The Impact of Field Ridge Spacing on the Spatial Distribution Characteristics of Soil Physical Properties in the Northeast Black Soil Region
This study aims to clarify the spatial distribution characteristics of ridge plant belts on soil water-holding capacity and soil structure in sloping farmland, providing a scientific basis for optimizing ridge plant belt configurations and soil and water conservation measures in Northeast China's black soil region. Sloping farmland with ridge plant belts was selected as the research object (Ridge 1:ridge spacing of 12.5 m; Ridge 2:ridge spacing of 19.5 m), and sloping farmland was selected as the control. The uniform spatial point sampling method was obtained using basic physical property indicators in the surface layer (0-15 cm), and to quantify the differences in the spatial distribution characteristics of soil water-holding capacity and soil structure in sloping farmland with different spacing of ridge plant belts. The result showed that, the sloping farmland with ridge construction showed a significant increase in total porosity, capillary porosity, saturated water-holding capacity, field capacity, and capillary water-holding capacity, with a relatively uniform distribution across the slope. In addition, compared to the Ridge 2, the soil of Ridge 1 showed an increase of 0.96-1.11 times in total porosity, 1.21-1.31 times in capillary porosity, 1.03-1.25 times in saturated water-holding capacity, 1.22-1.78 times in field capacity, and 1.33-1.52 times in capillary water-holding capacity, respectively. The soil mechanical stable aggregate mass fraction, MWD (mean weight diameter), water-stable aggregate mass fraction, and GMD (geometric mean diameter) in the sloping farmland with ridge showed significant improvements across all fields. Compared to the controls, the sloping farmland with ridge increased by 1.01-1.15 times, 0.94-1.61 times, 1-1.17 times, and 1.05-1.55 times, respectively. This indicated that the sloping farmland with ridge effectively improved soil structure compared to the control. Moreover, compared to the sloping farmland with Ridge 2, the soil mechanical stable aggregate mass fraction, MWD, water-stable aggregate mass fraction, and GMD in the sloping farmland with Ridge 1 increased by 1.08-1.14 times, 0.95-1.28 times, 1.07-1.15 times, and 1.14-1.40 times, respectively. Constructing ridges can improve water-holding capacity and soil structure characteristics, with a more significant improvement effect observed in relatively small distances smaller distances between ridges.
