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.

Based on the simulation experiments of nitrogen transport, transformation, uptaking by roots under the condition of wastewater land treatment of three kinds of planting density of wheat in the greenhouse (groups A, B, C With 0.0208, 0.1042 and 0.1415 pant/cm2), growth of crop, growth and distribution of roots, uptaking pattern of nitrogen by roots, and process of nitrogen removal in the soil etc., have been analyzed. The result showed that nitrogen uptaking quantity of group A was highest (49.90 mg/plant), in group B, under planting density, decreased of nitrogen accumulating in the soil equilibrated to the accumulating quantity of N2 from irrigated water, in group C, the applied amount of nitrogen was 2 fold of group B and 2.6 fold of group A, but the rate of nitrogen residue in soil was only 7.06% of nitrogen applied.

通过温室条件下,冬小麦3种不同种植密度下(A、B、C3组分别为0.0208、0.1042、0.1415株/cm~2),氮污染物运移转化吸收模拟试验,分析不同污水土地处理强度下植物生长、根系生长与分布、根系对氮污染物吸收规律以及根系竞争吸收与土壤中氮去除过程,探求最佳的污水土地处理条件和强度。试验结果是,A组单株吸氮量最大达49.90mg/株;B组种植密度下,土壤中氮累计减少量与随灌水累计加入量相等;C组的氮施入量是B组的2倍、A组的2.6倍,但土壤中氮的残留率仅是施入量的7.06%。
