| Abstract： | Objective: In order to provide intelligent and digital decision support for tomato processing management, a dynamic knowledge model for design of tomato processing yield target and yield components was developed. Methods: By analyzing and extracting the relationship among yield, yield components, environment, and production technology level, the quantitative mathematical method based on solution of a question was set up. In the model, the effects of climatic conditions, average yield level of last three years, soil fertilities, fertilization and water management levels, production technology level and variety types were considered synthetically. Results: Case studies on the model of target yield design with the data sets of four eco-sites under normal climatic year, soil fertilities, management levels and variety types indicated a good performance of model system in decision-making and applicability. Conclusion: The model can be used to calculate the tomato processing yield target and yield components accurately under different climatic conditions, soil fertilities and cultivation technique levels. |
