Based on the maize ecophysiological characteristics, the maize developping process-based cooperative models including growth model, developmental phase models, water balance model and nitrogen balance model etc. was built combined with the basic data such as variety characteristics, weather data, soil level and cultivation management with the technology support of system engineering method, crop simulation and computer. On the basis of cooperative models, this paper further constructed Maize Production Emulation System (MPES) with several additional functions such as determining variety characteristic parameters, deciding the planting design, simulating maize phenology stages and production features, warning of the nitrogen leaching in advance, simulating the water and nitrogen deficit degree and maize growth three-dimensional display. The system reproduces the maize production process in digital form. MPES was test through actual experiment, and the results verified its strong mechanism and prediction performance as well as its universal adaptation.
