Dynamic Change of Water Storage under Anti-Drought Measures on Red Soil Slope Farmland
Seasonal drought and soil erosion happened alternately on red soil slope farmland, which severely restricted its full productivity. This project took down-slope tillage as a control and different soil reservoir construction measures’ slopes as subjects, studying their soil reservoir storage function and dynamic change of water storage, in order to study the mechanism of water-retaining and regulating capability in different soil reservoir construction measures’ slopes. The results show that the max. and min. volume of water storage in pits I, pits II, pin hole Iand pin hole IIare 19.67%, 32.14%, 17.61%, 17.17% and 14.06%, 16.46%, 10.20%, 11.82% higher than the control respectively. Monthly changes of water storage in different soil layers of the control were more than those in construction measures’ slopes farmland, which were minimal in pit II, Water storage increased first and then decressed with the increase of soil depth, but the changes of water storage at 0-40 cm layer were more greater than that at 80-100 cm layer in all the slope farmlands, which provided stronger water regulating capability.
