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...
