摘要：
In column experiments the effect of earthworm burrows (Allolobophora caliginosa, Allolobophora rosea) on soil hydraulic properties was measured. Saturated hydraulic conductivity as well as percolation rates were increased in columns with burrows compared with the control. In columns with A. caliginosa burrows saturated hydraulic conductivity was correlated with burrow length.
