were studied.The results indicated that planting density and nitrogen supply level were the key factors influencing the biological yield.The optimal nitrogen supply level was 225kg/hm2.The best maize planting density was 82500 plants/hm2.Nitrogen supply and planting density both iad influence on the interrelated characters. |
