摘要

A knowledge model with temporal and spatial characteristics for the quantitative design of a cultural pattern in wheat production,using systems analysis and dynamic modeling techniques,was developed for wheat management,as a decision-making tool in digital farming.The fundamental relationships and algorithms of wheat growth indices and management criteria to cultivars,ecological environments,and production levels were derived from the existing literature and research data to establish a knowledge model system for quantitative wheat management using Visual C++.The system designed a cultural management plan for general management guidelines and crop regulation indices for timecourse control criteria during the wheat-growing period.The cultural management plan module included submodels to determine target grain yield and quality,cultivar choice,sowing date,population density,sowing rate,fertilization strategy,and Water management,whereas the crop regulation indices module included submodels for suitable development stages,dynamic growth indices,source-sink indices,and nutrient indices.Evaluation of the knowledge model by design studies on the basis of data sets of different eco-sites,cultivars,and soil types indicated a favorable performance of the model system in recommending growth indices and management criteria under diverse conditions.Practical application of the knowledge model system in comparative field experiments produced yield gains of 2.4%to 16.5%.Thus,the presented knowledge model system overcame some of the difficulties of the traditional wheat management patterns and expert systems,and laid a foundation for facilitating the digitization of wheat management.
