Plant stem strength is a major factor in crop lodging resistance. Lodging of maize, sorghum, tobacco, etc., has long caused great difficulties in crop mechanical harvesting. At the mechanized level, a lot of food is wasted. In addition, crop lodging leads to inadequate light, which greatly limits its production. It is of great significance for crop cultivation and breeding to measure stems in vivo at each stage of crop growth, and then make statistical processing of population measurement data according to the correlation between bending resistance and lodging resistance of stem fiber layer. The instrument adopts tension pressure sensor, by applying pressure, can be measured by needling, crushing, breaking the instantaneous generation of the most powerful, that is, the strength of the stem.
