Based on the simulation experiments of nitrogen transport, transformation,uptaking and nitrogen removed under the different condition of wastewater land treatmen in the greenhouse, growth of crop, growth and distribution of roots, uptaking pattern of water by roots, the relationship between competitive uptaking and water, nitrogen content in soil, etc.,was analyzed, and an united computing model of crop growth, distribution of roots, water and nitrogen uptaking by roots and transformation in soil-crop system was developed. According to simulating experiments, numerical modeling and analyzing of crop growth status,root growth condition and water, nitrogen movement, uptaking and transformation, and nitrogen removed process under different watering and nitrogen pollution conditions were made and the model was calibrated by observing data. It provided a primary computing method for selecting an efficient , productive watering and wastewater irrigating plan, namely Urban wastewater land treatment controlling plan.

 water balance sub model of crop growth model, CERES wheat model, which was established originally by American scientist J.T. Ritchie et al., was applied to simulate soil moisture of a fixed winter wheat plot at the Xifeng Agrometeorological Experimental Station, Gansu Province, located in semi arid zone. Corrections were made to estimate potential evapotranspiration, soil surface evaporation, crop transpiration, and root density and maximum rooting depth. Both the density and depth were represented as two functions of crop developmental stages respectively. The improvement achieved good results in soil moisture prediction and may provide a convenient and practical method for management of croped soil moisture in arid or semi arid zone.
