摘　　要：很多植物都采用扦插育苗,为实现扦插植物的工厂化繁殖,研究其地下组织的生长规律及可视化模拟模型是研发扦插育苗机械化装备的基础之一。为此,基于几何建模的方法,结合扦插植物的繁殖特点,对扦插植物地下组织的构型进行建模;采用VC++及Direct3D图形接口,开发扦插植物地下组织的三维可视化动态仿真程序,并以扦插蔷薇的地下组织为样本进行模拟。结果表明:模拟仿真图形与实际扦插蔷薇的地下组织形态特征相似度较高,模拟数值与实测结果的相对误差小于10%。该研究为植物构型建模仿真提供了一个新的方向。Many plants are propagated by cottage to achieve industrialized seedling aim. The aim of this paper is to pro-vide foundation research for developing cottage seedling mechanical equipment through studying on the growth regularity and visualization simulation model of the underground organ. So, based on method of geometry modeling, according to propagating feature of cutting plant’s underground organs, an architecture model is designed, and a three-dimensional visual dynamic simulation program is developed based on VC＋＋and Direct3D graphical interface, and then the sample of Rosa is simulation object. By contrasting experiment and simulation data, results are shown： the morphological features are resemble between simulation images and experiment photograph;the relative error of simulation and experiment value is less than 10%. The study can provide a new aspect for the research on simulating the plant architecture.
