Modeling plant growth is important to further study on the plant development process, especially for digital agriculture field. Virtual plant model can help to observe the plant growth process and discover some recondite rules, which could be constructed based on large numbers of experimental data during the plant development. The growth model can be obtained after dealing with experimental data, while the changes including topological structure and organ morphology during the plant growth could be described using virtual technology. Then the virtual plant development model can be expressed with the information fusion and reconstruction method. The experimental results showed that the presented model was feasible and effective on simulating plant growth on computer, which also greatly demonstrated its valuable evidences in predicting the plant growth rules under different environmental conditions.
