摘要
棉花生育进程以及株高、果枝果节数和干物质积累动态是反映棉花个体与群体生育状况的重要标志。在分析棉花生育进程以及产量要素形成和干物质积累等与产量目标和环境因子定量关系的基础上,建立了基于基因型差异和有效积温的棉花生育进程模型以及群体生育动态知识模型。利用不同生态点、不同品种和不同产量目标等资料对知识模型进行了测试和验证,表明知识模型具有较强的决策功能和适应性。
Growth phase, plant height, fruit branch number, fruit site number, dry matter accumulation are importantfeatures for description of individual and population characters in cotton. By analyzing the relationships of developmentprogress, yield factor formation, dry matter accumulation to target yield and environment, a knowledge model for developmentprogress and growth dynamics in cotton was developed driven by the genotypic difference and effective temperatureaccumulation. Case studies on the knowledge model with the experiment data sets of different eco-sites, varieties and targetyield indicated a good performance in decision-making and applicability.
