| 摘要: |
| 为研究不同光截获对番茄植株形态结构的影响，基于结构-功能互反馈建模原理建立了番茄结构-功能模型。采用基于番茄拓扑结构的多目标估算方法，利用实验观测数据对模型进行多目标校准和验证。对局部遮阴和无遮阴栽培条件下番茄植株的生长过程进行动态模拟，并对不同生长阶段番茄植株的形态结构、器官周期累积生物量以及器官三维形态输出进行比较，结果表明：无遮阴栽培条件下，番茄植株茎杆节间短粗，叶片和果实较大。而局部遮阴栽培条件下番茄植株茎杆细长，叶片稀薄，果实较小。不同光截获下模型的输出结果与观测数据拟合较好，验证了模型的有效性。 |

| Abstract: |
| Tomato structural-functional model was set up to investigate the effect of different light environment on tomato morphology structure.To calibrate the model,multi-targets estimating method,which was based on the description of plant topological structure,was adopted to fit the field data.Two cases,i.e.no-shading and local-shaded plants were simulated by the model,and the comparative results were presented in view of the following aspects: morphology at different growth stages,cumulated biomass into organs and 3D visual output.The results indicated that no-shading plants have shorter and stronger stem internodes, bigger leaf and fruit compared with local-shaded ones.By model,the characteristics of morphology structure under different light interception were well simulated and fitted the field data very well,which verified the model was accurate. |
