A Study on Transformation and Transportation of Nitrogen in the Root Zone of Winter Wheat in the Fields

Wu Xiaofeng;Xie Senchuan(Tsinghua University Beijing 100084)  
On the basis of long-term field experiment on winter wheat, the mathematical model of water and different kinds of nitrogen in the soil-plant system is set up. This model involves the mineralization of organic N, nitrification and volatilization of ammonium N,denitrification of nitrate nitrogen, absorption of soil and uptake of plant and so on. The distribution and changes of water, ammonium N and nitrate nitrogen in the field during winter wheat growing season are simulated with solute diffusion-convection equation. Comparation of experiment data with calculation results indicates that under the condition of different irrigation quota, the application amount by 60 mm of water each time can basically satisfy the needs for plant growth and cause little loss by deep percolation. However, increase of irrigation quota, can result in more loss by deep percolation while the increase of plant uptake is rather limited. Because of the downward movement of dissolving nitrogen into the deep layer along with soil water, nitrogen uptake by plant decreases whereas the loss of nitrate nitrogen by deep percolation increases remarkably.
