棉花产量目标和产量结构的动态知识模型

A Dynamic Knowledge Model for Yield Target and Yield Components in Cotton

通过分析和提炼棉花皮棉产量及产量结构的最新研究资料,在综合考虑气候条件、土壤肥力和栽培技术水平等影响因子的基础上,建立了棉花产量目标和产量结构的动态知识模型。该模型可用于精确定量不同气候条件、不同土壤肥力和不同栽培技术条件下的产量目标以及基于品种特性的产量结构。利用不同生态点资料对知识模型进行了验证,结果表明模型具有较好的决策性和适用性。

By analyzing and extracting the newest researches on lint yield and yield components in cotton, a dynamic knowledge model for decisionmaking on yield target and yield components was developed by integrating the effects of climatic conditions, soil fertilities, management levels and variety types. Case studies on the knowledge model with the experiment data sets of different ecosites, soil fertilities, management levels and variety types indicated a good model performance in decisionmaking and applicability.
