- Abstract:
-
To study the soil and water conservation function of cover plants on the forest floor, the water absorption of stem and leaves, the soil anti-erodibility and the soil permeability were measured with 12 cover plants using the indoor leaf immersion method, the hydrostatic collapse method, and the bicyclic knife method, respectively. The results showed that Calamagrostis brachytricha and Phalaris arundinacea var.picta had the highest water absorption over 40% of the stem and leaves weight; Phalaris arundinacea var.Picta, Carex lanceolata and Carex leucochlora best increased the soil anti-erodibility; the cover plants decreased the soil bulk density and generally increased the soil permeability, and the permeability of soils planted with Phalaris arundinacea var.picta, Pennisetum alopecuroides, C.brachytricha, C.leucochlora, C.lanceolata and Cosmos sulphureus extremely significantly differed from the control. Therefore, C.leucochlora, C.Lanceolata, P. arundinacea var.picta and C.brachytricha have the higher integrated soil and water conservation function and fit to be planted under the forest.
