With the aim to study the mechanical properties of wheat stalks fracture, a kind of control system for the mechanics testing of wheat stalks was developed .The test equipment mainly included control section, executive body, information collection and display module, among which the quite accurate data acquisition system was very simple to operate. The experiment results show that the system is stable and reliable ,with the deviation of collection data lower than 0.1%, which can fulfill the system requirements and test the wheat stalks feature in mechanics and physics. It provides an effective and reliable method and tool for material mechanics.
