Connection Force Determination between Crop Roots and Soil

Abstract:

A method of determining the connection force between crop roots and soil was developed. A TG-1 tensile testing device was designed which consisted of an activities tripod platform, a screw mechanism, a special clamp and sensor-signal processing system. The force transferred to the screw mechanism with the help of a hand wheel was only 1/97 of the maximum connection force between crop roots and soil. The clamp used self-locking structure, and it could clamp most of the crop stalks with different diameters. Take the maximum connection force as the measurand for the connection force between crop roots and soil. Using the TG-1 tensile testing device, experiments were carried out on oilseed rape. The results showed connection force between oilseed rape roots and soil ranged from 36N to 237N. The proportion of the force between 100 and 150N was the most, taking up 45.5%.
