摘　　要：根据试验资料,系统分析了加工番茄叶面积指数变化规律,在综合考虑产量目标、品种以及生产措施等影响因子的基础上,以生理发育时间(PDT)为预报变量,以相对化叶面积指数(LAI)动态数学模型为基础,运用知识工程和系统建模方法,建立了系统化加工番茄适宜叶面积指数动态设计的知识模型。利用不同年份、不同播期、不同品种和不同密度的试验资料对模型进行了验证,结果表明模型具有较强的可靠性和适用性。On the basis of analyzing the development of leaf area in processing tomato, a dynamic knowledge model for LAI of processing tomato in relation to yield targets, planting densities, sowing date and cultivated varieties was developed through knowledge engineering and system modeling methods. The model was driven by physiological development time and by quantitative relationships of normalized leaf area index to relative development time and can be used for designing the suitable time-course dynamics of leaf area index. Case studies on the knowledge model with the experiment data of different year, different variety types and production condition indicated a good performance of the model in guidance and applicability.
