Abstract:: The pressure of root system on soil is a synthetically mechanical index of reflecting the root-soil composite system. An introduction to a new apparatus, which can measure the pressure of root system on soil, is designed and manufactured. The experimental data measured using the new apparatus with the air-medium and liquid-medium are obtained. The new apparatus with the liquid-medium can also meet the demands of an experiment for measuring the pressure of root system on soil during the plant growing period. It is shown by the experimental data measured using this new apparatus is suitable to measure the pressure of root system on soil with high accuracy.
