METHOD FOR MEASURING GROWTH OF ROOT OF PLANT

摘要

PURPOSE: To measure degree of growth of root of plant utilizing an elastic wave called AE(Acoustic Emission) wave. ;CONSTITUTION: An acoustic plate is arranged in the vicinity of the root of a plant in soil. Thereby, fine elastic wave generated by friction of grains constituting soil when soil is moved as the root is grown is measured through the acoustic plate.;COPYRIGHT: (C)1994,JPO&Japio
