Abstract:
Taking Cynodon dactylon roots as the research objects，using a universal testing machine for single stretch to study the diameter relationship with the maximum tensile force and the maximum tensile strength.The results showed that the tensile force-displacement of Cynodon dactylon roots showed the type of linear,convex and continuous wave.The tensile force and the tensile strength relationship with the diameter could be fitting used by power function，quadratic polynomial and logistic model respectively，the correlation coefficient were higher than 0.9 and 0.7.The root of tensile force and the tensile strength increased and decreased respectively with the root diameter enlarging，through the fitting，the roots tensile force showed positive function correlated relation with the root diameter，the tensile strength showed negative function relation with the root diameter.
