Influence of various gauge lengths, root spacing and root numbers on root tensile properties of herbaceous plants

The mechanical properties of root system play an important role in soil reinforcement by plants. Root tensile properties are affected by many factors. It is necessary to explore the mechanical properties of root system and the influencing factors. In this study, tensile tests were conducted on roots...
