Abstract [Background] The new polyurethane material (W-OH) has been widely used in soil and water conservation in our country, but its related theories lag behind its practice. Therefore, the study chose the two typical erosion soils red clay of slope cultivated land and arenosol of collapsing gully as objects and analyzed their infiltration and water-sand characteristics under the spraying of different W-OH concentrations. [Methods] Studying how much the new W-OH material influences the typical southern erosion soil in the infiltration, runoff and sediment was conducted. by indoor infiltration experiments and outdoor artificial simulated rainfall tests. [Results] 1) The nutrient of red clay soil and collapsing gully soil was infertile. The content of sand, powder and clay soil in red clay was almost equal. The content of sand in collapsing gully soil was more than 2/3, and the content of clay was only about 5.4%. 2) The spraying W-OH obviously reduced the infiltration rate of the two kinds of soils. With the increasing concentration (0-7%), the average infiltration rate of the red clay soil decreased from 6.98 to 1.42 mm/min and the collapsing gully soil decreased from 5.26 to 2.01 mm/min. The spraying of W-OH had a better effect on reducing the infiltration rate of red clay soil than that of collapsing gully soil. 3) The red clay soil sprayed with 5% W-OH showed an increase of 190% in the average flow rate and a decrease of 73.9% in the rate of sediment yield. The collapsing gully soil sprayed with W-OH showed similarly an increase of 37.3% in the average flow rate and a decrease of 62.1% in the rate of sediment yield. The spraying of W-OH increased runoff and decreased soil loss obviously. 4) The spraying of W-OH presented an inconspicuous impact on the average moisture content of the two kinds of soils before, after rainfall and 24 h later. [Conculsions] This study may provide a theory basis for W-OH's further application to the control of water loss and soil erosion in arable land of southern slope and collapsing gully.
