To solve the problems of severe soil adhesion, high working resistance and high fuel consumption for imprinting wheel operates on loam soil area in south-China. A bionic surface for imprinting wheel which could reduce working resistance was designed inspired by the special non-smooth body surfaces of Red Swamp Crayfish（procambarus clarkii）. The geometrical surface of bionic convex with micro-spikes Crayfish was studied, and its excellent antiadhesion property was investigated by soil adhesion tester. The Discrete Element Method（DEM） was used to establish a theoretical model to study the interaction between soil and imprinting wheel. The results showed that the bionic micro-spiked convex surface could reduce soil-adhesion. The computer simulation and soil bin test have a good correlation, the forwarding resistance decreased with the increase of the length of micro-spikes. The resistance reduction was between 5%-10%.
