Rape adhesion property test system was constructed to test the adhesion property of rape mixture to bionic screen matrix, which was measured by adhesion rate μand adhesion reduction rateτwhich were correlative with residual adhesion area. Super-green feature extraction method of image technology was used to calculate the residual adhesion area. The results showed that the adhesion reduction ratesτof rape mixture to bionic screen matrix were more than 30% and even reached to 90%， which means an obvious adhesion reduction function of the bionic screen matrix. The results also showed that bionic convex surface could lower adhesion better than bionic concave surface with rape mixture. The adhesion degree of rape mixture on common screen was depend on the components of rape mixture while the adhesion degree of bionic nonsmooth screen was stable, which could adapt to different environments in the field and keep the lower adhesion function.
