Abstract
The experiments for nitrogen nutrient management in maize in cold area were carried out with the methods of field plots. The results showed that maize plants and and nitrogen accumulation in vivo is similar to fertilizer. Fertilization rate had little impact on this experiment for yield. The best dressing time was the ten leaf-stage period. and 10 leaf-age 8 leaf-age 12 leaf-age 14 leaf-age, 10 leaf-age, 8 leaf-age and 12 leaf-age, 14 leaf-age were different significantly. It increased production by 7.3% than 12 leaf-age stage, than 14 leaf-age by 9.1%. With the growing period for corn, after tasselling period in the plant body nitrogen transfer from vegetative organs to reproductive organs, and the highest productionvalues were in treatment 150 kg·hm-2. 10 leaves top-dressing can significantly increase nitrogen accumula-tion of corn after tasselling period. With sample of the production rule, nitrogen application rate had on effect on nitrogen accumulation of corn. We also got the plant will receive the maximum yield when corn leaf nitrogen accumulation amounted to 1.55 g·plant-1 in tasselling period of cold in area.
