- Abstract:
-
In order to explore the effect of herbaceous roots on anti-erodibility, three treatments (i. e. sole Trifolium repens L., sole Loliu perenne L. and mixed sowing of Trifolium repens L. and Loliu perenne L.) were employed. The root characteristics of the three planting types were measured, of which effects on soil erodibility were compared. Soil detachment capacity by concentrated flow was measured in a hydraulic flume with the fixed bed under five different flow shear stresses to determine soil erodibility. The results showed that: (1) the root length density (RLD), root area ratio (RAR) and root weight density (RMD) of Trifolium repens, perennial ryegrass and mixed sowing of grass first increased from spring to autumn, then decreased and finally stabilized; (2) the soil erodibility increased in the order: Trifolium repens
R2>0.70); (3) soil erodibility was significantly and positively correlated with 0~1.0 mm root diameter (p<0.01), and positively correlated with 1.0~2.0 mm, 0~2.0 mm root diameter (p<0.05).
