- Abstract:
- The nanometer materials applied in the nutrient loss control could improve the utilization rate of soil water and improve soil physical structure. Based on the artificial simulated rainfall experiment in Shenmu County, Shaanxi Province, we analyzed the different contents of nano carbon (0.0%, 0.1%, 0.5%, 0.7%, 1.0% in mass) on the nutrient affect the migration process on loess slope. The results showed that planting the same crop community adding different concentration of nano carbon has not the obvious effects on nutrient losses. Five kinds of underlying surface conditions, the nitrogen, phosphorus and potassium loss amounts in runoff on the slope all present a decreasing trend with the increase of nano carbon contents, when the nano carbon contents are 0.5% and 0.7%, the effect of reducing nutrient loss amount in runoff is more significant. Under the conditions of different nano carbon contents, the nitrogen, phosphorus and potassium loss amounts decrease in the order:bare land > corn > Korshinsk Peashrub > green bean > alfalfa. Regulation effect in runoff under different nano carbon contents and different vegetation coverage were consistent with different nutrient losses. After artificial simulation rainfall, nutrients in top soil profile under different types of vegetation decreased significantly, but with the increase of the depth, the nutrient loss became decreased, which indicated that rainfall runoff could take soil nutrient of the surface layer, but most of them would be leached into the deep soil. Nutrient content decreased with the increase of depth of the soil profile, moreover, the nutrient loss was quite different due to different applied nano carbon. The average concentration and the average loss rates of different nutrients in runoff decreased when the nanometer carbon concentration increased, the regularity is obvious.
