Abstract The objective of this study was to measure the stemflow amount by Glycine max and determine the effect of leaf area and rainfall intensity on stemflow of Glycine max at different growing stages.The experiment was conducted in the laboratory using a rainfall simulator.The results showed that the mean ratio between stemflow and total rainfall is 16.77%,and the highest ratio reached 32.15%.The amount of stemflow from Glycine max increased as Glycine max leaf area and rainfall intensity increased.The ratio between stemflow and total rainfall increased as leaf area increased and decreased as rainfall intensity increased.Two simple equations were built to describe those two relationships.This results provides theoretical direction for study the water redistribution in Glycine max canopy.
