Augmented Reality is a new technology which can combine the real world information with the virtual world information seamless. In order to increase the sense of immersion and interactivity, thereby improving agricultural information service capabilities and expanding the exchange of seed industry exhibition and promotion capabilities, this paper provides a kind of interactive method to simulate the plant growth. Based on the target tracking localization algorithm of ARToolkit, through the relative distance positioning two rectangular markers, corresponding to different plant growth development period, the method can interact to realize the control of virtual objects, such as translation, rotation and zoom. The experimental results show that the method can simulate the true process of the wheat plant growth, that can simulate different kinds of virtual wheats. The method has a good compatibility, low requirement on the hardware, stable capability, better expansibility and transferability.
