This paper mainly focused on the growth law, model construction and visualization of a soybean root. A pot experiment was conducted in the laboratory to collect root system data and measure soybean root's length, diameter and number by excavating in different periods. On the basis of an in-depth analysis of root structure geometry, the author analyzed the collected experimental data with logistic equations, and got the growth of soybean root equation, according to its morphological structure characteristic of self-similarity, and discussed the virtual modeling method on the soybean root based on L-system and in visual C++using OpenGL technology to achieve a soybean root system topology model and visualization simulation.
