| The surface fertigation solute transport model is developed with zero-inertia model as irrigation flow model and one dimension ADE equation as surface solute transport equation, and solving them separately with the methods of Preissman format finite difference and characteristic curve.It provides an effective model tool to optimize designation of technical parameters combination for fertigation.The research results show that there is good agreement between the measured data and the predicted result by the model, so the suggested model could offer an important tool for optimization of technique factors combination for fertigation;in the fertigation experiment, the research results with both the solutes of ammonia nitrogen and Br-are similar, so the research results in both conditions can be referred to by each other. |
