【Objective】The method of intelligent crop integrated modeling was explored and a supported tools of modeling was developed. 【Method】By analyzing and extracting the crop （wheat, rice and cotton） growth models algorithm and simulation systems, the generic modeling flow, model framework, model interface and model template were extracted, and a growth meta-model for agronomic crops were developed. Based on the techniques of crop model resource library, model components, description script and engine, the structure and core parts of Intelligent and Integrated Crop Modeling Support System （IICMSS） with layer and component characteristics were designed.【Result】Based on .Net platform and SQL Server database,the prototype system was developed with C#, and a wheat growth simulation model and system was reconstructed using the IICMSS. Compared with the code-based wheat growth simulation system, the development approach of the model system reconstructed by the IICMSS has been improved, which facilitates crop model and system development, testing, maintenance and sharing.【Conclusion】The IICMSS realized flowchart process of crop modeling industrialization of modeling method, generalization of interface and transparent of models. In IICMSS, a crop model can be developed by scientists/modelers with no-code automatic approach through studying, customizing, designing, configuration, assembling, evaluation and extension.
