Measurement of crop rooting system architecture and the calculation of root fractal dimensions plays an important role in precision crop rooting management. A technique for root visualization and analyzing was proposed to assess field state post-paddy wheat rooting system architecture. The proposed technique applied a root digitizer to measure wheat root system architecture, and changed the root system architecture into 3-D coordinates. The collected root topology data was then transferred to Pro/E platform for 3-D reconstruction. When the virtual root system was reconstructed, it was projected on three coordinate planes. The projected 2-D root architecture was then analyzed to derive fractal dimensions and fractal abundances. Results showed that the method could quantify the dynamics of the field-state wheat root system architecture. Both root fractal dimension and fractal abundance increased over time. Fractal dimension and fractal abundance in the top plane were always higher than that in the right plane. Starting from 98d after sowing, a rapid increase of fractal dimension and fractal abundance was observed in the front plane. Fractal dimension was, for all the three projections, strongly correlated to fractal abundance. Also, the fractal dimension and fractal abundance were both correlated to total root length.
