Physical model experiments are increasingly applied in the study of water infiltration law loess with roots. In past, due to differences objects and limitations measuring techniques, roots is rarely evaluated by using appropriate indoor physical experimental data. order investigate roots, we designed a new soil column device that can automatically collect data images. By comparing experiment loess, analyzed variables root contents (the ratio mass dry mass) types. Roots diameters 0–2 mm, 2–5 5–10 mm defined as type I, II, III, respectively. It was found rate, water-holding capacity, saturated permeability coefficient increase content. containing different types, types were improve rate infiltration, soil. The ranked descending terms their impact: II had highest improvement, followed then I. phenomenon circumferential flow existed when infiltrated Root content would affect radius flow, path, cross-section. When calculating ignoring effect lead higher result.
