The features of plant growth could be extracted from the experimental result s, and the morphological model of plant could be constructed with the parameter of accumulative growing degree day. Additionally, the digital growth model of pl ant could be performed using information reconstruction method such as informati on normalization and mapping process. The experiment results showed that the pro posed method was effective in dynamically simulating the plant growth under the interaction of environment. It could provide valuable evidences for real time ob taining and determining the proper conditions for plant development. 
