To fully utilize the advantages of 3S(GIS,RS,GPS) technologies,crop growth simulation model and crop management knowledge model,and to grope into the integration method and application mode of key technologies in precise farming adapted to Chinese circumstance,a model and 3S-based digital wheat farming system was developed based on plentitude combination of wheat growth simulation model,wheat management knowledge model and 3S technologies.Guided by the methodology of software development,the system was programmed with the languages of ASP.NET and C#.By inputting the parameters of varieties,climate,soil and production condition,the system realized the functions of wheat farming zone,cultivation strategy design,growth prediction,strategy evaluation, dynamic regulation,growth monitoring,precision management,productivity evaluation,management of disease,insect and weed,intelligent learning,system management and system help.The case study of the system with the datasets in some eco-sites of Jiangsu province indicated that the system can provide digital and scientific decision supports in wheat farming for farmers,agronomists and researchers.
