| 摘 要： | 以温室黄瓜生长为例,对实验观测数据进行预处理并采用关联分析法获取植株-环境互作信息,依据作物发育动态理论模型建立了植株-环境的信息响应模型和信息反馈模型,再从植株生长的系统变化过程对相关模型进行耦合。运用规则化处理方法与面向对象技术建立植株拓扑演变模型与器官形态发生模型,并构建虚拟植物动态模型。实验表明,模型拟合度均达到95%以上,能较好地虚拟外部环境作用下的植物生长发育,为动态掌握和预测适宜植物生长的温室环境条件提供依据。

| Abstract: | It is important to construct virtual plant model based on the interaction between plant and environment for greenhouse environment control. Taking the greenhouse cucumber growth as an example, it would obtain plant environment interaction information with data pre-processing and association analysis method. According to the crop development theory model, the information response model as well as information feedback model could be established. Moreover, the models could be coupled with the plant development process. The plant topological model and organ morphological model would be founded using regularization method and object-oriented technology, and the virtual plant model could be constructed. The experimental verification results indicated that the goodness of fit of models could be up to 95%, and improved that the presented method was effective in simulating the plant development under the interaction of environment, which also provided valuable evidences for dynamical control and prediction of greenhouse environment conditions fitting to plant growth. |
